I-10 WB closed at Bullard Road after vehicles collide with semi

11/5/15: A crash involving two passenger vehicles and a semi truck has closed Interstate 10 westbound at Bullard Avenue about 17 miles west of downtown Phoenix.

Officials said the semi truck broke down in the center lane of traffic when it was struck by two other vehicles at about 11:45 a.m. The Arizona Dept. of Transportation says drivers can use the exit and entrance ramps at Bullard to get around the crash, but drivers should expect heavy delays.

There's no estimated time to reopen westbound lanes. Eastbound lanes remain open.
