For many years Douglas County and the Colorado Department of Transportation (CDOT) have been making improvements to the US 85 Corridor based on the 2002 South I-25/US 85 Environmental Impact Statement (EIS) and Revised Record of Decision (ROD). As additional residential and commercial growth occurs in the northwest portion of the county, further studies are needed to identify what transportation improvements are necessary to support the development. Douglas County has secured additional funds to continue this work and is sponsoring two important studies of US 85. The two studies are separate but will be closely coordinated at each step in the process to allow citizen and stakeholder input. Ideally, these efforts will assist the County and other agencies in identifying issues of importance in order to implement the highest-priority near-term improvements as soon as possible.
- The PEL Study will update recommended improvements from approximately State Highway 67 (SH 67) in Sedalia to ½ mile north of C-470.
- The Highlands Ranch Parkway to C-470 Project will update the 2002 ROD to reanalyze impacts and begin design of recommended improvements for US 85 from Highlands Ranch Parkway to C-470.
