A crash involving hazardous materials has forced the closure of Interstate 80 between Rawlins and Laramie, the Wyoming Department of Transportation says.
Since the completion of the I-25 underpass construction near the intersection of N. Walsh Dr. and Western Ave, the new traffic lights that were installed there have not been active.
The Wyoming Highway Patrol is reminding drivers to move over or slow down for roadside workers following Tuesday morning's crash on Interstate 80 west of Cheyenne.
