A big rig overturned Wednesday morning on the southbound Golden State (5) Freeway in Sun Valley and the wreckage blocked three lanes of traffic for several hours.
The crash occurred near Glenoaks Boulevard about 2:20 a.m., according to the California Highway Patrol.
The trailers detached from the cab when the semi overturned, prompting the closure of the carpool and Nos. 1 and 2 lanes of the freeway until about 7 a.m., the CHP said.
No injuries were reported. It was unclear what caused the semi to overturn.
