A significant traffic incident occurred today on State Route 1 South in San Francisco, CA, involving four vehicles: a red sports car, a white Chevy sedan, a black BMW S5, and another vehicle with unspecified details. The collision resulted in major traffic disruptions, blocking both southbound lanes of the tunnel and causing extensive backups that reached adjacent roadway junctions.

Emergency services swiftly responded to the scene, deploying multiple units to manage traffic and restore flow. While some vehicles were deemed drivable, at least one required towing. Traffic management measures were implemented, including the issuance of a signal alert due to the complete blockage of the southbound lanes at the junction with U.S. Route 101.

During the evening rush hour, commuters faced significant delays and congestion, with traffic reported at a standstill and backups extending all the way to U.S. Route 101. Emergency crews worked diligently to clear the scene, and by approximately 6:30 PM, the roadway was reopened, allowing traffic to resume.
