San Mateo-Hayward Bridge in Lincoln, CA (Google Maps)

The bridge is signed as part of California State Highway 92, whose western terminus is at the town of Half Moon Bay on the Pacific coast. Its principal function is to link Interstate 880 in the East Bay with U.S. Route 101 on the Peninsula. It is roughly parallel to and lies between the San Francisco-Oakland Bay Bridge and the Dumbarton Bridge, and is sometimes used by commuters to avoid traffic delays due to emergencies on those bridges.

The main span over the ship channel located near the western end was built with six lanes, while the long eastern causeway was built with four lanes, two in each direction, planned for eventual expansion to six lanes. The four lane section was quickly overwhelmed by traffic and not until 2004 was the final expansion to six lanes completed, along with much needed improvements in its connections with Interstate 880 in Hayward.

Bus service over the bridge is provided by AC Transit's Line M and Line MA transbay service.

High-voltage power lines built by PG&E parallel the bridge all the way across the bay. They provide power to the Peninsula and San Francisco.

As of 2007, the toll is $4, and is collected for westbound traffic only. The second and third far left toll lanes are dedicated FasTrak lanes. Carpools carrying 2 or more persons are permitted to bypass the far left toll lane for free during weekday morning and afternoon commute hours. The bridge is owned by the state of California, and is maintained by CalTrans, the state highway agency.

The San Mateo-Hayward Bridge is a bridge crossing the San Francisco Bay in the US, linking the San Francisco Peninsula with the East Bay. The original bridge was built in 1929, and upon completion was the longest bridge in the world. It was subsequently replaced with a modern span in 1967. The total length of the bridge is 7 miles (36,960 feet / 11,265.41 m / 11.27 km). It is composed of multiple steel girder spans that make up the high rise, measuring 1.9 of the total 7 miles. The other segment is made up of the Trestle portion, accounting for the remaining 5.1 miles. It is currently under extensive seismic retrofitting to withstand a powerful earthquake. The bridge carries about 93,000 cars and other vehicles each day.

Its western end is in Foster City, the most recent urban addition to the eastern edge of San Mateo. The eastern end of the bridge is in Hayward.
