Live road conditions (CDOT COtrip)

COtrip is the official Colorado Department of Transportation source for closures, incidents and plow activity. Check it the morning you travel β€” mountain conditions change hourly.

Mountain passes, season by season

  • Grand Mesa Scenic Byway (Hwy 65)

    Snow-packed Nov–Apr

    Plowed but rarely dry in winter. The climb from Mesa gains 5,000 ft β€” check the top, not the bottom, before heading up.

  • I-70 Glenwood Canyon

    Rockfall & flash-flood closures Jul–Sep

    Closes with little warning during storms. The detour is long, so check COtrip before Rifle, not after.

  • Douglas Pass (Hwy 139)

    Ice & slides Nov–Mar

    Steep switchbacks, no services and thin cell coverage. Fill the tank in Loma or Rangely.

  • McClure & Kebler Pass

    Kebler closes with first heavy snow

    Kebler is gravel and unmaintained in winter. McClure stays open but gets slick above Redstone.

  • Monarch Pass (US 50)

    Traction law common Oct–May

    The east-side route to Denver. Watch the wind β€” high-profile vehicles get closed out first.

Local driving tips

Elevation changes everything

The valley floor sits at 4,500 ft and the Grand Mesa tops 10,000 ft. Expect a 20Β°F swing and afternoon thunderstorms up top in summer.

Traction law season

From September 1 to May 31 on I-70, you need snow tires, all-weather tires with 3/16" tread, or chains. Fines apply if you block the road without them.

Pack the car

Water, a blanket, snacks, a phone charger and a paper map. Cell service drops out on Douglas Pass, Glade Park and much of the Grand Mesa.

Watch for wildlife at dusk

Deer and elk cross Hwy 65, Monument Road and 141 at dawn and dusk. Slow down through the marked corridors β€” one animal usually means several.

Know the road? Now plan the day.

Build a stop-by-stop route with coffee, restrooms, the main event and dinner on the way home.
