The crash happened around 2:15 p.m. near the Tunnel Road exit and involved at least two vehicles.
SKY7 was over the scene which showed a junk truck with a smashed front end and windshield next to another work truck.
An ABC7 Eyewitness News photographer was able to capture the moment a man was loaded into an ambulance with what appeared to be lower leg injuries.
CHP has not released details on the man's condition nor what may have caused this accident.
