CDOT warns more closures to I-70 in Glenwood Canyon could be coming – The Denver Post

After two consecutive mudslides forced the closure of Interstate 70 across three days in Glenwood Canyon, the Colorado Department of Transportation is warning travelers to be prepared for more closures of the road.

Heavy rains are easily creating flash floods in the area due to the burn scare caused by the Grizzly Creek Fire.

Flash floods, mudslides, rockfalls and other hazards are possible for motorists.

The National Weather Service announced a flash flood advisory for the area on Tuesday. In response, CDOT has closed the Grizzly Creek and Shoshone Power Plant rest areas and the Glenwood Canyon recreation path.

If the NWS upgrades the advisory to a flash flood warning for the Grizzly Creek burn scar, CDOT will close I-70 in Glenwood Canyon and clear the canyon of traffic. Drivers should use the recommended northern alternate route if any closure is expected to last longer than an hour.

That northern detour is as follows: From the Denver metro area or Interstate 25, travel westbound on I-70 to Silverthorne, turn north onto CO 9. In Kremmling, turn onto westbound U.S. Highway 40 towards Steamboat Springs. After reaching Craig, return south via CO 13 towards Rifle. Access to I-70 westbound is at Rifle. From the Western Slope, the directions are in reverse.

That route is nearly 100 miles and three hours longer, taking drivers far into northwest Colorado. Non-commercial motorists are allowed to take Colorado Highway 82 over Independence Pass.

CDOT warned earlier this week against using vehicle navigation applications to look for alternate routes. Many auxiliary roads such as Cottonwood Pass, Hagerman Pass and Eagle/Thomasville Road may not be passable and do not have cell service. Cottonwood Pass is restricted to local traffic only.

Officials also ask that if you are caught in adverse conditions, waiting for the road to clear, not leave your vehicle unless necessary.
