Least-traveled and probably least known of the region's toll bridges, the
Antioch also is the only bridge to reach outside the nine-county Bay Area.
From Antioch in northeastern Contra Costa County, the bridge arches over
the San Joaquin River, touching down in Sacramento County.
Until recently, travel across the Antioch Bridge has remained relatively
stable, but growth in the city of Antioch and nearby Contra Costa towns such
as Pittsburg and Brentwood is now causing traffic on the Antioch Bridge to
increase at a faster rate than on any other of the region's toll bridges.
One of the newest of the toll bridges, the Antioch Bridge is one of only
two (the other being the Dumbarton) that were determined by Caltrans to not
need seismic retrofit work. The Antioch Bridge also shares another distinction
with the Dumbarton the two are the only state-owned bridges that currently
have bicycle and pedestrian access. There are no plans at the present time
to widen the Antioch Bridge.
