2021 Recommended Detour & Alternate Route

Recommended alternate closures Glenwood Canyon

CDOT strongly asks that motorists use the recommended northern alternate route via I-70 – CO 9 – US 40 – CO 13. Westbound motorists from the Denver metro area should exit I-70 at Exit 205 (Silverthorne) and travel north on Colorado Highway 9 towards Kremmling. Travelers will continue west on US Highway 40 and then south on CO 13 to complete the alternate route and return to westbound I-70 at Rifle (Exit 90). Eastbound travelers can detour using the same route in reverse.

Before detouring onto any alternate route, motorists should refer to COtrip.org for the latest road conditions.

NOTE: GPS may show alternate routes but keep in mind, many of the routes are impassable with non-4×4 vehicles (without clearance) and there is NO CELL phone reception on the suggested mountain roadways!
