A traffic collision on US Highway 101 North at the Cesar Chavez Street West on-ramp in San Francisco, CA, caused significant traffic disruptions today. The incident occurred around 9:16 PM and involved two vehicles: a blue Honda compact car and a silver Honda two-door sedan. The silver Honda sustained minor front-end damage and was towed from the scene, while the blue Honda impacted a guardrail.

Emergency services arrived promptly to manage traffic and control the scene, addressing a partial blockage of the on-ramp. This obstruction led to delays for drivers attempting to merge onto US Highway 101 North, contributing to congestion in the area. By 9:50 PM, the tow truck had cleared the silver Honda, allowing for the gradual reopening of the on-ramp.

Motorists are advised to remain cautious in the vicinity, as residual traffic may continue to affect travel times. The California Highway Patrol is actively monitoring the situation to ensure a smooth flow of traffic as the area returns to normal conditions.

As always, drivers are encouraged to stay alert and follow posted traffic signs and signals to ensure their safety on the roads.
