An accident involving a semi-truck and other vehicles shut down state Route 94 Monday afternoon and sent one person to the hospital with an injury, according to the California Highway Patrol.

The jack-knifed big rig blocked all lanes of traffic after the accident, which was reported about 12:30 p.m. Monday near Federal Boulevard on westbound SR-94. 

According to the CHP, at least three or four other vehicles were involved in the wreck, including two taxi cabs and a sedan. The truck driver as well as the driver of a Nissan Rogue were both transported to a hospital for evaluation and treatment of possible arm and shoulder injuries.

The collision prompted a Sig alert for the area, and backed up traffic for more than an hour. A CHP spokesman says all lanes were re-opened about 1:45 p.m. and a CalTrans crew was still on the scene cleaning up debris. 

It's not clear what triggered the accident. 10News is reporting the crash is under investigation, with the CHP looking at the possibility that a green Mitsubishi cut off another car which might have caused the semi to spin out.
