Project Update

Update June 2022: Construction is anticipated to begin in early 2023.


In August 2019, the Denver Regional Council of Governments (DRCOG) selected this project to receive $10 million for construction in federal funding through the DRCOG Transportation Improvement Program (TIP) Subregion project selection process. The other portion of construction funding is being provided by the City of Littleton ($1 million), City of Centennial ($4.5 million), and Douglas County ($4.5 million). The total estimated project cost is $20 million.

In April 2020, Douglas County contracted with Felsburg Holt Ulliveg (FHU) to complete final design for the last segment of County Line Road that needs to be widened from two to four through lanes for complete reconstruction. 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 2023.
