UPDATE:

WYDOT advises that Interstate 80 is open all the way across southern Wyoming.  US 287 between Laramie and the Colorado border has reopened as well.

Original Story:

Interstate 80 between Laramie and Cheyenne is closed in both directions due to winter conditions.

The Wyoming Department of Transportation still has I-80 westbound between Laramie and Rawlins closed.  Between Rawlins and Rock Springs, I-80 is completely closed.

US 30/287 between Laramie and Rock River is closed, as is US 287 between Laramie and the Colorado state line.
