The Antioch Bridge spans the San Joaquin River, connecting northeastern Contra Costa County to Sacramento County.
The least traveled of the region’s toll bridges, the Antioch is also 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 six state-owned toll bridges that currently have bicycle and pedestrian access.
After Caltrans and the Bay Area Toll Authority evaluated the seismic safety of the Antioch Bridge, a 2013 seismic retrofit project was done to make the bridge safer during a major earthquake.
