Southwest LRT: Triage Now, Rehabilitation Later

It’s clear that nothing is clear when it comes to figuring out how freight rail, bike trails, neighborhoods, and our Chain of Lakes can exist in harmony with the planned Southwest Light Rail line. This doesn’t come as a surprise to anyone who has remotely followed the development of this line over the past decade.

As the planning process has gone on, it appears we have two sides retreating further to opposite positions:

The public consensus seems to be that nodes like Uptown, Lyn Lake, and Eat Street deserve connectivity to our regional transit network, especially with such a high public investment at stake. It does, after all, seem ridiculous to consider hundreds of millions of dollars for features like a risky shallow tunnel through Kenilworth and viaducts/tunnels to suburban parking lots / unwalkable offices in Minnetonka and Eden Prairie, but not reconsider connecting regional destinations and dense housing nodes to high quality transit.

Planners and officials, on the other hand, have doubled down on a route that was chosen under changed cost-effectiveness guidelines to move suburban commuters and congestion-causers faster and farther at the expense of urban transit users. As Peter Wagenius astutely noted, “There are folks who are extraordinarily invested in validating the process that has brought us to this point.” The reality is this is a regressive plan, but it appears we’re stuck with it.

The political reality remains that Southwest LRT’s path is hung up by two intractable positions. Without canceling the project and starting over, where do we go from here? Here’s a comprehensive look at how we can make decisions now that set ourselves up for quality transit in the long term.

Triage

If we’re going to build light rail in the Kenilworth Corridor, there are a few steps we can take to triage the plan and make it healthier from the start with a better chance for improvements in the long run.

  1. Build a single track in the tight Kenilworth Corridor between West Lake and Penn stations.
    At an average speed of 45 MPH (55 MPH max speed plus accel/decel at each end) it would take roughly 2 minutes for a train to get from West Lake to Penn. As long as headways are over 5 minutes (they’ll probably be somewhere between 7.5 and 12 minutes) there would not be an issue. Single tracking segments is quite common on many LRT systems around the country, so there’s precedent for the type of signaling and coordination necessary to pull it off. The result would be that we can have co-location of freight, LRT, and the recreational trail without risking as much tree canopy or our wonderful Chain of Lakes.
  2. Eliminate the planned station at 21st Street.
    The shallow tunnel option would also remove this station, so clearly it’s politically palatable in the context of mitigated co-location. Even if we could build it, the reality is that the existing and potential land use around the station node is not conducive to such an expensive investment. This station was planned using questionable numbers and assumptions. If you think the bustling Uptown Transit Station would have only 100 more riders than the isolated 21st St Station in 2030 (as claimed by the LPA decision process), I have a bridge on the St. Croix to sell you.
  3. Build the Midtown Greenway streetcar to LRT spec between West Lake and Nicollet.
    The planned “streetcar” is grade separated and will use light rail vehicles. So this isn’t much of a stretch from what is planned today, except for stations. Stations west of Nicollet should be built to handle 3 LRV trains rather than single LRVs running in streetcar mode. You’ll see why in a minute.
  4. Integrate the West Lake station to accommodate Southwest LRT and Midtown Greenway streetcar.
    This has operational benefits in the short term, and network benefits in the long term. In the short term, it means a cross-platform or single-platform transfer between the two services. It also allows Greenway LRT to share an operations and maintenance facility with our light rail system. Turnaround for Greenway LRT/streetcar service can be accommodated by a pocket track just west of the West Lake station (this is the same technique used on the Blue Line when the starter segment opened to Ft. Snelling station, turning around at the pocket track just south of the platform).
  5. Build Arterial BRT on Nicollet rather than a streetcar. For $200 million, it doesn’t make sense to install rails that share right of way. It will make it that much harder to build the transit we deserve when we finally realize our densest neighborhoods should have high-speed high-capacity connectivity to Downtown and other neighborhoods.

Rehabilitate

By triaging Southwest LRT and allowing it to be built now, we will have greater flexibility for transit network improvements in the future. This part of the plan is how we take a flawed Southwest LRT concept and build upon it for decades of transit excellence.

Those who decided on the Kenilworth alignment over the Uptown alignment think buses are good enough. They’re not. Someday, when we invest in transit to connect neighborhoods rather than park and rides, we will benefit from taking small steps now to use forwards-compatible.

The planned Green Line to Penn can be repurposed in the future to connect to St. Louis Park’s West End via BNSF right of way, and potentially other job centers further west along 394. This would connect a corridor with nearly as many jobs as the proposed Southwest corridor. Not to mention that the 394 corridor actually has higher job density and more walkability than many of the job nodes along the Southwest portion.

What would be done with the Southwest line we’re planning to build now? At some point the primary east-west spine along 5th Street downtown will be at capacity with four lines operating as two services (Blue and Green). But I sure hope we see a future with more than four LRT lines connecting the region.

At that point, we’ll have to get serious about a second spine for LRT service. Nicollet Ave is an obvious choice, especially the segment currently under consideration for our starter streetcar. If business impacts on Nicollet south of Franklin are a concern, a cut-and-cover tunnel under Blaisdell may be more appropriate. Because of #3 and #4 above, we’ll be ready to tie in from the Greenway to the Nicollet corridor to head downtown. And this grade transition would conveniently happen at the site of the infamous Kmart which is on borrowed time. Think of it as 3C by retrofit.

When this is done, we can still accommodate rail service running the entire length of the Midtown corridor from West Lake on the Green Line to Midtown on the Blue Line. Furthermore, we’d have even greater flexibility to extend Midtown service on the west due to #4. Finally, the 3C retrofit would share urban right of way with other services we may want in the future, such as a line up Central Ave to Fridley, or a diagonal to Rosedale, or a line south to Richfield or Southdale.

In this scenario, what would happen to the planned single track Kenilworth alignment between West Lake and Penn (#1 and #2)? It would actually still provide quite a bit of value. It would connect multiple future rail lines that would cross downtown at 5th and Nicollet, allowing them to share vehicles and facilities. This was actually one of the primary marks against 3C in the LPA process, besides trouble interlining with the Green Line. The Kenilworth single-track segment would solve this gap, outside of downtown. Secondly, it would offer flexibility to provide peak-hour express services from Eden Prairie, which was also another knock against 3C back in 2009.

What would Minneapolis get out of this? Options. When we come to our senses, we can build quality transit to Uptown, without risking FTA New Starts funds or the planning process thus far. We’d also have mitigation. As noted, a single track would likely require less destruction of the tree canopy in Kenilworth. It would be easier to keep the bicycle path in the same corridor. And, down the road when we do decide to put transit where it makes sense, Kenilworth neighbors would only have to deal with a dozen or two passenger trains a day rather than hundreds.

To paraphrase Voltaire, we can’t let the perfect be the enemy of the good. Yet, at the same time, we can’t let the immediate be the enemy of the future. Southwest LRT is being pushed forward through Kenilworth, and there aren’t easy answers. But, with a few simple changes, we can make sure our choices now provide the best outcomes decades from now when we have an even more progressive vision for mobility in our region.
