Signal improvement project to begin in Boulder and Longmont on May 9

News Release

May 3, 2022 - Northern Colorado (Region 4) - Improvements will take place at three locations

BOULDER COUNTY — The Colorado Department of Transportation will begin a signal improvement project May 9 on CO 7 in Boulder and on US 287 in Longmont. Sturgeon Electric is the contractor for this project.

Work will take place on US 287 at Mountain View Avenue and 6th Avenue in Longmont and on CO 7 and Commerce Street/Eisenhower Drive in Boulder. Work will include the removal and installation of traffic signal equipment, poles, mast arms, pedestrian push buttons, signing and vehicle detection upgrades.

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.

Other benefits of the project include the installation of 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 function accessibility to all travelers using our state and US highways.CO 287 Signal Improvement Project Map Image
