Big-rig flips in LA freeway, 8-hour commuter mess

The California Highway Patrol reopened southbound lanes of Interstate 5 some eight hours after a flipped big-rig shut down travel lanes and led to a long morning of gridlock for commuters and truckers.

Traffic came to a halt after Tuesday's 3:58 a.m. crash in the Sylmar area near the Roxford Street exit, about 30 miles north of downtown Los Angeles. At times, the backup extended at least 10 miles on Interstate 5 and 14.

CHP Officer Miguel Luevano says California Department of Transportation crews had to scoop up bales of recycled cardboard and diesel fuel spilled by the rig, which was on its side across travel lanes.

The trucker wasn't seriously hurt.

The cause of the crash hasn't been determined.
