A traffic collision involving two vehicles occurred today on northbound Interstate 280 (I-280) near Alemany Boulevard in San Francisco, CA. The incident took place during the morning commute, involving a silver Toyota Prius and a black Mercedes E-Class. Both vehicles were left drivable after the crash.

The collision led to lane closures on the highway, significantly impacting traffic flow. Emergency response teams quickly arrived on the scene to manage the situation, and traffic management units were deployed to secure the area and facilitate the clearance process. As a result, motorists experienced delays and congestion in the affected lanes during peak travel hours.

The traffic incident was reported shortly after 7:30 AM, and by 8:00 AM, crews were actively working to clear the roadway. Despite the prompt response, drivers faced significant backup as they navigated through the area.

Motorists are advised to seek alternate routes if possible and to remain cautious while driving through the scene, as residual delays may persist even after the incident has been cleared. Staying informed about traffic updates can help avoid unnecessary delays during your travels.
