Weld County Road 77 reopens after improvements
Published on October 22, 2025
A five-month effort to improve Weld County Road (WCR) 77 wrapped up Wednesday when the road north of Briggsdale reopened following improvements between WCR 106 and WCR 114.
“Weld County Road 77 is an important transportation route in the northern part of our county. It sees heavy commuter, truck, and agricultural traffic, so rebuilding it is critical to ensure it can continue transporting people and goods safely and efficiently,” said Curtis Hall, Director of the Weld County Department of Public Works. “We’ve now successfully rehabbed 12 miles of WCR 77 since 2023. We’re happy with the results, and we believe the traveling public will be as well.”
Similar to work completed on the road over the last two years, work on the four-mile segment of WCR 77 between WCR 106 and WCR 114 focused largely on strengthening the road’s structure. Crews within Weld County Public Works completed construction, which involved milling existing asphalt and profiling the road — a process of cutting dirt along the roadway and filling it in other areas to allow for better sight distance or wider shoulders. Prior to paving, crews applied aggregate base course and a cement-treated base — all elements crucial to making the road resistant to cracking from the effects of heavy traffic and freeze-thaw.
“The process used to rebuild this road, known collectively as full-depth reclamation, or FDR, is one we’ve used for several years with great results,” Hall said. “It allows us to reuse a portion of existing asphalt, which saves time and money versus using completely new material, a benefit that better utilizes taxpayer dollars.”
While the road structure and driving surface received much attention, seven culverts were repaired or replaced during the project. New signs and delineators were placed along the road, and care was taken to seed and mulch the area, while logs were strategically placed near construction to stabilize nearby soil and prevent erosion. Steps were also taken to minimize delays on the traveling public by starting the project after the Pawnee School District’s graduation ceremony in May and temporarily pausing construction during the Earl Anderson Memorial Rodeo in June.
“As we see with every road project, there are many more steps involved than what meets the eye — It’s all part of delivering the best improvements possible, from the road structure to the surface,” said Jason Maxey, Weld County Commissioner and Coordinator of public works. “We’re happy these improvements are complete and that they’ve built on recent improvements to county road 77.”
Those recent improvements include work completed on WCR 77 from Colorado Highway 14 to WCR 100 in 2023 and from WCR 100 to WCR 106 in 2024. The next phase will begin next summer with work on WCR 77 between WCR 114 and WCR 122.
