November 6, 202 – Construction at the northwest corners of Atwood Street and 4th and 6th Avenues is expected begin Thursday, Nov. 12, as part of the City of Longmont’s Quiet Zones project. Work is anticipated to take approximately one week and will require temporary traffic changes on southbound Atwood Street between 4th and 5th Avenues and 6th and Longs Peak Avenues. The block between 5th and 6th Avenues will remain open.

 

Crews are expected to work from 7 am to 5 pm daily, including the weekend of Nov. 14–15, if needed. Traffic restrictions will remain in place 24 hours a day during construction. The schedule is subject to change based on weather and coordination with BNSF Railway.
