CDOT will permanently close I-25 East Frontage Road access to WCR 34 on Jan. 5

Travel Advisory

Weld County - The Colorado Department of Transportation will permanently close the I-25 East Frontage Road access to Weld County Road 34, in Mead, on Monday, Jan. 5, at 5 a.m. Closing frontage road access to WCR 34 is required for crews to extend the North Creek Box Culvert as part of the I-25 North Express Lanes project.

This closure is part of CDOT's continued coordination with the Town of Mead and Weld County, who are building a 2-mile portion of High Plains Boulevard between Weld County Road 32 and Weld County Road 36. Once opened, (projected summer 2026), traffic that previously used the frontage road will use High Plains Boulevard, and the frontage road use will transition to private property and utility access only.

As shown on the map, local motorists will be able to access their properties between WCR 34 and WCR 36, but thru traffic will not be allowed. Similarly, local motorists will be able to access their properties between WCR 34 and WCR 32, but no thru traffic will be allowed.

Starting late January, in preparation for accommodating the I-25 northbound lane widening and the frontage roadway transition, construction crews will begin to reduce the asphalt roadway width on isolated sections of the frontage road, from Mulligan Street (northeast quadrant of Colorado Highway 66 and I-25) to Colorado Highway 56.

During construction, the frontage road will be closed south of WCR 32 so crews can complete I-25 widening and drainage work. Viable detour routes and speed limit reductions will be posted. Please drive carefully through the work zones and reduced roadway sections.

Images show detour area maps with access changes to the I-25 E. Frontage Road from WCR 34 to WCR 36 as well as CO 66 to WCR 34.
