US 85 Corridor Improvements

Updated August 2021

 

US 85 widening from four to six lanes from Highlands Ranch Parkway to Dad Clark Gulch (located about 1,200-feet north of County Line Road)

As of August 2021, all right-of-way (ROW) acquisition has been completed, with the exception of four outstanding easements.  The final design is substantially complete, and staff is waiting on final approvals from CDOT. Construction is scheduled to begin in spring 2022 and take approximately 30 months to complete.  This project involves widening and reconstructing approximately 2.5 miles of US 85 from Highlands Ranch Parkway to Dad Clark Gulch.

The total project is estimated to cost over $100 million. The project was selected to receive approximately $26.2 million federal funding via the Denver Regional Council of Governments (DRCOG) through the Transportation Improvement Program (TIP) project selection process.  Additionally, CDOT will be contributing $7.6 million while the remainder of the project is Douglas County’s responsibility (approximately $68 million needs to be allocated for environmental clearances, preliminary and final design, right-of-way acquisition, utility relocations, and for construction and construction engineering services).  A portion of Douglas County’s contribution is funded by developers in the Chatfield Basin, which increases as development occurs.

US 85 widening from two to four lanes from SH 67 (Sedalia) to Daniels Park Road  

The County is partnering with CDOT to advance final design and ROW acquisition associated with reconstructing and widening US 85 to four lanes from Sedalia (SH 67) to Daniels Park Road.  However, CDOT has not identified funding for constructing this segment in their current 4-year pipeline list of priority projects.  August 2021, the County executed an IGA with CDOT regarding funding for final design and ROW acquisition, which includes $1,050,000 in federal funds made available for this project through the Denver Regional Council of Governments (DRCOG) Transportation Improvement Program (TIP) Subregional Project Selection Process; and Douglas County has agreed to contribute $1 million and CDOT is contributing about $2.6 million. For more information about this project contact Josh Breedlove, CDOT Resident Engineer at [email protected]
