UPDATE:

I-80 reopened Thursday afternoon and is open across the state of Wyoming. 

==============================================================

Interstate 25 in Wyoming reopened Thursday, a day after the arrival of what's being reported as the worst blizzard since Thanksgiving of 1979.

Due to winter conditions, Interstate 80 across the Cowboy State remains closed eastbound between Evanston and Laramie and in both directions between Laramie and the Nebraska state line.

The Wyoming Department of Transportation expects I-80 to be closed overnight.
