A traffic collision involving three vehicles occurred today on the southbound lanes of US Highway 101 near the interchange with Interstate 280 South in San Francisco, CA. The incident took place during the morning commute, resulting in significant traffic impacts as lane 5 was blocked. A gray Honda SUV was involved and subsequently towed from the scene, along with a black BMW SUV and an unknown vehicle.

Emergency traffic management units responded quickly to the scene to manage the situation and clear the blockage. Initially, the collision caused delays and congestion, but by approximately 9:07 AM, lanes 1 through 4 were reopened, allowing for improved traffic flow. However, lane 5 remained blocked for a longer period, contributing to backups in the area.

Drivers in the vicinity were advised to exercise caution and expect potential delays as emergency responders worked to clear the scene. The Department of Transportation Control Center was notified to assist with traffic control during the incident. As the situation was resolved, normal traffic patterns began to resume, alleviating the earlier congestion caused by the traffic incident.
