ADD TO CALENDAR

Safety improvements are coming to the Happy Canyon Road and Interstate 25 (I-25) interchange in Castle Pines. The improvements, consistent with the City of Castle Pines Comprehensive Plan and Transportation Master Plan guidance, will improve traffic operations, connectivity, and regional mobility, as well as support local community growth. This project also aligns with the Board of Douglas County Commissioners’ Core Priority to provide a reliable multi-modal transportation network. This project is identified in the County’s 2040 Transportation Master Plan, and it’s one of the County’s priority projects as identified in the County’s current 5-Year Capital Improvement Program.

Join the project team for a public open house on Thursday, June 4, from 4:30-6:00 p.m. at the Castle Pines Library Event Hall (360 Village Square Drive) to learn about upcoming construction. No formal presentation will take place. You are encouraged to come and go during the event as your schedule allows. During the open house, you’ll have a chance to:

  • Review information about the new interchange design
  • Learn about the project timeline and anticipated traffic impacts
  • Ask the project team questions
