Meet Your Bay Area Bridges

The Antioch Bridge is the only regional bridge which extends outside the Bay Area, into Sacramento County. The original Antioch Bridge was built in 1926. Its replacement opened in 1978.

The Benicia-Martinez Bridge (along with the San Francisco-Oakland Bay Bridge) is a designated “lifeline” structure, built to transport first responders and emergency supplies, even after a major earthquake.

A suspension bridge replaced the original westbound span of the Carquinez Bridge in 2003, while the eastbound span is a steel cantilever truss bridge built in 1958. The newer structure also is known as the Alfred Zampa Memorial Bridge, named for the late Bay Area ironworker Al Zampa.

The original Dumbarton Bridge, which opened in 1927, was the first vehicular crossing over San Francisco Bay proper. It was replaced in 1984 by a new bridge that now provides three lanes in each direction, as well as a bicycle/pedestrian path.

More than 160,000 cyclists and pedestrians have crossed the Richmond-San Rafael Bridge path since opening in November 2019. The path links the Bay Trail between Marin and Contra Costa counties.

The striking visual icon of the San Francisco-Oakland Bay Bridge is the most heavily-traveled bridge in the Bay Area, accounting for nearly 40% of all daily bridge trips in the region.

Spanning 7 miles, the San Mateo-Hayward Bridge is the longest bridge in California (and the fourth-longest bridge in the entire United States).

This span offers some of the best views of the San Francisco skyline and the bay. If you're ever in Lisbon, Portugal, look for the "25 de Abril Bridge," a suspension bridge similar in design and color.
