Traffic along the 10 Freeway in Los Angeles.
A big-rig crashed into an overpass on I-10 east of Los Angeles, shutting down the entire westbound side during evening rush hour.
The California Highway Patrol says the tractor-trailer hit the overpass bridge at Citrus Avenue in Fontana about 50 miles east of LA shortly after 5 p.m. Thursday.
Westbound traffic is backed up for about three miles.
It was not immediately clear how long the freeway would be closed for or whether anyone was injured in the crash.
