Construction Starting June 16 at the 9th Avenue Railroad Crossing

Construction is planned to start Monday, June 16 at the 9th Avenue railroad crossing between Collyer Street and Baker Street for the City of Longmont Railroad Quiet Zones Project. One lane of traffic on 9th Avenue will be closed in both directions across the railroad crossing for approximately four weeks. Additional intermittent lane closures may be required until construction at the crossing is complete at the end of August.

This is part of the first group of crossings to receive safety improvements that will eventually be designated as a Quiet Zone through downtown Longmont. The other crossings in this group include 17th Avenue, Longs Peak Avenue/Atwood Street and 3rd Avenue/Atwood Street.

A Quiet Zone is a section of railroad where trains do not routinely sound their horns at road crossings. However, multiple adjacent crossings will need to have safety improvements before a full Quiet Zone can be designated. Therefore, you may continue to hear train horns after construction is completed at these crossings until other adjacent crossings are also completed. For more information, visit the Quiet Zones in Longmont webpage.

Regular construction hours are Monday – Friday from 7 am – 5 pm. Some work may occur until 7 pm and also on Saturdays and Sundays, as necessary. Detour signs will direct vehicle and pedestrian traffic to alternate routes, as needed. In some cases, a full closure of the railroad crossing is required. Check the project webpage for the latest information.
