LIRR Third Track Update - December 2021

During the month of December, you will see crews performing construction activities in Garden City.

3rd Track Installation

Crews from J-Track will be installing the 3rd Rail over the Denton Avenue bridge. As a result, Denton Avenue is scheduled to be closed overnight from December 7 to 8 from approximately 9 pm to 6 am.

Wall Construction

On the north side of the tracks, from Nassau Boulevard to approximately Cornelia Avenue, crews will install support of excavation (SOE) to allow upcoming wall construction.

Merillon Avenue Station Enhancement

  • 3TC is working hard on completing punch list items throughout the station, including platform shelters, brick façade on columns, and other amenities.
  • Work on the north support building will continue.
  • EJ Electric is continuing to install signage bands, conduit, and light fixtures along the platforms on the north and south sides of the tracks.

Tanners Pond Road / Denton Avenue Bridge Replacement Project

  • Crews will begin early utility relocation work to accommodate for the upcoming bridge replacement. This work may require traffic alterations.
    • As a result, local road closures and detours may be necessary.
    • It is expected that Tanners Pond Road/Denton Avenue will close from Main Avenue to Railroad Avenue while 3TC completes this project element.
    • Thru traffic will be redirected to alternate routes. Work zone traffic control (WZTC) signage will be posted throughout the closure.
  • The Tanners Pond/Denton Avenue Bridge is the last of seven bridges to be replaced or modified as part of the project.
    • The bridge is scheduled to be removed and replaced with a three-track structure to accommodate the new third track and improve safety while maintaining the bridge's character.
    • An ADA-compliant sidewalk is planned on the east side of the roadway which will allow pedestrians to traverse safely between the north and south sides of the tracks.

LIRR Work Along The Right-of-Way

  • In addition to 3TC's activities, you may see or hear LIRR forces working along the railroad right-of-way.
  • To avoid LIRR service interruptions during peak commuting hours, LIRR work along the railroad right-of-way may take place overnight and on weekends.
