The
Carquinez Bridge is actually two bridges. The original crossing opened in
1927, and to accommodate the ever-increasing traffic flow on Interstate 80,
in 1958 Caltrans constructed a parallel bridge to function as the eastbound
span. The original span now serves westbound traffic and is the oldest structure
among the region's existing toll bridges.
While the 1958 span has been strengthened under Caltrans' seismic retrofit
program, the 1927 span is being replaced as part of BATA's Regional Measure
1 toll bridge program. The new replacement suspension bridge has been built
just west of the existing spans, and opened to traffic in November 2003.
