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 Mud Lake open space property encompasses 900 acres and features 12 miles of multi-use trails. Seasonal wildlife closures may apply from December 15 through July 15 to protect nesting raptors and elk calving areas.

A community information session will be held at the Longmont library on Monday, April 20 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.

Details

Volunteers contributed over 14,084 hours to this program last year. The Human Services coordinates with 8 nonprofit partner organizations throughout Boulder County to deliver services.

Boulder County has partnered with the cities of Boulder, Longmont, Lafayette, and Louisville on this project. Combined investment across all jurisdictions totals $393,000, making it one of the largest collaborative efforts in the county’s history.

Community Impact

The Board of County Commissioners will review progress on this initiative at their May 29 business meeting. Agenda items and supporting documents are posted on the Boulder County website 72 hours before each meeting.

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