It's probably easier to list the highways in Wyoming that are open than it is the ones that are closed following a record-setting winter storm over the weekend.
The Wyoming Department of Transportation reports that I-80 from Laramie to Rawlins has re-opened, but that both I-25 and US 87 from Cheyenne to Wheatland are currently closed due to winter conditions and crashes.
In Wyoming, much of I-80 is closed due to a Rolling Closure and Winter Weather Conditions. Over 350 Miles of I-80 between Evanston and Cheyenne are closed.
In a sign that the Cowboy State is in the middle of winter, the Wyoming Department of Transportation has ordered the closure of some highways while issuing advisories for others.
