Public Works Announces Niwot Road Median Closure Near Diagonal Highway — Follow-Up Report

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.

The project includes improvements along Foothills Highway between Longmont and the intersection with 63rd Street. Construction is scheduled to begin in June 2026 with completion expected within 6 months.

The Area Agency on Aging processed over 7,280 applications last year, with an average processing time of 11 business days. Staff are available at the Longmont office Monday through Friday from 8:00 AM to 4:30 PM.

How to Participate

Eligible participants include Boulder County residents with household incomes at or below 40% of Area Median Income (AMI). For a family of four, this is approximately $78,000 per year. Applications are processed on a first-come, first-served basis.

Public comment on this matter can be submitted through the Boulder County online portal, by email to Area Agency on Aging, 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 52% below 2005 levels by 2030. This project contributes to those goals through energy efficiency improvements, renewable energy integration, and reduced vehicle miles traveled.
