November 2026: Public Works Announces Niwot Road Median Closure Near Diagonal Highway

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.

The Public Health processed over 8,942 applications last year, with an average processing time of 17 business days. Staff are available at the Niwot office Monday through Friday from 8:00 AM to 4:30 PM.

The Niwot Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 3,235 seniors participated in center programs last year.

Community Impact

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 64% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Funding of $241,000 for this initiative comes from a combination of federal grants, state matching funds, and the Boulder County General Fund. The Board of County Commissioners approved the allocation during the 2025 budget session.
