US 85 Platteville Resurfacing Between CO 60 and CO 66

About the Project:

This project will improve US Highway 85 near Platteville. Over three miles of northbound and southbound US 85 (Mile Points 250.5 – 254.0) will receive a new asphalt surface. The project will also extend the northbound US 85 left-turn lane at Colorado Highway 60, construct intersection safety improvements at Marion Avenue, and upgrade striping and signage throughout the corridor. A center median will be added at Marion Avenue to limit access to right-in, right-out on all approaches except northbound US 85 where left turns will still be possible onto Marion Avenue.
