Highway 285/9 intersection project begins

Project Update

June 13, 2023 - Southeastern Colorado - Project involves road widening to accommodate additional traffic lanes, new signals, and sidewalks

Fairplay — An intersection improvement project is underway at the US 285/CO 9 intersection involving road widening to accommodate additional traffic lanes, new signals, and sidewalks.

The project also is replacing the functionally obsolete and structurally deficient 86-year-old Middle Fork of the South Platte River bridge on US 285, just south of the intersection. Additionally, new curb ramps are being installed at various locations in Fairplay and Alma.

Traffic Impacts

No Lane Closures during the day – 7 a.m. to 6 p.m., Monday through Friday. One lane of traffic will remain open in each direction on US 285 and CO 9. However, drivers should anticipate narrowed and shifting traffic lanes and a reduced speed limit.

Lane closures are scheduled at night, with flaggers alternating one lane of traffic through the work zone during the following hours:

  • Sundays 10 p.m. to 6 a.m. Monday
  • Monday through Thursday – 8 p.m. to 6 a.m.
  • Delays up to 10 minutes can be expected

When complete, the reconstructed intersection and new bridge will improve traffic flow in and out of Fairplay, and increase safety for motorists, pedestrians and bicyclists. New ADA ramps will provide additional accessibility to various locations in Fairplay and Alma.

American Civil Constructors of Littleton is the contractor for the $24.1 million project. It is schedule for completion in fall 2024.
