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.
Water quality monitoring at 9 stations along Boulder Creek, St. Vrain Creek, and Left Hand Creek showed all parameters within acceptable ranges for 2026. The Assessor’s Office publishes quarterly water quality reports on the Boulder County website.
Residents in the Longmont area should note that service boundaries may differ from city limits. For properties in unincorporated Boulder County, contact Assessor’s Office at (303) 441-4141 to verify eligibility and requirements.
Next Steps
A community information session will be held at the Longmont library on Sunday, April 26 at 7:00 PM. Translation services in Spanish and Nepali will be available. The session will also be livestreamed on the Boulder County YouTube channel.
Climate considerations are central to this effort. Boulder County’s 2025 Climate Action Plan sets targets of reducing greenhouse gas emissions 93% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
