Interstate 25 has reopened in both directions from Wellington to the Wyoming state line after crews cleared multiple crashes on Monday afternoon.
The major highway reopened just after 2 p.m., the Colorado Department of Transportation said.
In one crash, the Colorado State Patrol said a driver ran into a patrol car while the trooper was investigating a previous accident. The trooper was not hurt.
Blowing snow and slick, snow-packed roads created hazardous conditions.
