Wet, heavy snow creates messy morning commute

The latest on road conditions and traffic alerts from a storm that brought heavy bands of snow to Colorado.

COLORADO, USA — A storm that moved into Colorado overnight has brought heavy, wet snow to many roads Tuesday morning leading to several traffic delays and road closures.

A jackknifed semi-truck closed all lanes of westbound Interstate 70 at Federal Boulevard during the morning commute. Denver police said the road has since reopened.  

Southbound I-25 near Castle Pines was also closed for a time due to wintry conditions and multiple stalled vehicles on the roadway.

Gusty winds and blowing and drifting snow are making for tough traveling conditions along Colorado's higher mountain passes. Locations near Vail, Snowmass and Aspen are expected to see 7 to 14 inches of fresh snow throughout the day. 

Winter Weather Advisories and Winter Storm Warnings are in effect until noon Tuesday for parts of Colorado's central and southern mountains. The storm is expected to move out of Denver and into southeastern Colorado by Tuesday afternoon.  

CDOT crews have nearly nearly 400 plows out working to clear roads around the state.

Chain and traction laws

CDOT urges travelers to be aware of chain and traction law codes before heading out on the roadway:

  • Code 18/Commercial Chain Law: Commercial vehicles and trucks must have chains. Vehicles without chains can often lose traction, causing traffic delays and sometimes road closures. For the safety of the traveling public, it's critical to use chains to be in compliance with Colorado's chain law.
  • Code 15/Passenger Traction Law: All passenger vehicles must have appropriate all-weather tires with 3/16-inch depth. Vehicles must have one of the following: winter tires, tires with mud/snow (M+S) designation, chains or alternative traction devices such as an autosock. 4WD and AWD vehicles must have winter tires or all-weather tires.
  • Code 16/Passenger Chain Law: All passenger vehicles need chains, except for 4WD and AWD vehicles with all-weather tires with 3/16-inch tread depth.
