US 85 improvements start Monday south of Platteville

April 27, 2021 - Northeastern Colorado

PLATTEVILLE – The Colorado Department of Transportation will start construction activities on U.S. Highway 85 (Centennial Highway) south of Platteville on Monday. By the end of summer, drivers will enjoy a smoother highway with roadside safety enhancements. 

Over four miles of northbound and southbound US 85 (Mile Points 246 – 250.5) will receive a new asphalt surface. This project will also improve a ditch south of Weld County Road 26, upgrade guardrail, replace bridge railing over Platte Valley Canal, and install new safety enhancements including rumble strips and roadside delineators.

Starting Monday, drivers should expect frequent lane closures on northbound US 85 from 6 a.m. to 5 p.m., Monday through Friday. Rough-riding grooved pavement and uneven lanes will be present during construction. Various mobile construction operations will be used for the work, and the contractor will hold traffic at intersections and driveways while equipment passes through. Speed limit reductions and width restrictions will be in place as needed. 

“CDOT and US 85 Coalition partners including Weld County and the Town of Platteville have long recognized US 85 as a valuable transportation corridor. We are making investments now to improve safety and the driving experience for all users,” said CDOT Regional Transportation Director Heather Paddock. 

Coulson Excavating Company will perform most of the work from May to November and project completion is anticipated in spring 2022. Construction schedules are weather-dependent and subject to change. Weekly updates are available on the project web page.
