San Francisco County, California Bridges: Illinois Street Bridge across Islais Creek

July 2014 (37.74740, -122.38617) Illinois Street Bridge

The last movable bridge in San Francisco County is the Illinois Street Bridge. Sitting one block away from yesterday's Third Street Bridge, it is a single leaf bascule bridge without counterweights. Instead, the bridge is raised and lowered by hydraulic cylinders that pull and push on lever arms connected to the steel deck. Perhaps this is the future for bascule bridges? It was built in 2006 by Shimmick Construction and others. It doesn't have a county bridge number because it's owned by Bay Area Rapid Transit (BART). It was built between San Francisco Port's north and south terminals, mainly for trucks, but also with sidewalks for bikes and pedestrians and with rails for freight trains.
