One person is dead after an auto-pedestrian crash near Del City, police said.

The crash happened about 2:45 a.m. Friday on Interstate 40 near Sooner Road.

She was reportedly hit by a tractor-trailer who pulled over a short distance away from the crash.

The woman was identified as Tristen Wadja, 23, of Yukon. 

Troopers have narrowed westbound I-40 to one lane while officers investigate the crash. 

Motorists are asked to avoid the area if possible.
