Why Minneapolis SHOULD Consent to the SWLRT Tunnel Plan

[For an opposing take on the SWLRT tunnel, see Kasia’s post here.] 

The Southwest Light Rail (SWLRT) corridor, otherwise known as the Green Line Extension, sure is one heavily debated and contentious project.  While there are technical and political questions along the entire route, what to do about routing freight, LRT, and bikes through the Kenilworth Trail between West Lake Street and 394 is undoubtedly the biggest issue to overcome if the project needs to get off the ground.

Not literally …unfortunately.

Multiple options have been presented, including re-locating freight through St Louis Park, both deep-bore and shallow cut-and-cover tunnel options to keep freight and trail facilities at-grade, re-routing the bike trail, and even buying out 26 townhomes in the narrow portion to keep all modes at-grade. However, the Metropolitan Council and other groups seem to be settling on the shallow tunnel as the most viable option.  Minneapolis residents and leaders are worried about the ramifications of this option:

  • Loss of trees throughout the trail
  • Disruptions to the trail during construction limiting bicycle recreation and commuting in to downtown
  • Potential threats to the Chain of Lakes if the tunnel is not engineered or constructed properly
  • Degradation of the trail as a scenic, quiet space thanks to 220 trains per day entering and exiting the two tunnels at four points

Governor Dayton just issued a delay to the project to force the team to look at other options for freight re-location and evaluate the environmental impact of the shallow tunnel options.  This is a wise move to ensure all potential alternatives are evaluated, but my guess is that there won’t be other freight options and a room of smart engineers will come back confident they can mitigate environmental impacts.

I’ve been a major skeptic of this line for a while.  I’m skeptical of many of the assumptions the ridership models used, skeptical of the ability for stations in suburban locations to really sprout walkable land-use patterns, the fact that we’re willing to consider a tunnel through woods but not under population/employment centers on other lines (both CC and Bottineau), and (somewhat related) skeptical of the routing decision to bypass Uptown and Nicollet Ave.  With that said, I’m here to have some fun, stretch my debating skills, and be honest about some positives of the LPA, and will therefore do my best to argue why Minneapolis leaders should give municipal consent for the shallow tunnel option, with two major caveats: 1) remove the tunnel north of the channel between Lake of the Isles and Cedar Lake (saving $50-60 million), and 2) the Midtown Greenway streetcar and Nicollet Ave enhanced bus/streetcar projects are implemented.

Tunnel Option Provides Transit Connections

It’s absolutely crazy to assume that a 3C alignment running up Nicollet would have zero transfers to or from the Central Corridor, just as it would be for any other line it crosses.  It’s also right to question what the Kenilworth alignment gives Minneapolis for quality transit stops.  However, a SWLRT with only a southern tunnel has potential to give riders a single transfer (or better) experience to (and within) many Minneapolis destinations (or, Minneapolis residents a similar experience to SW suburb destinations).

Present (or Under Construction) Lines

  • Central Corridor. Running the SWLRT through Kenilworth in an effort to interline with the nearly complete Green Line has operational benefits (using one train to continue from St Paul and the U out to EP).  By proxy, an interlined train with offers SWLRT access to multiple downtown stops without transferring.
  • Northstar.  While I admit it’s unlikely riders from the Northstar Line will choose riding in to downtown, transferring to another line, and riding it out to the suburbs (at the very least, more riders than would hit Uptown), at least they can do so with a seamless transfer at the Interchange.

Planned Lines

  • Midtown Streetcar (I dub thee the Yellow Line!  More on this one later).  While this still isn’t fully funded or a sure thing, far more detailed plans have surfaced in recent months about running a high frequency, wide stop spacing streetcar (most likely a single light rail vehicle) from the West Lake station to the Midtown Blue Line station.  This gives Uptown folks a single transfer, rapid transit connection if heading SW, and vice versa.  Those wishing to go further east will hopefully have the Nicollet Lake Street Enhanced Bus as a second bonus option for transferring at West Lake.
  • Nicollet/Central Streetcar/Enhanced Bus.  (Okay, Streetcar, we know that’s what’s we’re getting)  Folks north the Midtown Nicollet stop’s walk shed along Nicollet and Central will have a comfortable, one-transfer ride to hop on the SWLRT by heading in to downtown to transfer.
  • Blue Line Extension.  While the Bottineau corridor extension of the Blue Line is planned to bypass some population centers of its own, the Interchange transfer point (as opposed to Nicollet) saves time for Northsiders heading out to job centers in Eden Prairie.

Potential Improvements

  • 21st St Station Bus Transfer.  If the northern tunnel section is nixed, a 21st St station offers the opportunity to improve bus connection to Franklin Ave.  Extend the 2 to a pickup/”kiss and ride” and designate Franklin as a corridor worthy of stop enhancements, strategic ROW, and off-board fare collection to increase speed.
  • Penn Avenue and Chicago-Fremont aBRT.  Slight modifications to the location of stations just NW of downtown can provide rapid, frequent, high amenity bus routes to reach the SWLRT Kenilworth alignment sooner than a 3C (Nicollet) alignment, saving North Minneapolis residents total ride time to the SW ‘burbs.
Why is Metro Transit missing these opportunities??

All of these connections have real benefits to citizens of Minneapolis from many neighborhoods, even if a potential Uptwon alignment may serve more residential and job centers today.

Disruptions to Infrastructure Happen.

Let’s be honest, Minneapolis residents.  Worrying about short-term disruptions to the trail due to tunnel construction is a bit silly.  This happens to people all over the world when re-paving, new construction, or improvements happen.  Trees can be re-planted in the corridor.  Yes, it might not be as shady or quite so bucolic for a few years, but thinking about this area long-term is much less emotional than the short-term loss.

Artists' renderings are NEVER wrong.

Artists’ renderings are NEVER wrong.

While I’m proud to say Minneapolis has such high-quality bicycle infrastructure (well, relative to US cities, anyway), will losing the trail for 1-2 years during construction be the end of the world?  Why not use this as an opportunity to improve permanent bicycle infrastructure in other places to aid the process?  Fight for reduction in thru- or parking lane(s) on Hennepin and install quality segregated cycle tracks as a negotiating tactic.  Hopefully a high-capacity, frequent rail service takes away vehicle pressure of people from Hopkins and SLP using Hennepin as a cut-through to downtown, so the engineers concerned about car traffic are satiated (holding my breath..).  Let’s stop viewing this as a threat and turn it in to a major opportunity.

As to the trains moving through the trail.  They’re electrically powered and therefore much quieter than typical trains, and emit next to no pollution.  Successful neighborhoods all over the world have trains running right outside their front or back) doors.  Any negative effect on property values due to bells ringing should be mitigated by the increase in transit service the neighborhood receives (particularly if the 21st St station is retained).   Minneapolis should consider changing its Comprehensive Plan to allow for some density along the trail.  It’s possible that the value of a single family home may degrade slightly with a transit line in its back yard, but a developer may see the proximity to a trail and LRT line as a major positive and be willing to pay more per acre than your typical family with 2 kids and a dog.  Just sayin’.

Hope for the Future

Building the trail through Kenilworth doesn’t necessarily rule out a future Uptown (3C) alignment for a SWLRT.  A shallow tunnel preserves the ability for the Midtown (Yellow!) Corridor to interline with the West Lake station.

I won’t get too geeky here (since there are likely a million technical challenges to this plan), but down the roads it’s possible to serve Uptown to Downtown by way of fast, frequent, fixed rail while keeping the tunnel useful.

Rapid_Transit_Fantasy

Perfect? No. Politically achievable? Maybe.

Transit_Fantasy_Uptown

Serving Uptown with 3 grade-separated rail lines plus a Hennepin Streetcar for good measure.

Once the Midtown Greenway Streetcar is built (which should eventually interline with the Blue Line, cross the river at 46th St, hit the Ford Plant redevelopment, and follow the now useless CP line to meet up with the Riverview Corridor LRT), we can build a tunnel running under Nicollet or 1st Ave and (ideally) in a tunnel through downtown, serving NE Minneapolis.  The current Green Line can interline with the Black Line to the SW burbs if desired, and when demand warrants frequency upgrades, Metro Transit can consider a branch running out to the West End (and potentially further to Wayzata).

Ok, one can dream, right?.  But the reality is that building a tunnel now doesn’t necessarily rule out a SW-Uptown-Downtown rail line in the future.  Plus, as stated earlier, the investments that are likely coming to Uptown will help take the load off the slow, late bus service that exists today.

Hopefully I did a decent job convincing myself and astute, opinionated readers that a tunnel option for the SWLRT isn’t the dumpster fire we’re all thinking it is.  Happy commenting!!

    There are numerous other benefits you missed for Kenilworth:

    – Royalston is a big transfer point for Northsiders TODAY and would be a great connector to jobs in the southwest suburbs via SW LRT.

    – Ditto Van White. We just built a fabulous bridge, meaning the station will be accessibl to those going to/from places like the basilica and Loring Park.

    – The Basset Creek Valley master plan is centered around the Van White station. We have the potential to redevelop blighted dumping grounds close to downtown!

    – The “yellow line” will provide quick service to the Blue Line to/from Uptown. That can’t happen with a 3C LRT alignment. We could do a streetcar from Niicollet to Hiawatha but it seems too short to be worth it and would require a transfer (not the end of the world, of course).

    I struggle with the Royalston connection (although implicity noted it as a current connection that saves N Mpls residents time by not heading downtown). The closest bus stop serving North Minneapolis (unless I’m mistaken) is the 5, on the north side of Olsen Memorial, and a full 1,300+ ft from the location of the Royalston station. While not an impossible transfer, that’s still a minimum of 5 minutes walk time, not ideal conditions, and then however long to transfer. Could obviously be much worse, and with a little work could be much better, I suppose (my point in highlighting Penn/Fremont aBRT lines and missed opportunities). But yes, those are all general positives of the 3A routing (assuming the BCV redevelopment happens and isn’t auto-focused that happens to have a LRT stop).

    I’m confused how a Midtown Corridor/Yellow line couldn’t continue interlining with a 3C alignment west of Nicollet. Like I states, I’m sure there are a few technical details, but the “Black Line” (future 3C) could exit the Greenway to the south under a K-Mart redevelopment, bulb out as it descends to a depth below the trench, and head north under 1st. It’s certainly possible.

    The “jobs” argument is consistently fascinating to me. We should skip two of the densest job centers in the metro to get to another on in the southwest suburbs a few minutes faster. Both 3A and 3C alignments serve jobs in SW, but only one would give people access to thousands of Uptown jobs (and more access to Nicollet Mall jobs). Here’s a map comparing job density between the two alignments: http://netdensity.net/wp-content/uploads/2009/07/SW_LRT_Employment.pdf

      No doubt. I wrote this as a fun exercise, but I completely agree that the jobs argument is suspect as long as the line continues out to Minnetonka and EP. Uptown is booming, not just in residential population – Mozaic Phase III will really solidify it as a strong office location and I suspect many more will follow.

      It seems to me the rationale made for the reverse commuters from N Mpls is that the extra time getting in to downtown to transfer (instead of at Target Field or Royalston) and then the extra 5 minutes travel time heading west makes the difference? I suppose that’s probably a 10-12 minute adder for those trips. Is it worth it?

      I’m very skeptical how much (good) development will really come around the Van White station, so that’s what makes me write that off as a real silver bullet positive. Perhaps that’s because I’d rather see the city be accepting of re-development, incremental density, and transit improvements where it’s already naturally occurring thanks to proximity to natural, cultural, and job amenities (greater Uptown).

    “my guess is that there won’t be other freight options and a room of smart engineers will come back confident they can mitigate environmental impacts.”

    I don’t want to sound like an asshole, and I don’t mean this question rhetorically: are they smart engineers?
