St. Louis May Be One of Few Cities in the World With an Elevated Bikeway
|
The message to the crowd was simple — the Great Rivers Greenway District already owns the old elevated railway trestle that runs from Hadley and Cass to the McKinley Bridge and they want to turn it into one of the world’s few elevated bikeway and walking trails. Inspiration comes from Paris’ Promenade Plantée and New York’s planned High Line. Chicago and Philly are also working on similar projects.
A good crowd (a “few” if KSDK were counting) gathered last Thursday evening at the Confluence Academy in Old North St. Louis to hear the early thoughts on the proposal. Questions centered around specifics and planners had to continue to remind everyone that this in the very beginning stages — no specifics are known other than what it is they own and control.
Paris and New York are the only two cities with elevated bikeways. Chicago is looking at doing the same thing but they don’t yet have control over the trestle they have in mind. The following are some of the images from the presentation:
The idea is to have a bike path, a walking path, message boards, native greenery and to make creative use of the old supports for the electric wires that powered the old interurban lines.
Some of the concepts they presented included wind, sun and rain collection.
They hope to encourage adjacent buildings to add green roofs to improve the experience, reduce the heat island affect and reduce energy costs for those owners. Taller trellis’ would be added where necessary to prevent people from gaining access to roofs from the trestle.
One idea they explored is to widen the trestle at a point or two to gain more “plaza” space and room for viewing.
One nice thing is the prominent view from I-70. Greening up the trestle and incorporating signs would hopefully increase the curiosity of motorists.
A small portion of the trestle is already being prepared for such a use — connecting to the soon to re-open McKinley bridge. This will give cyclists an easy route to Illinois.
One potential issue is the proposed Mississippi River Bridge — it would intersect with I-70 immediately south of where the trestle crosses. Although the clearance from the highway to the bottom of the trestle is fine, it does not meet current standards. MoDot is seeking Federal approval to allow for an exemption so the trestle can remain in place. Of course, no final design or funding has been worked out between Missouri and Illinois on this bridge so it is anyone’s guess when and if I every actually happens.
I’d like to see I-70 removed from the area between downtown and the arch but part of me doubts that would every actually get removed even if a new bridge for I-70 traffic was built. I’d like to see the MacArthur Bridge, located to the south of the Poplar Street Bridge, reopened to auto traffic, or perhaps as another bike/pedestrian bridge like the Chain of Rocks (the MacArthur still carries railroad traffic below the former auto deck).
Despite the potentially high cost, I think retaining these old industrial structures and reusing them for bike connection is a worthwhile pursuit. The connection with the wonderful North Riverfront trail at Branch Street would be great.
