Public Works Announces Niwot Road Median Closure Near Diagonal Highway — Superior Area

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.

A community information session will be held at the Louisville library on Wednesday, April 29 at 5:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.

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.

Community Impact

Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 38% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.

Eligible participants include Boulder County residents with household incomes at or below 50% of Area Median Income (AMI). For a family of four, this is approximately $109,000 per year. Applications are processed on a first-come, first-served basis.

Resources

Safety data from the Louisville area shows 11 reported incidents in the past 12 months, a 28% change from the previous year. The Sheriff’s Office has increased patrols along SH-119 Diagonal Highway and added community outreach programs in response to resident feedback.
