Lingering travel impacts could last as long as Thursday across many portions of the region and even Friday for portions of I-80 west of Laramie to Rawlins.
Interstate 80 between Cheyenne and Laramie is now open to all traffic in both directions, but Interstate 25 between Cheyenne and Wheatland remains closed.
A Wyoming man was killed late Wednesday night after he was hit by a semi while trying to get his car unstuck from the snow, the Wyoming Highway Patrol says.
