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.

The Antioch Bridge is one of four (the others being the Benicia-Martinez, Carquinez and Dumbarton bridges) state-owned toll bridges that currently have bicycle and pedestrian access.

Caltrans and BATA evaluated the seismic safety of the bridge and determined it requires seismic retrofit work to make the bridge safe during a major earthquake.
