The crash occurred on westbound State Route 92 on the San Mateo-Hayward Bridge.
According to reports citing CHP traffic information, the collision initially blocked lanes near the high-rise portion of the bridge, creating substantial congestion for motorists traveling between the East Bay and the Peninsula.
Officials advised drivers to expect delays and consider alternate routes while emergency crews and traffic personnel worked to clear the affected area.
Highway 92 Traffic Delays
The San Mateo-Hayward Bridge is a major commuter route, so the collision quickly affected traffic approaching the bridge.

Bridge Traffic Later Improved
The most recent traffic-camera information available later Thursday showed the San Mateo-Hayward Bridge clear with no active incident, indicating that the earlier crash-related disruption had been cleared by that time.
