Colorado State Highway 119 is closed in both directions between 3rd Street (Nederland) and 3rd Street (Boulder) from Mile Point 26 to Mile Point 41. This includes all of Boulder Canyon. The closure is due to crashes and safety concerns. There is no expected reopening time.

DENVER, COLORADO | 1:55 PM MST  The Colorado Department of Transportation (CDOT) has announced the immediate closure of Interstate 70 just west of Denver, spanning from US 6 / 6th Avenue to C-470 in Golden, due to severe safety concerns prompted by an ongoing winter storm.

The closure, reported at 1:48 PM MST, is part of CDOT’s response to the hazardous conditions brought on by heavy snowfall that began Saturday morning. With no expected reopening time available, travelers are advised to expect significant delays and seek alternative routes.

In addition to the I-70 closure, CDOT has planned a safety closure of US 40 Berthoud Pass, starting from 11 p.m. Saturday (2/3) to 5:30 a.m. Sunday (2/4). This preemptive measure will allow crews to perform necessary winter maintenance operations amid the storm, which has already delivered substantial snowfall across the state, and to manage the risks posed by heavy snow and low visibility.

Storm Impact

The Denver metro area, particularly its south and west sides, is experiencing the brunt of the storm, with forecasts predicting six inches of snow or more. The snowfall, characterized by its heavy and wet nature due to mild temperatures and a high water content, is expected to intensify through the afternoon, posing challenges for shovelers and travelers alike.

Snowfall Totals

As of 10:15 a.m. Saturday, the National Weather Service reported significant snowfall across Colorado, with Skyway receiving 14.5 inches, followed closely by Telluride at 13 inches, and Hayden with 10.5 inches. The widespread nature of the storm has affected both high-altitude locations and metro areas, underscoring the storm’s severity and wide reach.

Safety Tips for Travelers

With the winter storm continuing to impact road conditions and visibility, CDOT urges residents and travelers to heed the following safety advice:

  • Avoid Unnecessary Travel: Stay off the roads during heavy snowfall unless absolutely necessary.
  • Winter Driving Kit: Keep a winter driving kit in your vehicle, including blankets, water, a flashlight, a shovel, and sand or cat litter for traction.
  • Stay Informed: Monitor local news and the Colorado Department of Transportation website for updates on road conditions and closures.
  • Vehicle Preparation: Ensure your vehicle is winter-ready with adequate tire tread, antifreeze levels, and a full tank of gas.
  • Drive Cautiously: Reduce speed, increase following distance, and use chains or snow tires when advised.
  • Plan for Delays: With closures and maintenance work underway, plan for extra travel time or consider postponing non-essential trips.


CDOT’s proactive measures, including road closures and maintenance operations, are aimed at ensuring the safety of all Colorado residents and visitors during this significant winter weather event. The department appreciates the public’s patience and cooperation as they work to manage the storm’s impacts and restore safe travel conditions.
