Closed every winter — typically mid-to-late November through late May — with gates at Lincoln Creek Road on the west side and Graham Gulch on the east. CDOT also bans any vehicle (or vehicle-plus-trailer combination) over 35 ft at any time, year-round, due to the narrow, winding road. Both are firm rules, not general caution.

Planning the drive

The pass climbs 84 counted bends and 7 switchbacks over 36 miles to the Continental Divide at 12,095 ft — our own measured high point came back at 12,097 ft, essentially exact. The west side hairpins are the tightest part: well under two lanes wide in places, with a rock wall on one side and a drop on the other, and little sightline to see oncoming traffic before you're committed to the turn. CDOT: Independence Pass travel information

Two firm rules, not general caution: CDOT bans any vehicle or vehicle-plus-trailer combination over 35 ft at any time, year-round, and the pass closes completely every winter — typically mid-to-late November through late May, with the exact dates set by snowpack each year rather than a fixed calendar. Check current status before planning a trip near either end of the season.

Unverified

Check posted signs along the road.

OpenStreetMap tags this route between 25 and 55 mph depending on the section (town streets in Aspen vs. open highway), but this project does not treat OSM tags alone as a verified source. Follow posted signs.

Posted signs always govern. How speed evidence is handled.
