Treacherous driving conditions have led to multiple closures with more to come Thursday

Winter Travel Alert

March 14, 2024 - Statewide - Motorists urged to avoid travel if possible

Statewide- Several highways across the Denver metro area and high country are closed due to adverse conditions and crashes. Road conditions vary, but most highways are snowpacked and slushy making driving conditions difficult.

Keeping the roads open as much as possible will be an all-hands-on-deck effort. CDOT urged drivers to stay off the road when possible during heavy periods of snow and to make sure that vehicles venturing into the snow are equipped for the conditions. For example, numerous instances of jack-knifed semi trucks, many without chains, have led to numerous closures on key thoroughfares like I-70. If travelers must head out, be sure to maintain slower speeds, keep plenty of room between you and the vehicle ahead and use extreme caution. There may be a lull in weather early this morning in the Denver metro area, but motorists should be warned that snow conditions are expected to pick back up later in the morning.

Below are the closures that are currently in place as of 8 a.m.:

  • I-70 in both directions between Morrison and Silverthorne because of adverse conditions and semi-truck crashes due to lack of chains.
  • US 285 just south of C-470 is closed due to a jackknifed semi truck.
  • Highway 119 is closed due to adverse conditions. Power outages have been reported.
  • US 40 Berthoud Pass and US 6 Loveland Pass are closed due to adverse conditions, avalanche recovery after a natural slide occurred overnight and additional
  • winter operations will be necessary to make sure that the roads are safe to reopen.
  • US 40/I-70 Frontage Road is closed.

I-25 between Castle Rock and northern Colorado Springs and roads in the Palmer Divide communities are particularly treacherous and have received over 10” of snow, making driving conditions very difficult. The winter storm will continue throughout the day and roads may become worse, especially as more folks take to the roads. The storm is tracking as forecasted. Friday morning ski traffic will be affected.

Winter Travel Tips for Motorists

  • Avoid or limit driving during the brunt of the storm on Thursday.  
  • Work from home if you can.
  • If you plan to travel, know before you go by checking out the latest weather conditions and visiting for road conditions (see info sources below).
  • Make sure your vehicle is winter ready with the appropriate tires for the weather and have a snow emergency kit.
  • Once you are out on the road, take it slow, no sudden stops and leave plenty of following distance.
  • Give plows space! Stay back three to four car lengths from snow plows.

Safety Closures

A safety closure is a precaution taken during inclement weather to reduce the probability of traffic incidents, increased congestion or other safety-related factors. During a safety closure, traffic may be stopped on the interstate, turned around or directed to an exit. Safety closures help decrease delay times, and, above all, keep travelers safe.

Chain & Traction Laws

When weather conditions warrant, CDOT will activate the Traction Law. If weather conditions deteriorate, CDOT will activate Chain Laws for passenger and commercial vehicles. Motorists will be alerted to an active Traction or Chain Law by highway signage, and traffic/roadway condition alerts.
