After a several delays and a winter shutdown, the City Longmont is expected to begin construction at the 3rd Avenue/Atwood Street railroad crossing on March 11. Construction is anticipated to be completed in June. This is part of the first set of crossings to receive safety improvements for the Railroad Quiet Zones Safety Improvements project.

For approximately 12 weeks:

• • There will be single-lane closures on 3rd Avenue near the Atwood Street intersection. At least one lane of traffic will be open in both directions.
  • Both the northbound and southbound lanes of Atwood Street will be closed at the intersection just north of 3rd Avenue.
  • Residents on Atwood Street between 3rd Avenue and 4th Avenue will use designated detour routes.
  • All sidewalks at the intersection will be closed during construction. Pedestrians should follow signs for detour routes.

In early April, there will be a full closure of the intersection at 3rd Avenue and Atwood Street for approximately three weeks.

• • No through traffic will be allowed at the intersection.
  • Traffic will need to detour to 4th Avenue for east/west travel and Martin Street or Collyer Street for north/south travel.
  • Trucks should avoid using 3rd Avenue as a through-route and are encouraged to use CO 119 or 9th Avenue for east/west travel.
  • Local traffic will be able to access driveways along 3rd Avenue and Atwood Street from the designated detour routes.
  • All sidewalks at the intersection will be closed during this time. Pedestrians should follow signs for detour routes.

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.
