Press Release

Today, Congressman Ken Buck (R-Colo.) announced a $5.4 million grant to begin construction of the Crystal Valley Interchange project. This Better Utilizing Investment to Leverage Development (BUILD) Grant will fund critical upgrades to the I-25 corridor running through Castle Rock that will enhance highway operations, alleviate standing safety concerns, and address several traffic-related issues tied to I-25 Gap construction. This Douglas County project has been a longtime priority for Congressman Buck, who has conducted multiple calls and sent numerous letters of support to Department of Transportation officials.


Congressman Ken Buck (R-Colo.): 

“I am proud to announce that the Department of Transportation is granting $5.4 million to begin constructing the Crystal Valley Interchange, an important project for the rapidly growing, vibrant suburbs of the Denver Metro area. This project has been a longtime priority of mine and this BUILD grant will provide necessary funds to improve the safety of the community and further meet Douglas County residents’ needs,” Rep. Buck said.

U.S. Secretary of Transportation Elaine L. Chao:

“This Administration is making significant investments in infrastructure, and this $1 billion in BUILD grants will repair, rebuild, and revitalize transportation systems across America,” Secretary Chao said.


  • Congressman Ken Buck has been a longtime proponent of the Crystal Valley Interchange project, conducting multiple calls and sending numerous letters (linked here and here) to Department of Transportation officials advocating for the project.
  • This grant will fund pre-construction activities and right of way acquisition associated with the construction of the Crystal Valley Parkway Interchange. The project will re-evaluate the previously approved Environmental Assessment, complete the final design of the interchange, and acquire any necessary right-of-way to construct the interchange and associated roadway improvements. The project to eventually be completed includes a new interchange on I-25 at Douglas Lane, five new miles of roadway, and relocation of the existing frontage road to eliminate four at- grade unprotected railroad crossings.
