CO 257 Resurfacing US 34 Business to Walnut Street

Project completed

About the Project

The CO 257 Resurfacing project improved nearly five miles of highway between US 34 Business (Mile Point 5.6) in Greeley and Walnut Street (MP 10.4) in Windsor. Bridge repairs at MP 7.6, which is approximately two miles north of US Business 34, required a temporary 20-day full closure of CO 257. Intersection improvements at Crossroads Boulevard included adding a second eastbound left turn lane to northbound CO 257. Safety improvements included installing new guardrail, roadside delineators, and rumble strips.
