Beginning at 7 p.m. on Wednesday, Oct. 26, southbound US 85 (Santa Fe Drive) access to eastbound C-470 will temporarily close for bridge reconstruction at the C-470 and US 85 interchange. To detour, motorists can use the southbound US 85 flyover or County Line Road to Lucent Boulevard to access eastbound C-470.  This closure will be in place through 2023.

Traffic Impacts on C-470
Motorists can expect overnight lane closures on C-470 from 9 p.m. to 5:30 a.m.

Traffic Impacts on US 85 (Santa Fe Drive)
Daytime working hours on US 85 are 7 a.m. to 7 p.m., with daytime lane closures occurring during non-peak travel times. Motorists can expect overnight lane closures on US 85 from

Project Information

This project will widen and reconstruct 2.5 miles of US 85 from Highlands Ranch Parkway to C-470 from four to six lanes. The project also includes the reconstruction of three intersections to improve traffic flow: southbound US 85 to eastbound Town Center Drive, southbound US 85 to eastbound Highlands Ranch Parkway and northbound US 85 to westbound C-470.

Multimodal improvements include bus stop enhancements, a new shared-use path for bicyclists and pedestrians on the east side of US 85, a below-grade crossing for the C-470 Trail at US 85, a below-grade crossing for the High Line Canal Trail at US 85, and a new pedestrian link from the Wolhurst Senior Community to the C-470 Trail.

Construction activities will require reduced speeds, lane closures, and various full closures.
