Highway 145 reopened with single lane

Colorado Highway 145 about 12 miles north of Dolores is back open with single-lane alternating traffic, according to the Colorado Department of Transportation.

The highway was closed Friday and Saturday after two giant boulders fell and destroyed part of the highway.

Both lanes of traffic will encounter portable stoplight signals to control traffic flow at the rockslide site.

The temporary road is dirt, so travelers are advised to slow down and use extreme caution through the area.

Crews will begin work today to rebuild the section of damaged highway. Motorists will have periodic and lengthy delays of up to a full hour while the road is being reconstructed.

CDOT officials estimate the reconstruction project will take one to two weeks to complete.

On Sunday, crews blasted one of the massive boulders. The rock was shattered into small chunks and fragments to be removed from the roadway. The estimated size of the boulder was 2.5 million pounds.

A second and larger house-sized boulder estimated at 8.5 million pounds created an 8-foot trench across both lanes and landed on the east side of the road away from the highway. CDOT officials have no current plans to remove that boulder.
