Railroad Quiet Zones: Project Group 1 - City of Longmont

Railroad Quiet Zones: Project Group 1

Orange Train crossing 9th Avenue in Longmont with a white SUV and Blue car waiting.

Project Group 1 for the railroad Quiet Zones project includes the four crossings listed below with the improvements. Construction started in May 2025 and was completed in July 2026. It included installation of asphalt pavement, concrete curb/gutter/sidewalk, raised medians, pavement markings, signage, fencing and installation of railroad gates with flashers.

 

A request will be filed with the Federal Railroad Administration to implement the Quiet Zone in summer 2027. If approved, the Quiet Zone will go into effect. See the project FAQs for more information about Quiet Zones and when train horns will stop sounding routinely at designated crossings.
