Public Works Announces Niwot Road Median Closure Near Diagonal Highway — Sunshine Canyon 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.

The Lafayette Senior Center offers related programming including free legal consultations, tax preparation assistance, health screenings, and social activities. Over 4,794 seniors participated in center programs last year.

The Human Services processed over 982 applications last year, with an average processing time of 18 business days. Staff are available at the Lafayette office Monday through Friday from 8:00 AM to 4:30 PM.

Background

Funding of $64,000 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 2025 budget session.

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