Boulder County

—Sugarloaf Road: Boulder County is working on the last 2013 flood recovery-related project on Sugarloaf Road. The project involves the construction of five retaining walls, drainage improvements and reconstruction of approximately 2,000 feet of roadway just up from Colo. 119 and will include a 4-foot shoulder in the uphill lane. Due to an unsafe and confined work zone, Sugarloaf will be closed between Colo. 119 and Betasso Road from 9:30 a.m. to noon and 1 to 3:30 p.m. weekdays. Sugarloaf will remain open in a single-lane configuration through the work zone during all other hours.

The installation of the new traffic signal may occur in the spring of 2023.

—Horizon Avenue: New stop signs have been placed at the intersections of Horizon Avenue and Colliers Parkway as well as Flora View Drive and Horizon Avenue. These signs are temporary and will be removed after work on Weld County Road 5 and associated sidewalks is complete.
