About the Project:

The Colorado Department of Transportation and contracting partner Sturgeon Electric will begin signal improvements on US
Highway 287 on May 9. The project will take place on US 287 at Mountain View Avenue and 6th Avenue.

Work will include the removal and installation of traffic signal equipment, poles, mast arms, pedestrian push buttons, signing
and vehicle detection upgrades. Crews will also install Americans with Disabilities Act (ADA) compliant curb ramps. The new ramps will be in compliance with the Public Right of Way Accessibility Guidelines (PROWAG) requirements and will provide functional accessibility to all travelers using our state and US highways.

Project Benefits

Traffic signals are a vital part of controlling traffic in a safe and efficient manner by providing regulated movement. Vehicle
detection will reduce unnecessary delays and stops at the intersection while improving travel times and increasing the
amount of traffic that an intersection can handle.

    completion date of July 2022.
