Bicycle paths on interstate freeway bridges
Tuesday, May 23, 2006
Bicycle and pedestrian advocates in the Kansas City area have been proposing to include a separated bicycle/pedestrian path as part of the new Paseo Bridge.
Some have objected that such facilities are rare, difficult, or dangerous.
In fact, as the following list shows, such facilities are increasingly common in the United States.
Interstate freeway bridges in the United States with bicycle/pedestrian crossings Note: This is only a partial list.
Interstate 90 floating bridges across Lake Washington, Seattle - lanes plus bike/ped lane immediately adjacent, separated by a cement barrier.
I-494 over the Mississippi River near Minneapolis, Minnesota - path is immediately adjacent to the freeway, separated by a stone barrier.

Expressway type facilities, similar to interstates, with bike/ped on bridges
The new Cooper River Bridge in Charleston, SC, is not an interstate but has 8 lanes of fast motorized traffic and has a ped-bike facility. The people who claimed no one would use it have been proven wrong--the biggest complaint is that it can get crowded.
The Golden Gate Bridge, Hwy 101, San Francisco--sidewalk on each side. This is considered a freeway.
The Page Avenue Extension near St. Louis has 10 lanes of fast motor traffic and an attached bicycle/pedestrian path
Interstate bridges that allow bicycle traffic on shoulders Bicycle traffic on these bridges is on shoulders that are not physically separated from the freeway traffic
