The lines of traffic that snarled eclipse viewers heading north into Casper on Monday morning are snaking their way back down south.
Vehicles are creeping along highways across the state once again, with bumper-to-bumper traffic on highways from 220 outside Casper to U.S. 18/20 near Lusk.
Traffic counts in Wyoming showed a 27 percent increase by mid-morning, which is more than 217,000 vehicles compared to the five-year average for the third Sunday in August, according to the Wyoming Department of Transportation. The bulk of the increases are in the central, northwestern, western and southern parts of the state.
The largest county increases on Sunday were Laramie County with almost 45,000, Teton County with more than 33,000 and Natrona County with more than 11,000.
Lines of cars and trucks began forming around 3 a.m. on Interstate 25 near Cheyenne and came to a near stop before 7:30 a.m. U.S. Highway 85 north of Cheyenne is also seeing heavy congestion.
The Department urged people to use alternative routes, if possible.
Interstate pull-outs on Interstate 25 between Glenrock and Casper were completely full. On and off ramps were jammed.
Skies were clear in Casper for the eclipse, and the tens of thousands who arrived for the celestial show were not disappointed.
