Three designs for a new bridge over the Kenilworth Channel for the ongoing Southwest light rail expansion project were released by the project office Monday, carrying descriptions such as Arched Pier Concept, Thin Deck Concept and Steel Pier Concept.
Once built, the new bridge will replace a mid-century timber rail bridge that now carries a freight rail line as well as runners, walkers and cyclists on the popular Kenilworth Trail. Beneath is the channel that connects Cedar Lake and Lake of the Isles that is used by canoers, kayakers and — when it freezes over — cross-country skiers.
According to the alignment approved by the Met Council and consented to by the cities along the 16-mile expansion, the new bridge will also have two tracks for light rail trains. But the bridge itself has drawn objections from the Minneapolis Park and Recreation Board because board members and senior staff think it will disrupt the pastoral nature of the channel — not just from increased rail traffic but from the mass of the new bridges themselves. The board would prefer that a shallow tunnel be built for the light rail trains to travel beneath the channel.
Park board spokeswoman Dawn Summers said the staff and members had just received the designs and were not able yet to comment on them.
According to a press release from the Metropolitan Council’s Southwest Project Office, which accompanied the designs, the bridges are designed to be “reminiscent of the existing railroad bridge and are fashioned to fit in with the natural surroundings.”
Based on comments from organizations and agencies that are being consulted on the design, the three concepts try to “minimize the visual impact and hazards for channel users.” To that end, all three “would be supported from below only with just three rows of piers, down from the six on the existing wooden railroad bridge. Poles holding the overhead wires that carry electricity to power the trains would not be located on the bridge. In the current concepts, they would be set substantially back from the banks of the channel.”
The other design suggestions were to maximize the space between the two bridges and create more space in the channel by reducing the number of piers, to use natural materials and to use a “utilitarian” design.
Among those being consulted on the project are the Minnesota Department of Transportation, the State Historic Preservation Office, the Minneapolis Park and Recreation Board, the city of Minneapolis and the Kenwood Isles Area Association.
The cost of the new bridge is estimated at between $4 million and $7 million.
Yuck!
The first one looks like bridges you can see over freeways anywhere in the metropolitan area. And the third one looks like it was built with scrapped out materials left over from some construction project.
At least the second one isn’t so in-your-face, although the illustration including the train really increases the visual incongruity of that great big yellow-and-white behemoth traversing the span (which was the first thing my eye was drawn to when I got to that one).
It’s a start
That first concrete bridge is essentially the same design that the Greenway runs over the Lagoon on, so you can go look at that if you want. The second design strikes me a “brutalist” revival… not good. And the last one might be better with a different railing?
anything but what we have
The most hideous design, ironically, is the one the park board wants to save.
What these images avoid showing — no doubt intentionally — is the incongruity of scale: the proposed bridges are humongous compared to what is there now! As a park board official pointed out, the bridge, which would carry 220 LRT trains a day, would be on the scale of a freeway bridge. What a desecration of the Chain of Lakes!
We chip away at our lakes with bridges, trains, pollution, development — diminishing them incrementally. The end point? The Twin Cities will be “a cold Omaha.”
scary imagery!
But reviewing the “artists’ conceptions” attached to this article, the proposals don’t appear to approach a ‘freeway scale’ bridge. My recollection of the chanel is that it’s a bit dark, narrow and dim; the railroad bridge is a creosote stained eyesore, perhaps including some corrugated steel; though I admit I could be confusing it with bridges along Minnehaha. In any case, the argument against a new light rail bridge over the channel vastly over estimates the degree to which the channel is detrimentally impacted. A new concrete structure would be a significant aesthetic improvement over the current bridge.
Artificial Waterway
This is a artificial waterway, built by by the Park Board to connect a swamp (Lake of the Isles) to Cedar Lake.
