A San Mateo Bridge accident on State Route 92 prompted an emergency response Thursday, October 1, 2026, after a traffic collision was reported on the major Bay Area bridge.
The crash was reported on westbound California State Route 92 near the San Mateo Bridge high-rise in the Foster City area.

The San Mateo-Hayward Bridge carries State Route 92 across San Francisco Bay, connecting Foster City in San Mateo County with Hayward in Alameda County. The bridge serves as an important connection between the Peninsula and East Bay, meaning even a single-lane collision can quickly affect traffic approaching the span.
