Curb Ramp & Pedestrian Improvements in Adams, Arapahoe, Broomfield, Denver & Jefferson Counties

Project Facts

  • Cost: $1.2 million
  • Contractor: NORAA Concrete Construction Corporation
  • Timeline: TBA
  • Location: various counties and municipalities across the Denver metro area

Crews will be replacing curb ramps at intersections such as this one at Belleview and Windemere in Littleton.

Starting Aug. 5, crews will upgrade 118 curb ramps at multiple locations across the Denver Metro area to meet new Americans with Disabilities (ADA) compliance guidelines. Work will be performed with minimal impact to travelers.

This project is part of CDOT's four-year statewide $85 million initiative to upgrade curb ramps to meet new ADA compliance guidelines. The replacement or upgrade of curb ramps at key intersections constitutes major infrastructure improvements across the region, and will:

  • increase the safety, accessibility, and accommodation of residents, patrons of businesses, and visitors.
  • Full access to private driveways and businesses is being maintained during the period of construction.
  • The upgraded ramps will be wider, sloped for easier access by the public, and finished with a slip-resistant texture for additional safety in all weather conditions.
  • The materials used in their construction are fast drying which will expedite pedestrian access upon completion.
