Erie Community Briefing: 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.

Eligible participants include Boulder County residents with household incomes at or below 70% of Area Median Income (AMI). For a family of four, this is approximately $114,000 per year. Applications are processed on a first-come, first-served basis.

The project includes improvements along Baseline Road between Nederland and the intersection with SH-7 / Ute Highway. Construction is scheduled to begin in September 2026 with completion expected within 15 months.

Eligibility

Residents in the Nederland area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Resource Conservation at (303) 441-8454 to verify eligibility and requirements.

Funding of $14,000 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.
