Update: Public Works Announces Niwot Road Median Closure Near Diagonal Highway (2024)

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.

Eligible participants include Boulder County residents with household incomes at or below 60% of Area Median Income (AMI). For a family of four, this is approximately $111,000 per year. Applications are processed on a first-come, first-served basis.

The project includes improvements along South Boulder Road between Gunbarrel and the intersection with Left Hand Canyon Drive. Construction is scheduled to begin in June 2026 with completion expected within 6 months.
