Public Works Announces Niwot Road Median Closure Near Diagonal Highway — Superior Area

Boulder County Public Works announces a temporary median closure on Niwot Road near the CO-119 Diagonal Highway intersection for utility infrastructure improvements. The closure will affect left turns from Niwot Road onto the Diagonal Highway for approximately six weeks. A signed detour route will be in place.

Environmental review of the project area near Baseline Road found 9 sensitive species and 2 wetland areas requiring mitigation. The Sheriff’s Office worked with Colorado Parks and Wildlife to develop a habitat conservation plan.

Colorado state law requires all counties to provide these services to eligible residents. Boulder County exceeds minimum state requirements by offering expanded hours, multilingual support, and online access. In 2024, the county received a state award for excellence in service delivery.

Community Impact

The Walker Ranch open space property encompasses 354 acres and features 4 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

Volunteers contributed over 12,208 hours to this program last year. The Sheriff’s Office coordinates with 20 nonprofit partner organizations throughout Boulder County to deliver services.

The Longmont Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 4,949 seniors participated in center programs last year.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 36% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
