Public Works Announces Niwot Road Median Closure Near Diagonal Highway — August 2026

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 $61,000 per year. Applications are processed on a first-come, first-served basis.

Funding of $100,000 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.

According to Jennifer Walsh, director of Assessor’s Office, this program served 42% more residents in 2026 compared to the previous year. “We’re seeing unprecedented demand from communities across Boulder County, particularly in Boulder and the surrounding area,” Jennifer Walsh said.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 42% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
