Updated September 2019 –Construction on US 85 is anticipated to begin the summer/fall of 2019. The project team is finalizing plans, and working with utility companies to identify a schedule and complete relocations prior to construction. The Right-of-Way acquisition is nearing completion (90%) with only a few parcels left to be acquired. The project limits are from Highlands Ranch Parkway to Dad Clark Gulch (about ¼ mile north of County Line Road).
US 85 Corridor Improvements
- US 85 widening Highlands Ranch Parkway to Dad Clark Gulch (1,200 ft north of County Line Rd), combined with reconstructing the US 8 / C-470 interchange and widening US 85 to three thru lanes plus auxiliary lanes in each direction between Highlands Ranch Parkway to Dad Clark Gulch, adding bicycle and pedestrian improvements. This $94 Million project will provide additional capacity and a safer more reliable regional transportation network. In 2019, we held a final design review meeting (over 1,200 plan sheets), we acquired over $5 Million in additional right-of-way (as of August 1st, we acquired over 70 parcels – only three parcels remaining), we initiated major utility relocations with Excel Energy, after 15 months of no action, we have re-engaged Century Link on advancing the design of their infrastructure relocation, we are working with the BNSF and Union Pacific Railroads to accommodate the proposed widening, we continue to work closely with CDOT a gain their approval and anticipate bidding this project in spring 2020, with anticipated completion date fall 2022.
- US 85 widening from two to four lanes between Louviers to Sedalia. This project requires full reconstruction of US 85 and CDOT anticipates bidding this $35 Million project in October 2019 and beginning construction in early 2020. Douglas County has been involved in the design and right-of-way phases and is contributing a total of $7 million to advance this project.
- US 85 widening from two to four lanes between SH 67 (Sedalia) to Happy Canyon Road and Daniels Park Road Intersection improvements. The County is partnering with CDOT to improve the US 85 and install a traffic signal at Daniels Park Road Intersection. In 2019, CDOT and the County met with IREA regarding relocating their infrastructure to accommodate the proposed improvements. Additionally, the County met key property owners as part of the right-of-way (ROW) acquisition process, and the County looks to be successful in obtaining some DRCOG federal funding for ROW and design.
- US 85 / Titan Interchange Improvements. Douglas County is working with CDOT to complete the final design and obtain necessary permits in order to widen the northbound on-ramp and restripe Titan over US 85 in order to improve safety and traffic operations. Anticipate construct improvements to begin the fall of 2019.
