Map: Wintry conditions lead to traction law, closures in Colorado's mountains

A snowstorm the day after Labor Day led to road closures and travel advisories in the mountains of Colorado.

COLORADO, USA — The calendar still says summer, but conditions in Colorado’s mountains were decidedly wintry Tuesday, leading to closures and warnings at multiple high mountain passes.

A cold front caused a nearly 60-degree temperature swing in the state, as temperatures in the 90s on Labor Day gave way to the 30s on Tuesday morning.

While the precipitation had yet to stick to the pavement in the Denver metro area, it was a different story in the mountains. 

Here’s a look at road closures and travel advisories across the state.

Traction laws

Passenger vehicles are required to either have snow tires, use chains/alternative traction devices, or be a 4WD/AWD vehicle on several highways throughout the mountain corridor Tuesday night. 

These include: 

  • I-70 between Vail and Copper Mountain 
  • I-70 between Bakerville and Silverthorne
  • I-70 between C-470 and Idaho Springs
  • US 285 between Pine Junction and Morrison
  • Loveland Pass (US 6)
  • Monarch Pass (US 50)
  • Kenosha Pass (US 285)

Closures

While there were several closures of mountain passes and a section of I-70 throughout the day Tuesday due to crashes and adverse weather conditions, all major highways are currently open as of 7:30 p.m. Tuesday night.
