US 36 Curb Ramp Replacements

About the Project

This project will upgrade various curb ramps throughout Boulder County, specifically along US 36 and CO 7 in the Town of Lyons and US 36 in the City of Boulder. This project will improve existing curb ramps, pedestrian push buttons and signals, gutters and sidewalks so they are safer and more accessible for pedestrians and people who depend on mobility devices to travel.

Work will begin on 11 curb ramps in Lyons and is expected to take place through the end of December 2025. Afterwards, crews will move east to complete 24 curb ramps in Boulder. Each curb ramp is expected to take approximately three to four days to upgrade and some may occur simultaneously.

Project Locations:

  • CO 7 and Broadway (US 36-Z)
  • CO 7 and Railroad Avenue/Park Drive
  • CO 7 and Prospect Street
  • CO 7 and Meily Street
