CO 2/CO 88/US 285 Denver Metro ADA Ramps

About the Project:

Project will consists of replacing approximately 207 curb ramps to comply with Federal ADA standards. The project will be built in three phases.

  • Phase 1: 12 miles of US 285 from South Simms to South Clermont streets (Mile Points 252-264)
  • Phase 2: 5 miles of CO 2 from Dickenson Place and Batavia Place (Mile Points 1-6)
  • Phase 3: 4 miles of CO 88 from Boston and South Clinton streets to South Helena Street and Cornerstar Way (Mile Points 17-21)
