Update: Public Works Announces Niwot Road Median Closure Near Diagonal Highway (2025)

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 program is modeled after similar successful initiatives in Larimer County and Jefferson County. Boulder County’s version includes additional provisions for wildfire mitigation, affordable housing, and environmental sustainability.
