Curb Ramp Accessibility Initiative


In 2017, CDOT embarked on an $85M effort to bring all curb ramps into alignment with the ADA and PROWAG standards over the next five years. With more than 20,000 curb ramps statewide, CDOT is taking a “worst first” approach to upgrading curb ramps and addressing deficiencies. This approach has been reviewed and vetted by the Colorado Advisory Council for Persons with Disabilities, which provided a letter of support for CDOT's program.
