GUNNISON COUNTY, Colo. — Highway 133 will be closed until at least Saturday after a rock slide dropped more than 100 tons of debris on the highway, causing extensive damage, the Colorado Department of Transportation said.
The slide happened about 8:15 a.m. Wednesday on the north end of Paonia Reservoir. Both lanes of the highway were covered with large boulders and other debris.
There was damage to the roadway surface and adjacent concrete barrier. No vehicles were involved and no injuries were reported, CDOT said.
CDOT crews and a geohazard contractor are working to determine the extent of rock scaling operations that are needed to mitigate any future slides.
The highway is closed from the Collbran turnoff (mile marker 36) to the Kebler Pass turnoff (mile marker 24). The slide happened at about mile marker 29.5.
Crews are hoping to reopen the highway on Saturday. More than 1,100 vehicles use the road each day.
CDOT said drivers should use Interstate 70 to the north and U.S. 50 to the south as detours, which will add about three additional hours to trips.
Highway 133 goes between Hotchkiss and Carbondale through Paonia State Park.
