The San Mateo–Hayward Bridge (commonly called the San Mateo Bridge) is a bridge crossing the American state of California's San Francisco Bay, linking the San Francisco Peninsula with the East Bay. The bridge's western end is in Foster City, a suburb on the eastern edge of San Mateo. The eastern end of the bridge is in Hayward. It is the longest fixed-link bridge in California and the 25th longest in the world. The bridge is owned by the state of California, and is maintained by California Department of Transportation (Caltrans), the state highway agency. Further oversight is provided by the Bay Area Toll Authority (BATA).
The bridge is part of State Route 92 (SR 92), whose western terminus is at the city of Half Moon Bay on the Pacific coast. It links Interstate 880 (I-880) in the East Bay with U.S. Route 101 (US 101) on the peninsula. It is roughly parallel to, and lies between, the San Francisco–Oakland Bay Bridge and the Dumbarton Bridge.
