New Nassau Boulevard Bridge in Garden City Will Be Installed October 4-6; Road Closures to be in Effect

Nassau Boulevard Bridge - 09-16-19

On-site work continues at the Nassau Boulevard Bridge in Garden City, ahead of the new bridge installation scheduled for October 4-6, 2019. The current bridge will be replaced with a structure that will support three-tracks as part of the LIRR Expansion Project. Over a single weekend, the existing bridge will be removed and the new one will be lifted and rolled into place. Following the “roll-in,” tracks, power, communications and other systems will be reinstalled in time for the morning commute on Monday, October 7. Work at the site began in June 2019.

The installation of retaining and sound walls will improve the quality of life for residents living near and around the LIRR tracks. From Denton Avenue to Nassau Boulevard, work continues for the construction of retaining and sound walls along the south side of the tracks; from Nassau Boulevard to Herricks Road crews continue to install wall sections on top of the existing retaining wall, along the north side of the tracks.

To achieve the project’s rapid timeline, partial and full road closures are essential to ensure the safety of drivers, pedestrians and workers:

  • Nassau Boulevard is currently limited to a single, southbound lane. At least one pedestrian sidewalk under the bridge is available.
  • The Main Line will be taken out of service beginning early Saturday morning, October 5.
  • To roll in the new bridge over the weekend of Oct. 4-6, Nassau Boulevard from Atlantic Ave. to Main/Merillon Ave. will be fully closed (northbound and southbound) to vehicles from Sept. 30 to Oct. 8.

This low-hanging bridge, which is currently 11’ 6”, has been the site of many accidents over the years by trucks striking it, resulting in train delays in both directions while LIRR crews worked to determine the bridge’s safety and structural stability before restoring normal train service. The new bridge, which is being assembled from sections delivered to the site at the northwest corner of Nassau Boulevard and the Main Line, will be 14’ high.
