One lane of alternating traffic will be open on CO 145 north of Dolores as CDOT continues to work to reconstruct the road following last week’s rock fall.

Crews blasted a 2 million pound boulder on the road into smaller pieces to clear the road. The second boulder, weighing more than 8 million pounds remains just off the side of the road. 

Crews estimate anyone traveling on CO 145 should expect delays as long as an hour during the emergency project.
