US Highway 285 Construction Project Moves to Final Phase

September 29, 2015 - Southwestern Colorado/CDOT Region 5 - Town of Antonito, CO – The $7.8 million concrete reconstruction project on US Highway 285 in the town of Antonito is in its final stage of construction.

 The project began in March of this year with the goal of correcting subgrade surface damage created by heavy truck traffic while concurrently improving the drainage system.  

Mid-October is the anticipated completion date. Contractor, Ryan Brasher with Concrete Works of Colorado, explains, “We’re right on target. Everyone’s hard work and the support of the town have allowed us to meet our scheduled timeframe.”

Starting this week, crews with the Colorado Department of Transportation (CDOT) and Concrete Works of Colorado will reopen side street intersections on the west side of the highway with intermittent temporary closures as needed. Parking lanes and sidewalks will remain closed for the week. For more information on Phase 5, please see the diagram below:

PROJECT SCHEDULE & IMPACTS – A 10-foot width restriction will remain in effect 24/7 until the project’s completion in mid-October. Work hours are expected to be from 7:00 a.m. to 7:00 p.m., Monday through Friday, with some weekend and late night or early morning work possible.

Impacts are as follows for the week of September 25:

  • Intersections on the west side will be open with intermittent temporary closures at times

  • 10-foot width restrictions are in place 24/7 until the end of the project in mid-October

*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.
