RICHMOND, Calif. — Motorists traveling toward Marin County are being urged to prepare for significant delays following an accident on the Richmond–San Rafael Bridge earlier today. The collision has caused slow-moving traffic stretching from the toll plaza through the first incline, creating congestion during an already busy travel period.

According to preliminary reports, the incident occurred on the westbound lanes heading toward San Rafael. While details regarding the number of vehicles involved or the extent of injuries have not yet been confirmed, emergency crews were dispatched quickly and are actively working at the scene. Drivers have reported reduced speeds and stop-and-go conditions as lanes remain partially blocked.

California Highway Patrol officers and bridge personnel are managing traffic flow while assessing the situation. The presence of emergency vehicles has further narrowed available lanes, contributing to backups that continue to grow. Commuters heading toward Marin County, including those traveling for work or afternoon appointments, are experiencing longer-than-usual travel times.

Officials are advising drivers to use caution when approaching the bridge and to consider alternate routes if possible. Nearby roadways and connecting highways are also seeing increased volume as motorists attempt to avoid the slowdown. Navigation apps are reflecting extended delays, with estimates varying depending on traffic conditions and response time.

No official timeline has been released regarding when the scene will be fully cleared and normal traffic restored. Drivers are encouraged to stay informed through local traffic updates and to remain patient while crews work to resolve the situation safely.
