Public Works Announces Niwot Road Median Closure Near Diagonal Highway Near Pine Brook Hills

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.

Public comment on this matter can be submitted through the Boulder County online portal, by email to Assessor’s Office, or in person at the next Board of County Commissioners meeting. Written comments received by 5:00 PM the day before the hearing will be included in the public record.

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 71% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Volunteers contributed over 2,864 hours to this program last year. The Assessor’s Office coordinates with 18 nonprofit partner organizations throughout Boulder County to deliver services.

Transportation access remains a key concern. Boulder County’s Via mobility program provides door-to-door transit service for residents in Louisville and surrounding communities who cannot access fixed-route bus service. RTD routes B, J, and BOLT serve major corridors.
