Project Update

Updated July 20 2023: Construction is anticipated to begin in early 2024.

Project Duration: About 24 months.


From 2019 to 2022, Douglas County has worked with partners to advance the final design, acquire right-of-way, and prepare utility relocation design for a major water line located within the project area. Denver Regional Council of Governments (DRCOG) selected this project to receive $12.5 million for construction in federal funding through the DRCOG Transportation Improvement Program (TIP) Subregion project selection process. The remaining construction funding is being provided by the City of Littleton ($1 million), the City of Centennial ($5.5 million), and Douglas County ($8 million).

This project will include a new traffic signal at the Clarkson Street / County Line Road intersection, a mill and overlay for the portion of the road within the City of Littleton located between Phillips Avenue and Broadway, as well as adding sidewalks. Construction is anticipated to begin in early 2024.
