US Highway 40 is closed both at Berthoud Pass and near Rabbit Ears Pass on the other side of Grand County.
The Colorado Department of Transportation is advising motorists to expect long delays for both closures. The closure on the eastern side of the county is just east of Winter Park, on the western side of Berthoud Pass.
Meanwhile, the closure on the western side of Grand County is between mile marker 136 and Wolford Rec Road, about 4 miles west of Kremmling.
The closures come after a morning snowstorm brought near white-out conditions to Grand County. Additionally, the National Weather Service has extended a winter weather advisory until 8 p.m. Friday to account for hazardous travel conditions.
