One-Lane Closures on US Highway 285 in Antonito to Remain in Place for the Next Two Weeks

May 18, 2015 - Southwestern Colorado/CDOT Region 5 - Wide load restrictions begin today, May 18.

ANTONITO, CO – Crews from the Colorado Department of Transportation (CDOT) and contractor Concrete Works of Colorado will continue work on the storm water drainage system being installed on the west side of US Highway 285 in the town of Antonito. For the next two weeks, one-lane closures will be in place with brief, intermittent full lane closures at times. Correcting subgrade and roadway surface damage between 2nd and 12th avenues while concurrently improving drainage is the goal of the $7.8 million concrete reconstruction project. Completion is slated for mid-October and is partially funded through a RAMP* partnership between the Colorado Department of Transportation (CDOT) and the town of Antonito.

PROJECT SCHEDULE & IMPACTS 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 work possible.

Impacts are as follows for the week of May 18th: 

  • US 285 will have a one-lane closure with brief, intermittent full closures

  • Sidewalk and parking lanes will be closed on the west side from 2nd to 8th avenues

  • Starting today, May 18, a 10-foot width restriction will be in place 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.
