Overnight full closures of C-470 and US 85 interchange for bridge construction

Posted on June 21, 2024 2024Transportation


Expect detours on C-470 and US 85 in Highlands Ranch overnight Tuesday, June 25, Wednesday, June 26 and Thursday, June 27

Give yourself extra time to drive C-470 or US 85 (Santa Fe Drive) in Highlands Ranch overnight next week. Several detours will be in place around the interchange of C-470 and US 85 nightly from 8 p.m. to 5:30 a.m. Tuesday, June 25, through Thursday, June 27.

These closures are necessary for driver and worker safety during overhead bridge work. During these closures, crews will use a crane to lift and place 20 bridge beams, called girders, to form the eastern portion of the 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.

Please take an alternate route or plan extra time. Pay close attention to posted speed limits and signage. Watch for crews.

Here are the planned detours:

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.
