Work will take place in Rio Blanco and Moffat counties

May 5, 2021 - Northwestern Colorado

Crews prepare for highway improvements on CO 64 and US 40 


MOFFAT AND RIO BLANCO COUNTIES — The Colorado Department of Transportation will begin a resurfacing project on US Highway 40 and Colorado Highway 64 in May. Work will address two sections of distressed highway in rural Northwest Colorado. Roadways in the communities of Rangely and Dinosaur show severe cracking and are beginning to fail. Work along US 40 will take place in and near the community of Dinosaur, Mile Points 0 – 7. Work on CO 64 will be in and near Rangely, MP 20-28. Work will consist of overlay on both roadways, pavement markings bringing guardrails up to the new standards.
