County Line Road Improvement Project between University and Broadway
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 and these sections will be completely reconstructed. This project includes adding a new traffic signal at the Clarkson Street / County Line Road intersection and providing 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.
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. This project is estimated to cost $20 million to construct, and construction is anticipated to begin in late 2022 or early 2023. 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). Additionally, these three local agencies are paying for the pre-construction costs, which include final design, relocating utilities, right-of-way acquisition, and drainage improvements.
