Commuters in Weld County can anticipate the return of construction crews this March as work on the US 85 and US 34 interchange resumes, aiming to enhance safety and mobility in the region. The project, managed by the Colorado Department of Transportation (CDOT) and Jalisco International, Inc., targets a June 2025 completion date, and promises improved signage, lane striping, wider shoulders, and new guardrails.

After a season of preparatory work in 2024, including locating utilities and planning for overhead sign placement, the focus now shifts to finishing these vital upgrades at the so-called Spaghetti Junction according to CDOT. Drivers are advised to remain vigilant during the daytime work hours that run from Monday to Friday, 7 a.m. to 5 p.m., navigating through the inevitable single and alternating lane closures, traffic cones, and the frequent ingress and egress of construction vehicles.

Heightened caution is urged for those passing through the work zone, where speed limits are posted and enforced to secure the safety of both the public and the workers on site. In light of the ongoing construction, pertinent travel information including road conditions and travel alerts can be obtained from the project's webpage, the COtrip Planner app, or by connecting with @ColoradoDOT on various social media platforms.
