Construction is anticipated to begin in September 2025.
Project Duration: About 24 months.
Since 2019, 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 $12.582 million (maximum contribution) for construction in federal funding through the DRCOG Transportation Improvement Program (TIP) Subregion project selection process. All the remaining project costs are the local agency responsibilities. Douglas County is partnering with the City of Littleton and the City of Centennial to fund the project. The total construction cost is estimated to be approximately $34 million for budget planning purposes which includes contingency funds, construction costs and consultant engineering costs to provide project management, inspections, and material testing for the project.
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 start in the early Summer of 2025.
