A traffic collision involving two vehicles, a semitrailer and a grey BMW, occurred today on Interstate 280 North near the Cesar Chavez Street West on-ramp in San Francisco, CA. The incident took place around 7:45 AM during the busy morning commute, leading to significant traffic disruptions.

Emergency units responded quickly to manage the scene, blocking 3 to 4 lanes of traffic on the northbound side of Interstate 280.
