CHEYENNE, Wyo. — As of 9:13 a.m., ground blizzards caused visibility to drop to zero, leading to total lane blockage on Interstate 80 between mile markers 270 and 277. The Wyoming Department of Transportation has enacted closures on I-80 and US 30/287 between Rawlins and Laramie, with rolling closures extending to areas between Laramie and Cheyenne and Rock Springs and Rawlins.
Due to extreme blowover risk, WYDOT has closed sections of I-25 / US 87 in both directions north of Cheyenne to light and high-profile vehicles. Restrictions are in place for all high-profile vehicles under specific gross vehicle weight thresholds. Despite dry conditions, strong winds have heightened the risk, necessitating these measures.
WYDOT urges travelers to be patient as crews, wreckers and first responders work diligently to clear the wrecks caused by the ground blizzards. The agency emphasizes the importance of avoiding parking on roadways, which can delay efforts to reopen the roads. Estimated reopening times for closures due to rolling closures and extreme blowover risks range from four to six hours.
