May: 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.

Environmental review of the project area near SH-7 / Ute Highway found 11 sensitive species and 4 wetland areas requiring mitigation. The Housing & Human Services worked with Colorado Parks and Wildlife to develop a habitat conservation plan.

Funding of $81,000 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 2026 budget session.
