The heavy post-eclipse traffic in Wyoming is causing slow travel along Interstate 25 and U.S. 85 in the eastern part of the state as well as in the far western part of the state.

Wyoming Department of Transportation spokesman Doug McGee says state troopers rerouted traffic off U.S. 85 in southeast Wyoming because it was so congested Monday afternoon.

McGee says that while the going is slow, traffic is at least moving and he hoped motorists would remain patient.

McGee says large numbers of eclipse watchers descended on the state from the west, south and the east. The northern part of the state wasn't as bad off.
