Plan extra time along US 85 in Highlands Ranch

Two weekend impacts planned as construction continues on major improvements to the corridor

Posted on May 17, 2023 2023News and EventsTransportation


This weekend, crews will work under the Union Pacific Railroad bridge, pictured here, over US 85, as part of Douglas County’s US 85 Widening project.

Driving near US 85 and Highlands Ranch Parkway this weekend? Please plan around two construction-related road impacts.

US 85 Lane Closures
Watch for delays and single lane closures between Norwood and Blakeland drives starting at 10 p.m. Friday, May 19.

These lane closures will allow crews to safely perform roadway and bridge work under the Union Pacific Railroad over US 85. This extended closure will eliminate the need for more than 30 overnight closures as part of the corridor improvements being made by Douglas County and its partners during the US 85 widening and reconstruction project from Highlands Ranch Parkway to north of C-470.

Please give yourself extra time or use alternate routes and pay attention to posted speed limits and signage.

Highlands Ranch Parkway Closure
Highlands Ranch Parkway will be fully closed between Bucknell Drive and US 85 from 8 p.m. Friday, May 19, to 5 a.m. Monday, May 22. (Construction crews will maintain access for first responders.)

The closure will allow crews to safely remove and replace the existing underground utilities beneath Highlands Ranch Parkway along US 85. US 85 will not be impacted during this closure.

If weather conditions do not allow this work to take place as originally scheduled, crews will conduct this work at a later date.

Please watch for crews, heed the speed limit, and avoid distracted driving in the work zone.
