US 160/491 South Broadway Reconstruction Complete

May 3, 2013 - PROJECT COMPLETE - CORTEZ – On May 2, the Colorado Department of Transportation issued the final acceptance letter to contractor Lawson Construction, marking the completion of concrete reconstruction and safety improvements on US 160/US 491 in Cortez.

The City of Cortez will conduct landscaping at a later date.

The work began last July and was suspended for the winter; the project resumed in March and had a scheduled completion of late April (a final inspection was conducted on April 23). With a $4.8 million contract, Lawson Construction crews reconstructed the highway with concrete between MP 37 (at the south end of Cortez) and MP 38, tying into the existing concrete pavement on South Broadway. Crews removed the existing asphalt roadway and replaced it with nine inches of concrete pavement.

Other upgrades included a new storm sewer at 7th Street, improvements to intersections, ADA-compliant sidewalks and ramps, and the new signal at the US 160/US 491 intersection. 

Given the poor sub-grade soils and numerous utilities beneath the existing asphalt surface, concrete reconstruction was determined to be the best solution for this stretch of highway. With this reconstruction, future maintenance on this stretch will be minimal and motorists will travel through this area without significant roadwork impacts for decades.
