FONTANA, Calif. (AP) — A big-rig crashed into an overpass on Interstate 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 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.
