Carquinez Bridge
Carquinez Bridge

The Carquinez Bridge is actually two bridges. The original crossing opened in 1927, and to accommodate the ever-increasing traffic flow on Interstate 80, Caltrans in 1958 constructed a parallel bridge to function as the eastbound span. The original span was replaced in 2003 by a graceful new suspension bridge, which carries westbound vehicular traffic across the Carquinez Strait as well as bicycles and pedestrians on a bicycle and pedestrian pathway.

The bridge is named for the late Bay Area iron worker Al Zampa, who helped construct the original Carquinez Bridge as well as other Bay Area toll bridges.
