By Alexander Ross
The severe choke point on the southbound side centered around mile marker 138, directly south of Oak Hill Road. According to California Highway Patrol logs, the incident involved a motorcycle and at least one passenger vehicle, leaving debris scattered across hundreds of feet of roadway.
