Intersection Improvements Project on CO 66 to begin Oct. 16

Travel Advisory

Oct. 6, 2023 - Region 4 - Traffic impacts expected for work in Weld County

Weld County — The Colorado Department of Transportation will begin an intersection improvement project on Oct. 16.

Work will occur along CO 66 just outside of Longmont and adjacent to the Town of Mead in Weld County. This intersection improvement project will take place at two different intersections. The first intersection is at CO 66 and Weld County Road 7 near Mile Point 42. The second intersection is at CO 66 and Weld County Road 13 (Colorado Blvd) near MP 45.

Weekly updates will be provided and all real-time closure information will be posted to CDOT has selected Brannan Sand & Gravel as the prime contractor for the project.

The traffic signal systems will be replaced at both intersections. Work will also consist of an asphalt overlay at the WCR 7 intersection only.

Intersection improvement projects have many significant benefits such as upgraded signal systems with integration to other intersections in the CO 66 corridor to improve traffic flow for motorists. Upgraded pavement markings at intersections provide for better visibility.

Travel Impacts

Daytime work hours range from Monday through Friday from 8 a.m. to 5 p.m. Motorists should plan for potential delays due to shoulder and turn lane closures. Existing eastbound and westbound lanes will remain open during day working hours.

Sunday through Thursday nights from 9 p.m. to 5 a.m. Motorists should plan for 15-minute delays due to alternating single-lane closures for milling and paving operations.

There will be a lane width restriction of 12 feet and the speed limit will be reduced to 50 MPH through the work zone. The project is expected to last until the end of March 2024.
