Construction on the East Side of US Highway 285 in the Town of Antonito Being Finalized Next Week

July 31, 2015 - Southwestern Colorado/CDOT Region 5 - ANTONITO, CO – Crews with Concrete Works of Colorado, in conjunction with the Colorado Department of Transportation (CDOT) and Robins Construction, will finalize concrete and asphalt tie-ins on the east side of US Highway 285 in the town of Antonito.

Then, starting on Monday, August 10, traffic lanes will shift to the newly paved section in preparation for the reconstruction of the west side from 8th to 12th Avenues. This will begin Phase IV of the project.

For next week, travelers should anticipate intermittent one-lane closures on US Highway 285. All intersections on the east side will also be closed with business access at both 5th and 8th Avenues. The concrete reconstruction project is part of a $7.8 million plan to improve drainage in the area plus subgrade surface damage created by heavy truck traffic.

*This state-local partnership project will receive funding from RAMP, Responsible Acceleration of Maintenance and Partnerships towards the approximately $2.7 million in drainage improvements. RAMP is better coordinating project expenditures and available funding. Under the RAMP program, CDOT will fund multi-year and partnership projects based on year of expenditure, rather than saving for the full amount of a project before construction begins.
