Weekend-long closures of C-470 ramps at US 85 for bridge and roadway construction

Expect detours on C-470 ramps at US 85 in Highlands Ranch first two weekends in November

Posted on October 30, 2023 2023News and EventsTransportation


Ramp Closure Update Nov. 3:
Your access at US 85 and C-470 will be open this weekend. Previously scheduled ramp closures have been postponed due to unresolved utility conflicts. Please stay tuned for updates.

Give yourself extra time to drive C-470 to and from US 85 (Santa Fe Drive) in Highlands Ranch during upcoming weekend-long ramp closures. To ensure driver and worker safety during bridge and ramp reconstruction work, the following closures, requiring detours, will be in place:

During these closures, crews will remove asphalt and pave new asphalt on the on- and off-ramps at C-470 and perform embankment and wall construction to complete a major portion of a new US 85 bridge. The work is a key milestone in the project to widen US 85 from Highlands Ranch Parkway to just north of C-470 and improve traffic flow at several intersections, including this interchange.

Please take an alternate route or plan extra time. Please watch for crews, heed the speed limit, and avoid distracted driving in the work zone.

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

In partnership with the Colorado Department of Transportation, Denver Regional Council of Governments, the Federal Highway Administration, Highlands Ranch Metro District, and Chatfield Basin developers, Douglas County is improving safety and mobility along US 85 from Highlands Ranch Parkway to just north of C-470.
