A traffic collision on the southbound lanes of U.S. Highway 101 near the East Washington Street off-ramp in Petaluma, CA, has resulted in significant traffic disruptions today. The incident occurred around 7:35 PM and involved three vehicles: a blue SUV, another vehicle that ended up on the opposite side of the guardrail in a grassy area, and a third vehicle embedded in the guardrail with notable front-end damage.
Due to the collision, debris has spread across the roadway, leading to the closure of the East Washington Street off-ramp. Motorists are advised to expect delays and congestion as traffic is being diverted. Emergency response teams, including multiple units and Caltrans personnel, have arrived on the scene to manage traffic and secure the area.
Drivers approaching the scene are urged to exercise caution while navigating around the damaged guardrail and debris. The ramp closure is likely to impact evening traffic, particularly for those using the off-ramp. A tow truck has been requested to assist in clearing the vehicles involved in the incident. Caltrans is actively working to restore normal traffic flow as quickly as possible.
Motorists are encouraged to seek alternate routes to avoid potential backups and delays.
