Travel Advisory

August 15, 2022 - Northwestern Colorado - Glenwood Canyon reopened at 8:20 p.m. Safety closure was in place between exit 116 (Glenwood Springs) and exit 133 (Dotsero).

Glenwood Canyon - The Colorado Department of Transportation has closed Interstate 70 Glenwood Canyon due to a Flash Flood Warning issued for the Grizzly Creek Fire burn scar and Glenwood Canyon. The warning was announced by the National Weather Service at 5:00 p.m. on Monday, August 15. As of 6 p.m., the warning is in effect until 8 p.m. Eastbound and westbound I-70 are closed from Glenwood Springs (exit 116) to Dotsero (exit 133), with a second closure point for westbound traffic at Eagle (exit 140). Eagle County residents will still have access to locations between exits 133 and 140 by using US Highway 6. On the west side of the canyon, motorists continue to have access to Glenwood Springs and the Roaring Fork Valley

A safety closure of I-70 is necessary as part of safety protocol to protect the traveling public from flash floods and mudslides in Glenwood Canyon. Motorists should monitor weather alerts to see when the Flash Flood Warning ends. The safety closure will continue to be in place until the Flash Flood Warning is lifted. The closure may stay in effect if weather conditions are unpredictable or if flash floods occur.

Motorists should use COtrip.org or CDOT’s free COtrip Planner mobile app to plan an alternate route. The northern alternate route on US Highway 40 is recommended for most motorists. The northern alternate route will require approximately 2.5 hours additional travel time to reach your destination, compared to traveling on I-70 through Glenwood Canyon. Westbound motorists from the Denver metro area can reach the northern route via US Highway 40, Colorado Highway 9 or Colorado Highway 131. (When detouring north onto CO 9, motorists should anticipate construction at exit 205 in Silverthorne.) Travelers can then 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). For eastbound I-70 motorists, a traffic control point is in place at eastbound West Rifle (exit 87) to guide motorists to the northern alternate route. 

Before detouring onto any alternate route, motorists should refer to COtrip.org for the latest road conditions. By traveling on the recommended alternate route, motorists can avoid major delays caused by rough roads and other hazards.
