Carquinez Bridge
Replaced with a beautiful suspension bridge in 2003, the Carquinez Bridge carries vehicles, bikes and pedestrians westbound across the Carquinez Strait. (The eastbound span carries vehicles only.)
The Carquinez Bridge is actually two bridges. Located near Vallejo, on Interstate 80 between Contra Costa and Solano counties, the original crossing opened in 1927. To accommodate the ever-increasing traffic flow on I-80, in 1958 Caltrans constructed a parallel bridge to function as the eastbound span.
The original span was replaced in 2003 by a graceful suspension bridge. It carries westbound vehicular traffic across the Carquinez Strait, as well as bicycles and pedestrians on a bicycle and pedestrian pathway.
How many bikes and pedestrians have crossed the Carquinez Bridge since 2016? What times of day do most bikes and pedestrians make the trip?
The Carquinez Bridge, also known as the Alfred Zampa Memorial Bridge, is named for the late Bay Area ironworker Al Zampa, who helped construct the original Carquinez Bridge and other Bay Area toll bridges.
