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.

Funding of $170,000 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.

Safety data from the Gunbarrel area shows 42 reported incidents in the past 12 months, a 23% change from the previous year. The Sheriff’s Office has increased patrols along 63rd Street and added community outreach programs in response to resident feedback.
