Bottineau-no for North, part III

Here is the last of my three-part Bottineau rant, which at this point may be considered a full-fledged tirade.  Somewhat coincidentally, it arrives on the same day the Minneapolis City Council makes its recommendation for a Locally Preferred Alternative, which is more or less required by the FTA for the project to advance.  It looks like the Council has acquiesced to the LRT D1 alternative – Wirth-Olson – but with the clever stipulation that Hennepin County and Metro Transit agree to develop at least one arterial transitway through North Minneapolis along Penn, Emerson/Fremont, or West Broadway.  I’m not aware of any attempt by the city to gather their citizens’ opinions, outside of  the county-led process, but of course you can always provide input to the Bottineau project office.

My last post proposed the consideration of an LRT subway through North Minneapolis, which would do a zillion times better job of serving the heart of the Northside without the impact of a surface route, and based on our history with Hiawatha is unlikely to be as expensive as other recent American below-grade transit projects.  An LRT subway will not be considered in Minnesota – it’s just too “coastal.”  In that case, I think the best alternative for Bottineau would be BRT on West Broadway.  This was actually considered in the AA study, and scored well enough that it just barely missed the arbitrary cutoff to make it to the scoping phase.  Actually it would have probably made the cutoff (unless the cutoff was again raised to exclude it) if the AA study hadn’t penalized all BRT alternatives.  See for yourself- here is the Traveler Time Savings (in regional minutes per day) measure from page 76 of AA study:

Not enough minutes in the day

The study claims that “LRT alternatives outscore BRT alternatives on this measure because they have shorter end-to-end travel times” which is interesting because a) the BRT and LRT alternatives would follow identical alignments, and b) technically buses and trains are capable of the same operating speeds.  Because the chart above is pretty much the most detailed information in the AA study about travel times, I’m not sure how they determined that BRT alternatives would take longer than LRT in the exact same alignment.  The study also projected fewer riders for BRT alternatives, but not nearly enough fewer to explain the missing minutes.  Here is a comparison table I made using data from the AA study:

This chart teases us with a clue:  It may have had something to do with the Interchange, Hennepin County’s platitudinously named train station, which is the only point where some LRT and BRT alternatives diverged.  Specifically, D3 and D4, the former of which does significantly worse on traveler time savings, are assumed to run “on a busway parallel to the I-94 viaduct” then to turn south a block to stop at the Interchange, then proceed eventually a block back north to 4th St.  This is a terrible idea.  If they were actually thinking about how to maximize the benefits of the transportation system, D3 and D4 would have an advantage over the other alternatives because they could use the viaduct itself.

The 4th St Viaduct (should be plural, since there are actually two viaducts) is massively overbuilt.  It is two lanes in each direction, but caters primarily to peak traffic, leaving at least half the roadway underutilized at all times.  If one viaduct were made reversible, the other could be used for a two-way busway, providing a transit advantage into Downtown Minneapolis.  In addition, if the south viaduct were used, it could provide an even better, if more expensive, connection to the Northstar station than LRT would:

Which would you prefer?

The viaduct could connect directly to West Broadway with a little modification of the existing interchanges.  Basically a ramp could just be added from West Broadway to the existing ramp from I-94 to the viaduct, and then another ramp from that ramp over to the other viaduct.  It’s a bit trickier to connect the westbound viaduct to westbound West Broadway.  The Alexandrian way, depicted below, would just build a flyover from the viaduct to the 94 ramp to Washington, at which BRT could have signal priority.  Ideally the BRT viaduct would connect to I-94 so express buses could use it too, which could be done by adding a ramp going straight where the westbound ramp bends to meet Washington.  In addition to a station at the Interchange, there could be one serving the densifying North Loop at 8th or 10th Ave N.

Green is BRT, Yellow is I-94 access, Red is the relocated ramp from I-94 to Lyndale Ave

Another reason the West Broadway BRT (D4 on the chart) scored well in general is that it wasn’t really BRT, at least not east of Penn, where the alternative studied would operate in mixed traffic.  This was done to “eliminat[e] the need to disrupt traffic or remove businesses.”  Of course, disrupting traffic is to some degree the goal of developing transitways; you want to shift traffic from cars to transit vehicles.  But is disrupting traffic or removing businesses necessary to accommodate BRT on West Broadway?

As I mentioned above, West Broadway is 80′ east of Penn, and they cram in four through lanes and parking in many places.  Traffic counts hover around 20,000/day, but drops off steeply west of Emerson/Fremont, so that the counts west of Morgan are around 10k/day.  Assuming west of Girard only two traffic lanes are needed, guideway will fit there without widening even on the 75′ sections – assuming a 28′ guideway and two 11′ through lanes, 25′ are left over for sidewalks or maybe parking in some places.  East of Girard, 28′ will be needed for guideway and at least 40′ for four through lanes (suck it up, Hennepin County and MnDot, 10′ lanes works for much busier streets, even with trucks).  That means the road will need to be widened slightly (mostly 90′, but possibly 100′ at stations.)

Widening this area of West Broadway would not be like widening Penn.  Frankly, there aren’t many buildings left to destroy here.  If the widening was taken from the north side of the street east of Fremont (there should be just enough room on the block west of Fremont for 90′ with tearing down buildings – the bright side of setbacks), then switch to the south side east of Bryant, there should be room for 90-100′ without tearing down anything except the small cluster west of Emerson.

Joe Gladke, Hennepin County’s Manager of Engineering and Transit Planning, mentioned in a presentation to the Minneapolis TPW Committee that LRT and full BRT was dropped from West Broadway because of business owners’ concern over loss of parking.  That’s like being concerned over loss of sand in the Sahara.  I did a quick measurement of parking lots in the West Broadway business district and found that 16 of the 64 acres between Girard and 94, 18th and 21st are parking lots – that’s 25% of the gross area!  (And that’s not counting the 550 space lot that will be built with MPS’ new headquarters.)

Lots of lots (sorry I couldn’t resist)

So it’s possible to build reserved-guideway BRT on West Broadway that won’t disrupt traffic and will remove only a handful of businesses.  This alignment would go through the heart of North Minneapolis, serving thousands more residents, and present ample opportunities for TOD (see vast parking lot fields above).  Based on the cost estimates from the AA – where BRT generally came in at around half the cost of LRT – it would still cost substantially less than the proposed LRT alternatives.  That would allow perks like the conversion of the 4th St Viaduct to a combined reversible roadway and two-way busway, which would serve an additional high-density neighborhood and provide a benefit to the express bus network.

The lower cost of BRT would also allow both Brooklyn Park and Maple Grove to serve as termini for the same price, although the AA study didn’t find benefits commensurate to the costs of serving both branches.  I stubbornly maintain that if we’re going to spend regional money on a development-inducing transitway, it would benefit the region more to serve existing struggling activity centers like Brooklyn Center rather than provide a further incentive to fringe development.  But the other advantage of BRT, apparently unexplored in the Bottineau process, is that multiple routes with vastly different termini can branch out after using the busway, known as Open BRT.  So Maple Grove and Brooklyn Park could both be served, even if the guideway continues to Brooklyn Center, as could Plymouth, New Hope, Crystal or even Rogers.

I hope I’m not focusing on BRT because of the recent flak Hiawatha has taken from anti-transit ideologues, who nonetheless have a valid point about how expensive the line is both to build and to operate.  Central and likely Southwest serve enough high-density areas that they’re likely to better justify their costs, and since Hiawatha serves major regional destinations like the airport and the MOA it will likely benefit significantly from the network effect of three light rail lines.

Bottineau, on the other hand, doesn’t serve a major regional destination outside of Downtown Minneapolis, so it is unlikely to benefit from a network effect outside of the meager one accounted for in the AA study.  The Wirth-Olson alignment serves only one relatively high-density and high-poverty neighborhood – around Van White – and has few potential candidates for redevelopment inside the beltway.  It runs through almost three miles of parkland for chrissakes!  It just doesn’t make sense to spend a billion dollars on a transitway with that little potential.  It’s unlikely my proposal for full BRT on West Broadway will be considered in the DEIS, much less an LRT subway in North Minneapolis, but I hope that BRT stays in the running.  I want to believe in LRT for Bottineau, but it looks like BRT is a better option.

People are already walking to the future Golden Valley Road station

Bottineau-no for North, part II

In my last post, I went through some of the reasons why existing land use is unlikely to support even the medium-capacity transit system provided by LRT or BRT Bottineau alignments.  In the absence of inflated commuter ridership figures, the only compelling reason to build the line is economic development.  But if Bottineau is being built primarily for economic development, why is it avoiding the most economically disadvantaged part of the state?  If Bottineau is supposed to encourage the development of housing and jobs along the line, why not route it to areas in need of redevelopment rather than to the fringe?  Why should we spend a billion dollars to just encourage more development on the edge of town?

If a goal of the line is economic development, there is a better northern terminus:  Brooklyn Center.  According to DEED data compiled by the Met Council, Brooklyn Center lost more than 5,000 jobs between 2000 and 2010, which is no more than a crumb of the Metro area’s total jobs (around 1.5m), but represents almost a third of the jobs once held in this community within easy commuting distance of some of the state’s poorest neighborhoods.  Developing a major job center on the old Brookdale site would have been ideal from a regional planning standpoint:  more so than the sprawling Arbor Lakes area (this is where a pedestrian was recently hit and killed by a car while on the sidewalk), and especially the fringe site of Target Suburban Headquarters, Brooklyn Center is adequately served by existing transportation infrastructure, including an easy (if theoretical) bus ride from the Fridley Northstar station.

Target Suburban HQ on Brookdale's footprint

Right-of-way is readily available in the median of Hwy 100 – at about 25′, it’s not quite wide enough for LRT guideway, so it would likely require some reconstruction of the roadway, probably shrinking the outside shoulders a bit – and alongside Shingle Creek Pkwy further north.  The most expensive elements would be flyovers from the BNSF track north of Robbinsdale onto Hwy 100 and from the freeway onto Shingle Creek, and widening or replacing the bridge over Twin Lakes.  I depicted a station at France, but since that would require a good 45′ of median, the full roadway would need to be reconstructed and the overpass replaced, so the low-density area probably wouldn’t immediately be worth the expense.  Anyway by the time this is built, Surly will probably have moved to their “destination” brewery, so no big loss.

This route may seem indirect, but I think it makes more sense in terms of regional connectivity and suburb-to-suburb travel.  Assuming a network of freeway BRT-ish routes, a more complete grid would be formed by extending a Hwy 100 route along Bottineau Blvd north of Robbinsdale rather than jutting east to Brookdale.

Would a Brookdale route be time-competitive with cars?  Google says that the fastest route from Brooklyn Center Transit Center to 4th & Hennepin is 13 minutes without congestion.  Based on the average speeds of Hiawatha, a light rail version of my proposed route running in a tunnel from the BNSF line to Plymouth and I-94 would take 17 minutes from Bass Lake Road (near Brooklyn Center Transit Center) to the Warehouse District station, about 30% longer than google  (and much less time than the existing express buses, which go through Camden and take about a half hour).  That compares well to Central LRT, which takes about 29% longer than the 94 route (if you believe the dubious claims) and a whopping 89% of google’s drive time.

Approx. route for Bottineau on bedrock map of North Mpls - red is segment in tunnel

Of course, tunneling is expensive, and as I mentioned above, it’s hard to believe the Penn or Wirth-Olson alternatives will deliver the ridership to justify even surface-running light rail.  But we’re not talking about New York or Seattle here – North Minneapolis lies on an excellent surface for deep-bore tunneling, easy-digging sandstone capped with a solid, stable roof of limestone.  Best of all for a Northside route, the portals would both lie in a sandstone layer.  Based on Hiawatha’s tunneling costs, the 5 km required for a Northside LRT subway would cost $300m, about a third of the projected costs for the other LRT alternatives.  Best of all, it would reach the heart of North Minneapolis without destroying existing communities or severing the street grid.  I think it’s worth considering, but the project managers do not.  Here is an email I sent them two years ago and their response:

Subject: complete Alternatives Analysis for Bottineau


In order to completely evaluate the alternatives for the Bottineau corridor, another alternative should be considered that would be light-rail or bus in a tunnel through North Minneapolis.

Minneapolis and Hennepin County are finally ready for world-class transit and, considering the major overhaul in Federal transportation funding due next year, the Federal government may finally be ready to give Americans the quality in public transit that they deserve (and that has been exclusively bestowed on the motoring public up to now).

North Minneapolis has some of the highest rates of transit ridership in the Twin Cities, and, after a history of public disinvestment in the area, they deserve a high-quality transit line. I am confident that, if projections take into consideration a built-out transit system, the ridership would justify the higher cost. It would also benefit the suburban commuters as a grade-separated direct route would likely offer the quickest travel time into and out of downtown Minneapolis.

I have more ideas about an North Minneapolis subway alternative for the Bottineau Corridor, and, if you’re interested, I’d be happy to expound on them. If not, I thank you for your time.

Subject: Re: complete Alternatives Analysis for Bottineau

Mr. Bauman,

Thank you for your email regarding the Bottineau Transitway Alternatives Analysis Study and your thoughts regarding a tunnel alignment concept through North Minneapolis.

We share your interests in providing high quality transit services for Twin Cities residents including those who live in North Minneapolis.

As you likely know, our study process is being conducted in collaboration with FTA guidelines as they exist today. Hennepin County is also actively engaged in policy development and FTA proposed rule making regarding transitway investment programs in collaboration with our Minnesota legislative delegation in Washington DC.

Like you, we are also looking forward to potential changes in the Federal Transportation Re-authorization Bill and how this bill may lead to enhance the quality of transit provided in the United States, the Twin Cities Region, and Hennepin County. Should the transportation bill direct transformational changes in the way transit investments are made, Hennepin County and other units of government will be obligated to study the implications of these changes on the Bottineau Corridor.

However, we also think you deserve a sober historical perspective and look to the future regarding the potential to pursue a transitway tunnel design through North Minneapolis. As you’ve indicated, tunnels are costly (often in the range of 10 times the amount of a surface facility) and need substantial user benefits in order to justify their costs. It is instructive to consider that transitway tunnel construction in this country has been implemented through densely populated areas and/or high activity centers. Examples that come to mind include New York City, the Seattle Central Business District, and the San Francisco Central Business District. Relatively short segment tunnels have also been implemented for high activity centers such as San Diego State University Campus, the University of Washington Campus (entering construction at a expected cost of $1.95 Billion), and the Hiawatha LRT tunnel beneath our Minneapolis St. Paul International Airport. It should also be noted that tunnels tend to be implemented with high capacity transit modes such as subway metro lines. These systems provide higher capacity/utility than intermediate capacity BRT or LRT mode systems and can more easily justify tunneling costs.

The most recent local example of transit tunneling investigation/feasibility is for the Central Corridor LRT segment along Washington Avenue through the U of M campus. The cost estimate for a 2,050 foot tunnel was $128 Million above the cost of a surface running facility. This translates to a per mile cost of $329 Million. This estimate assumes no stations in the tunnel segment (stations add substantially to the cost of underground construction). It was determined that this tunnel segment was not feasible and the current Central Corridor LRT project includes a surface transit operations along Washington Avenue.

The approximate distance between 36th Avenue in Robbinsdale and the Minneapolis Transportation Interchange facility near Target Field is approximately 4.7 miles [He appears to be measuring here using the Wirth-Olson alignment, as though I'd suggest putting that already largely grade-separated alignment in a tunnel.  As the crow flies, the distance between 36th & the Interchange is 3.7 miles, and as I mentioned above, I think a tunnel could be limited to about 5 km. - Alex]. Using the $329 Million per mile cost from above to illustrate a rough order of magnitude, the cost of a transit tunnel through North Minneapolis could be in excess of $1.5 Billion without accounting for station facilities. This would more than double the current Bottineau Transitway alternative cost estimates.

North Minneapolis is a mix of single family with some higher density multi-family dwellings. This area does have relatively strong transit ridership now and potential into the future. Considering the growing needs around the country for transit investments one can appreciate how transformational the transportation re-authorization bill and funding program would need to be in order to justify long tunnel segments through lower density neighborhoods like North Minneapolis for intermediate capacity transit service like LRT.

In summary, your input is appreciated and we look forward to assessing how the federal transportation re-authorization bill will affect transitway concepts for the Bottineau Corridor.

Please let me know if you have additional questions or would like more information.

An LRT subway station in a suburb of Stuttgart mostly characterized by single-family homes

He does a good, and probably justified, job of making me sound crazy.  He also builds his argument around tunneling projects that are entirely unlike those that would be reasonably considered for Bottineau.  I already mentioned that Minneapolis has a much more stable geology for tunneling than Seattle’s Ring of Fire location or New York’s famously hard and unstable schist.  Sandstone is called sand stone for a reason.  The Washington Ave example is more subtly inapplicable – a cut-and-cover tunnel was proposed for an extremely dense environment; even the cut-and-cover tunnel on Nicollet in Whittier studied for Southwest LRT was expected to cost less, and a deep-bored tunnel would certainly be less expensive per mile.  Finally, it’s ludicrous to suggest that LRT systems are rarely in tunnels; there are dozens of counter-examples, including Bergen’s system, which has around half the per km cost of Hiawatha despite running in tunnels for a quarter of its route.

It may seem inconsistent to say that land use doesn’t support the Wirth-Olson LRT proposal, but at the same time to champion an LRT subway.  The difference is a matter of objectives – the existing Bottineau process has the objective of “improving regional mobility” in the context of a transportation-engineering institution that has been slowly evolving over the past few decades until it at last includes factors such as effect on low-income communities.  But Bottineau as proposed runs through low-density areas, serves few job centers and generally avoids low-income communities, so it doesn’t really meet that objective.

A Bottineau process that considered a light-rail tunnel would probably be too expensive to meet traditional quasi-economic standards (though those traditional standards are giving a green light to a $700m roadway to carry 25,000 cars across the St Croix River), so it would need to come out of a more holistic institution, one that considered urban development  (and underdevelopment) and social justice (and injustice) along with transportation.   We do not live in a nation that considers urban development or social justice; instead we are a nation that is beholden to its land speculation industry and ignores centuries of racial discrimination while asserting a veneer of pluralism.   That is the nation we live in, but those of us who spend more time living in an ideal nation in the sky or in our heads will continue dreaming of an ideal transportation system, one that includes an LRT subway for North Minneapolis.

The next and final segment in this series will take us back to reality somewhat.  If reality is more your sort of thing, look for it here next week.

Bottineau-no for North, part I

I’ve always wondered how Central Corridor – running on existing right-of-way and enhancing what has long been an overburdened bus line serving thousands of low-income Minnesotans – can be compared to I-94 – which tore down entire blocks for a dozen miles to serve higher-income motorists.  Still the NAACP has been tenacious in their lawsuit against the project, which may be less of an indication of the staying power of racial issues than the depth of NIMBYism in American culture.

The Penn Alternative

That’s why it’s even more difficult to understand why the Bottineau Transitway project is still considering an alignment that would affect dozens of properties along Penn Ave.  I went to one of the recent open houses and heard the nervous queries of residents whose houses would be taken.  On top of the question of sensitivity towards racial issues in light of the history of racial iniquities perpetrated by the transportation engineering profession, the project mangers should remember that each resident is a prospective plaintiff.

All my streets, Lord, soon be widened

Not that it’s a terrible plan, if you forget that its subject area is a city in the USA with a typically long history of racial injustice.  Certainly the Northside was platted with too narrow streets – the quarter’s central artery, the inaptly name Broadway, is 80′ for only a mile east of Knox, but I believe it’s North’s widest street not counting the frontage road that is Washington Ave.  The Penn Alternative would widen the street to around 90-100′, assuming 20′ for two sidewalk/boulevards, 26′ for guideway, and 44′ for through and parking lanes.  The plan as pdfed includes some superfluous right turn lanes but otherwise is pretty close to what a quality design for an enhanced streetcar line would look like.

The biggest problem is that even the City of Minneapolis acknowledges, in its comments to the Scoping phase, that “it is not known whether [the parcels that would need partial takings for the Penn Alternative] could be redeveloped.”  Of course they could be redeveloped, especially in conjunction with the remainder of their blocks (i.e. the parcels facing Queen), but the question is whether there would be money and will.  The former is self-explanatory, the latter is a cultural issue – after a chunk of the parcels were taken for redevelopment, they wouldn’t meet the city’s “buildable” standard for single family lots.  I would say that only a dysfunctional culture would even want to build single family homes along a light-rail line, but we are still deep in the cult of Nimby, so that is what any community-based plan would likely call for.  Even if by some miracle apartments were proposed, developers would likely find the narrow parcels awkward for building.  Redeveloping the whole block would be expensive, politically difficult, and given the track record of large-scale public redevelopment in this country, potentially ghettoizing.

I guess it’s the Wirth-Olson alignment then

Double beg button on the wrong side of the pole from the walking path

Olson Highway is easily one of the worst roads in the state – an extremely wide ROW littered with beg buttons and broken sidewalks and a median that’s often less a refuge than a corral – so I hope that the city, county and state take this as an opportunity to improve it.  Unfortunately, preliminary concepts for the alignment along Olson put the track in the median.  This despite Olson’s 25k AADT, which easily fits on two lanes in each direction (and does fit on two lanes further west on Olson), especially with Olson’s ample room for turn lanes.

As much as LRT would improve Olson, I’m not sure I can support it on the Wirth-Olson alignment.  It’s a classic Dallas scenario – the line would strategically avoid all of the dense areas that would supply it with riders.  More than a year ago, Yonah Freemark pointed out that Dallas has the longest light rail system in the country, but still manages to skirt its densest neighborhoods.  Unfortunately we are seeing a similar path of least resistance followed in the Twin Cities of the North, where the Olson-Wirth alignment’s densest neighborhood would be Robbinsdale, where the 5.2 households per acre is closer to the standard for intermediate frequency bus service, and a bit more than half of what’s required to support light rail.  Densities are actually lower along Olson in North Minneapolis, where the local Hope VI renewal project replaced the rowhouses of Sumner Field with fewer units than were destroyed.

TLC's awesome employment density map, from their 2008 Transportation Performance Report

Commuter ridership is a dicey proposition as well.  While Downtown Minneapolis has slightly more jobs than Downtown Dallas, the prospects for reverse commuting are much lower on Bottineau than on any LRT line developed or proposed here so far.  Using the job cluster map produced by Reconnecting America, you can see that Hiawatha serves around 45,000 non-CBD jobs, most of which are clustered around the airport and MOA stations (that’s not counting Minneapolis South, which contains 26,000 jobs but stretches far west of Hiawatha).  Central LRT will serve a remarkable 125,000 non-(Minneapolis) CBD jobs, again mostly clustered along the line.  Southwest LRT will hit around 55,000 non-CBD jobs, although they’re less clustered so perhaps less likely to take the train.

Bottineau, in contrast, serves just two non-CBD job clusters:  Osseo, with a respectable 24,235 jobs, but over a sprawling area that stretches up to three miles from the nearest proposed station; and Maple Grove, with a barely noticeable 3,892 jobs but that still manages to be one of the lowest-density clusters on the map.  While both job clusters are likely growing, the growth would have to be spectacular and compact to begin to approach the job density of other transitways.  Target’s Suburban Headquarters, which is sometimes said to “anchor” the B alternative of the northern end of Bottineau, is projected to grow to a mammoth 5,200 jobs by 2014.

So Bottineau will add maybe 30,000 sprawling jobs to the 371,000 already connected by the three other transitways when it comes online.  It will pass through very low density areas.  It will cost almost a billion dollars.  Are we sure we want to do this?  What are some other alternatives?  I’ll explore them in my next couple posts.

How does your light rail go?

For reasons that will become clear before long, I’ve calculated the average speed on each segment of the Hiawatha line (which apparently for the purpose of marginalizing those with color blindness has been renamed after some color, not sure which).

More precisely, I’ve calculated the average scheduled speeds – I used the posted schedule for the line and Google Earth to measure the track length to get the average speed.  Segments are measured from the apparent midpoint of each platform, and where the two tracks deviate or the tracks disappear under an airport or a megamall I guessed a bit or used the rail layer from GE.

In an interesting twist, the scheduled speeds diverge a bit from the official map.  The map shows 2 minutes between Target Field and Warehouse District stations, but 3 minutes are scheduled, perhaps for padding at this terminal, where I believe trains often reverse.  More mystifying is the reversal where the official map shows 2 minutes between Franklin and Lake and 3 between Lake and 38th, but the schedule switches those.  It makes more sense for the segment between Franklin and Lake to take a bit longer, considering the curve on the viaduct over Hiawatha, so maybe it’s a typo?  Regardless it perhaps shows the folly of relying on the scheduled time to determine average speed instead of observing in the field, but who has time to ride back and forth with a stopwatch?

Oops, forgot to mention that distance is in miles

Hiawatha runs through a fairly diverse set of environments, which I’ve broken down into three categories.  While these are probably imprecisely named, they are fairly consistent.  At-grade and Separated at-grade both have grade crossings, but Separated at-grade has far fewer.  Below grade (which I suppose I should have called grade-separated) has no grade crossings.  The At-grade segments have an overall average speed of 12 mph, while Separated at-grade doubles that to 24 mph.  Below grade is the fastest, with an overall average of 29 mph, but you may have noticed that some of the separated at-grade segments exceed this.

Clearly the segments have characteristics that differentiate them from each other more than my simplified categories suggest.  The fastest segment, between 38th and 46th, is straight and has only one grade crossing [Froggie reminded me that this segment actually has two grade crossings - see comments].  Meanwhile the segments that are largely in tunnels have quite a bit of curvature to them, and since both segments have portals grade may be an issue as well.  And of course some segments have subsegments of more than one category – between the VA and Fort Snelling are sections that are at-grade but largely free of crossings and a long above-grade section.

Central may introduce another category, since the body of it will run at-grade, but with far fewer crossings than Downtown Minneapolis or even Bloomington, yet more than Hiawatha between Franklin and the park.  So who knows if anything valuable will come from this exercise – only the fates can tell…

Traveling in Moderation, part II: Multimodal Mad Town

Having posted the first Traveling in Moderation, a thought popped into my head:  traveling 270 miles really isn’t very moderate.  My great-grandfather left Traverse County only once, for a church-group trip to Pennsylvania.  Our modern standards for travel have been explosively expanded by the availability of cheap oil, and will contract as oil gets more expensive.  So I suppose I should be flying now while the flying’s cheap.  Anyway, let’s get back to Madison…

As built, Madison is one of the most walkable cities in the Upper Midwest.  Most streets are narrow, and the wide ones almost all have crossable center medians.  The grid shifts with primary travel patterns, and is often sliced through with diagonals, for more efficient paths.  The destination density seems pretty good (although it is hard for me to tell with small cities) – grocery stores are pretty well spaced, and walkscore is fairly high excepting some Suburban Hells on the Far West and East Sides.

The result is a good mode share for walking.  Of course, university towns tend to be walking towns and Madison may not be exceptional among its peers (it’s topped by Columbia, South Carolina, which is so walking-friendly that it’s responding to an increase in pedestrian fatalities by ticketing more pedestrians).  Despite a natural advantage for pedestrians and a municipality that seems to have more consideration for pedestrians than most, drivers do not necessarily have a lot of respect for pedestrians.  Williamson Street, north of the Capitol, has 20′ tall pedestrian crossing warning signs on just about every block that are routinely ignored by drivers (and, as Jarrett Walker points out, actually distract drivers from any pedestrians that may be trying to cross).

Look sharp

Ah well, Americans will be Americans.  Madison still has much infrastructure of interest for pedestrians.  I’ll take you on a short tour of Pedestrian Madison, with some side trips to Bike Madison.  Any such tour must begin with State Street, which a prominent Twin Cities urbanist recently dubbed “the best street in the Midwest.

State Street is similar in layout to Nicollet Mall – a two-lane roadway reserved for bikes, buses and taxis is flanked by wide, attractive sidewalks with frequent benches and quality bus shelters (and without pointless meandering) – but there are two important differences.  One is that retail is still alive on State Street, with storefronts packed with the sort of shops found in Uptown Minneapolis.  Think American Apparel, Urban Outfitters and Ragstock.  I say packed because the density of retail is such that second-floor stores are not uncommon – and that’s without any skyways.  Related to skyways, and like them possibly a reason for the tenacity of retail here, is the fact that most of State Street is lined with buildings of the classic Storefront vintage of the 1880s-1920s.  That gives it a more “authentic” feel but frankly is also mostly more interesting, since buildings are much smaller you don’t have the monolithic giant empty glass lobbies that line Nicollet.

State Street is a great street

The Mall of East Campus

Moving down State Street to the University, take a left after the library onto the East Campus Mall.  Though this mall has been under construction for the last three years, those segments that are finished display a streetscape that is even higher quality than State Street, in part because East Campus Mall is a full-on pedestrian mall, whereas State Street is merely a bus mall.  However, East Campus Mall is missing something that State Street has in spades: pedestrians.  They may be deterred by the construction, but probably more by the lack of retail on East Campus Mall and the fact that it isn’t really a crucial connection.  I’m probably overstating it – in comparison with State Street, it’s meager, but there is still plenty of pedestrian activity on East Campus Mall.  For the record, I don’t know if there’s a West Campus Mall.

Look both ways

Before you get too far down East Campus Mall, pause a moment at University Ave.  Although its intersection with East Campus Mall uses colored pavement to highlight the pedestrian crossing, University’s streetscape is generally bleak.  But look closer, and what at first appears to be a wide expanse of one-way concrete has some interesting, skinnying features.  On the north side of the street is a bus-right-turn-only lane, conveyed simply with a solid lane marking and a diamond symbol, with occasional signs permitting right turns.  Between the bus lane and the general traffic lanes is a bike lane that appears to be about 8 feet wide.  Then, on the south side of the street is another bike lane, this one contraflow and protected with a low, mountable, concrete divider separating it from the general traffic lanes.  (See this photo for an overview.)

Generally I’m not very excited about contraflow bike lanes.  University – which is the half of a one-way couplet that’s closer to the heart of campus – may be one of the better candidates for it though.  Considering the high demand for cycling in both directions on this street, they may have had an ineradicable salmon problem anyway, and merely made it safer by making it official.  What I really like about University Ave is the simple, functional way they handle the with-flow bike and bus lanes.  Why mess around with experimental markings when drivers already know to stay away from a solid line with a diamond symbol?

In the green

For now we want to avoid the University Ave traffic, so keep going down East Campus Mall and go up the on-ramp to the Southwest Commuter Path.  Once up there, be careful – while this path, which was carved out of one of the abandoned beds of a double-tracked rail line that slimmed down to single track, is signed for pedestrian use, it’s only striped for cyclists and isn’t really wide enough for both modes.  Clamber over the brightly painted crossings at the corner of Regent and Monroe and follow Monroe to the southwest.

crosswalk envy

In a few blocks you’ll get to a nice little 1920s retail strip similar to ones you’ll find in the neighborhoods of the Twin Cities.  This strip has a couple examples of Madison’s revolutionary attitude towards pedestrians, which subscribes to the bizarre theory that walking should be viable even outside of Downtowns or Universities.  The first clue is the refuge median in front of the new – ahem – Trader Joe’s on the first floor of a condo building.  The great thing about Madison’s ubiquitous refuge medians is that apparently police actually enforce the law in them.  As the picture shows, it actually does snow in cities other than Minneapolis.  Go a block up the street for maybe a deeper indication of Madison’s commitment to pedestrians, where a construction site required closing the sidewalk.  Instead of forcing pedestrians across the street, they also closed the parking spaces and built a concrete enclosure temporary sidewalk.

Before we finish our tour we need to hit Willy Street east of the Capitol, so let’s grab a B-cycle at Regent and Monroe and take the bike path along the shore of Monona to the intersection of Wilson, Williamson and John Nolen Dr.  The B-cycle station is before the intersection, but after you dismount, notice the bright red bike boxes at this intersection.  Cars actually stop behind them, and cyclists actually use them – possibly because the paint allows people to actually see that there’s a bike box there.

Begging for change

About a block behind the bucky-red bike boxes is the last innovation of our tour.  The three-leg intersection of Jenifer and Williamson Sts is designed so that only buses, bikes and pedestrians can access Jenifer from Williamson.  This was presumably done to cut down on cars driving through on mostly-residential Jenifer, but the restriction also provides a slight transit advantage.  Or would, except the traffic signal seems to be programmed to give as much time as possible to Williamson St.  When I pressed the beg button to cross Williamson, I counted full minute without any signal change.  (Of course it changed after I’d already crossed about halfway.)  Neither Jenifer nor Williamson seem to have enough traffic to justify giving Williamson so much priority; hopefully they can reprogram to make the signal change a bit quicker and the intersection will be more helpful.  Frankly I don’t know why any pedestrian would use it currently; there is a striped crosswalk about 60 feet southwest that would be much quicker for crossing Williamson.

The last stop on our tour will be Capitol Square.  We’ve walked and biked long enough for now, so I think I’ll save it for next time.  But as we walk towards the square we’ll go up King Street, which is one of my favorite streets in Madison and worth a few more blathers.  King is on the opposite side of the Capitol from State (which was originally also named King), and the two share a basic form – somewhat narrow, lined with 2-4 story buildings.  What I like about King is that it shows how nice an everyday street can be – just make sure it’s not so wide that you can’t see across it and even if you give two-thirds of the street to cars, it’s still not bad for pedestrians.

Hail to the king

One gate open, another closed

The Hennepin-Lyndale Bottleneck was invented by Thomas Lowry to prevent people from walking between the densest and the second-densest neighborhoods in the city, forcing them to ride his streetcars between Downtown and Uptown.

This charming billboard was located approximately where the gaping maw of I-94 is today.

Ok that’s not true.  The Hennepin-Lyndale Bottleneck sorta just happened, either as a planning mistake, or a product of topography or geography, or maybe due to ideas of transportation efficiencies that were revised as newer, deadlier means of transport were popularized.

Our ancestors seemed to view the Bottleneck as something as a town square, lining it with elegant apartments, important churches, art museums and monuments.  But nothing is so important to Americans as automobility, so the freeway builders didn’t spare the area (although the Lowry Hill Tunnel may be the only gesture they made to the cities they were cutting through, or maybe it was just cheaper than an aerial alignment), more than doubling the paved area and making it nearly nontraversable without a vehicle.

So today the Hennepin-Lyndale Bottleneck is a giant unwieldy mess, which of course means that I have a giant unwieldy plan to fix it.  Unfortunately the giant- and unwieldiness of the plan means it is literally half-baked at this point, so I’m just going to comment on the City’s recent efforts to clean up the mess a bit.

Loring Park Gateway open

'proposed' is now existing, sorry for the confusion

This corner wasn’t bad before, by Bottleneck standards anyway.  But it was awkward, routing cyclists on a sharp turn around a bus bench,  and apparently didn’t accommodate some movements, as indicated by the desire path from this corner over to where the sidewalk continues north up Hennepin.

The addition of bike lanes to 15th St (or whatever it’s called there) was an excuse to spruce up the corner and rationalize the placement of the various elements (it seems that the pesky bus bench has been rationalized out of existence, although there is still a shelter at the stop).  That’s because the city wanted to use this intersection to test out what they call the European Left Turn, which sounds a bit like Wisconsin Yoga but is more like a New Jersey Jughandle for bikes.  It’s good to see more separated bike facilities, but this seems to be another case of the City encouraging sidewalk riding.  I like the connection to the Poem bridge, but that also reminds me of the Loring Bikeway bridge, where the City spends a bunch of money creating a circuitous bypass that everyone ignores in favor of the old, direct route.  Why couldn’t they just have striped a bike lane in place of the left turn/through lane?  Is it really important to retain that queuing space for four or five cars?

The other problem with the European Left Turn is that it presumably will add bikes to an already-crowded corner.  The queue at the corner is often five-deep, and while the realignment of the various paths has better separated bikes from peds, the new curb cut placement has led to a new issue:

A few more creeps*

Luckily the city is well aware that the average American motorist is a creep; that is, she has a tendency to creep past the stop line and into the crosswalk.  So the plan is to not only widen the crosswalk to incorporate the new curb cut position, but to install green colored pavement to delineate it.  The project page implies that the colored pavement has been demoted to paint.  Considering the snow will start to fly in a month or two, that means the demotion may have been extended to the crosswalk itself (like most crosswalks in town).  As the photo above shows, something needs to happen here or the new curb cut will be unusable.

All this realigning, paving and striping did not manage to fix the biggest problem with this intersection: signal programming.  Bikes and peds get the hand when the southbound traffic is stopped for the left turn phase for northbound traffic.  So they have to waste time waiting for the man to let them cross again, even though they don’t conflict with left turning northbound traffic.  This situation is all too common in Minneapolis (see almost every stoplight on Hennepin Ave) but because some lights do keep the man lit up when not conflicting with left turns (see the lights at 5th and 7th on Hennepin), I can only blame it on ineptitude or apathy (some would suggest disdain) for pedestrians on the part of traffic engineers.  In the spirit of Organization before Electronics before Concrete, this change in signal programming should probably have been made before planting the pretty flowers, and should be made before installing the new green pavement or plastic or whatever.

The Wedge Gateway closed

Another change a bit further south down the Bottleneck has somehow made the area even less usable for cyclists.  The sidepath abruptly ends at the ramp to I-94 from Lyndale Ave, and apparently the City was concerned that cyclists would continue on to where ever they are going despite the fact that the City had not made provisions for them to do so.  The solution was to make it more obvious what cyclists are not supposed to do:

Poof! And it's gone

See for yourself how well it’s working:

2 cyclists ignore the new stripes

So here’s an idea.  If people want to bike here, maybe a facility should be built that allows them to do so.  The sidepath could be continued down to Lyndale at the expense of no more than 10 often-unused parking spaces. As part of the same project, raised crossings could be built at all of the intersections, magically transforming the sidepath into a two-way cycle track.

Alternately, the City could continue building overpasses and restriping to prevent people from taking the paths they want.  Bloomington took this route on Lindau Lane, where pedestrians ignored their pointless, capricious, impeding crossing bans.  Bloomington responded by spending $50m to grade-separate the roadway (they blew Orwell right out of his syphilitic grave by calling the project the Lindau Lane Complete Streets and Safety Enhancement project), because everyone knows the best pedestrian environments are created by driving a wide, roaring freeway through the heart of a neighborhood.  Here’s an idea of what the Hennepin-Lyndale Bottleneck may look like, if a Lindau Lane-style complete street strategy is pursued:

The Hennepin-Lyndale Bottleneck will feature easy auto access to the Riverfront

*I actually fudged this photo- the supposed creeps have the green light.  But I’ve encountered the crosswalk blocked by creeps several times so far, I just haven’t gotten a picture.

8/9/11 Transportation & Public Works Committee

A couple interesting items from this week’s TPW committee:

  1. 22nd St E (re)construction.

This is not a typical reconstruction as the street was never “built” – it is still an “oiled dirt” street (a bit of a misnomer; I believe these are original dirt streets that used to be covered with oil in the old style but now are patched with asphalt).  Also, in a fun twist on the typical street “reconstruction,” 22nd will follow a new alignment that will reconnect it to Cedar Ave, only 61 years after it was severed in the ill-advised freewayfication of the Cedar-Franklin-Hiawatha intersection.  Here is the layout:

A connection is made

The plan is a vast improvement over the existing street – the narrowed intersection with Snelling banishes the menace of speeding trucks that make the city’s industrial districts so unpleasant.  Right now 22nd St is connected to Cedar Ave with a crumbly staircase; presumably the roadway and sidewalk connections will be a much better option for the many potential users on wheels.

The Project Map included in the committee report omitted two things:  First, a left turn lane on Cedar, which Seward Neighborhood Group and Redesign want here in order to close Minnehaha Ave between Franklin and Cedar.  The city believes that there will be too much traffic in the future to close that road, however, and as far as I know they are planning to reconstruct the intersection with a very similar layout to what is there today.

Ghost ramp

Second, the map is missing a connection from the new 22nd St to the Light Rail Trail.  The existing connection runs on public right-of-way that is being used as parking for some anonymous industry, and consists of a steep curb that is softened by a wood plank.  Sometimes the excitement of the connection is enhanced by repositioning the wood plank in lots of dangerous ways.  Apparently the long-term plan is for the main neighborhood connection to the trail to be at 24th St, but it seems like now may be a good time to add a cheap asphalt ramp or something at 22nd St.

As you can see, the project map is not very detailed.  It’s possible those two omitted items are actually a part of this project.  I couldn’t find any more details on the project page, though, so we’ll have to wait and see.

2.  Lowry Bridge Bike Lanes

There’s a ton of confusion about whether or not there will be bike facilities included on the new Lowry Bridge, despite their inclusion on the Minneapolis Bike Master Plan of 2001.  Apparently 10 years wasn’t enough time for Hennepin County to find time to look at that plan, so they designed the Lowry Bridge without bike facilities (or narrowed the bridge to save money and thereby chucked the bike lanes?  Thanks guys).  Now they say they can find room for lanes or a separated trail somewhere, but the layout dated 8/30/10 included in the TPW committee agenda doesn’t show them.  Maybe the county just hasn’t gotten the new layout to the city, or maybe they didn’t find room yet, or maybe they just told bicycle advocates they’d try to find room and then went upstairs and had a smoke and somebody spoke and they went into a dream.  We’ll know in “Summer 2012″ at the latest.
