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.
In 2020, FHU advanced the NEPA re-Evaluation and final; extensive subsurface utility engineering investigation occurred. Additionally, several coordination meetings were held with CDOT and the Southeast Metro Stormwater Authority (SEMSWA) to evaluate various design refinements to Lee Gulch to meet SEMSWA criteria and accommodate the proposed widening and reconstruction project. The consultant also substantial completed the temporary traffic signal plans, as we hope to install a new traffic signal at the County Line Road / Clarkson Intersection in summer 2021.
In 2021, we plan to advance final design, initiate right-of-way acquisition so that we can move forward with utility relocations in late 2021 and all of 2022.
