Crystal Valley Interchange


Construction of a new interchange at Interstate 25 and Crystal Valley Parkway is the Town’s No. 1 transportation priority.

The interchange has been envisioned since the 1980s, and the need for it has grown recently. Projections based on historical growth rates show southbound traffic exiting at the Plum Creek Parkway interchange is likely to queue back to the Wolfebsberger Road/Plum Creek Parkway interchange if a new exit is not built further south.

Located about 2.5 miles south of the Plum Creek Parkway interchange, the Crystal Valley interchange will connect Crystal Valley Parkway on the east side of I-25 to Territorial Road on the west side. As part of the project, the East and West I-25 Frontage Roads will be relocated in the area of the interchange.

The project is focused on accomplishing these objectives:

  • Improving operations and safety along I-25 within Town limits by reducing congestion at the Plum Creek Parkway interchange
  • Improving emergency response to incidents in the south area of Town
  • Providing direct access to I-25 for a growing population
  • Enhancing the local roadway network by providing a continuous east-west through-route across I-25
  • Improving safety by eliminating one at-grade railroad crossing
  • Increasing economic sustainability by providing for adjacent business development

Project funding

Construction of the interchange and relocated frontage roads is expected to cost more than $70 million.

The Town in its 2020-2024 Balanced Financial Plan committed to setting aside $20 million in resources toward the interchange project by 2023.

Funding from past and future private development, as well as from intergovernmental partners, will be needed to get the work underway. The Town is seeking funding to make the project possible in the near term.

Progress to date

An environmental assessment and record of decision were completed in 2004; an updated environmental assessment is needed, along with an interchange access request.

Right of way acquisition is ongoing, and the rough layout of the interchange is complete. Design work is expected to resume in 2021.

Construction of the interchange is anticipated to take a minimum of 24 months. Coordination with the Colorado Department of Transportation and Federal Highway Administration, as well as with BNSF Railway, the U.S. Fish and Wildlife Service and the U.S. Army Corps of Engineers, will be needed.
