G Greenpoint Tube Set to Close Next Friday Night for Five Weeks of Fix&Fortify Sandy-Related Repairs

Published on : Saturday, July 19, 2014

MTA-Rail (1)Fix&Fortify Sandy Recovery Work is returning to the G Subway Line Icon Greenpoint Tube for five consecutive weeks starting next week.  The next phase of this important work will begin at 10:30 p.m. Friday, July 25 with service scheduled to resume at 5:00 a.m. Tuesday, September 2.   During that time, G Subway Line Icon train service will be suspended between Long Island City-Court Sq and Nassau Av.

 

The tube, which connects Long Island City with the Greenpoint section of Brooklyn, suffered extensive damage during Superstorm Sandy when 3 million gallons of salt water flooded the tunnel at the height of the storm.

 

 

Tracks and equipment were totally submerged, and the tunnel’s pump controls, electrical, communications, fan control and signal equipment all incurred serious damage.  Power cables immersed in salt water corroded from the inside, while corrosion on rails and fasteners increased the potential for delay-causing failures.

 

 

The controls for ventilation, lighting and communication systems were all destroyed and have yet to be restored to their level of pre-Sandy reliability. While the MTA worked tirelessly to restore service as quickly as possible after the storm, it was immediately clear that future, more extensive work would be necessary to repair and rebuild these vital systems in order to ensure safe and reliable service.
 

“Our goal is to complete this work as quickly and efficiently as possible while exposing our customers to as little inconvenience as we possibly can by using the more lightly-traveled summer weeks to make repairs,” said NYC Transit President Carmen Bianco.  “To that end, we are providing an extraordinary amount of information to help our customers navigate around this vital work.”

This closure will allow crews to go in and work intensely on the damage caused by Sandy.  This work is not suited to weekend closures and requires full 24/7 access to get the work completed effectively.  During this upcoming, five-week closure, the northernmost three stops on the G Subway Line Icon line, Greenpoint Av, 21 St and Long Island City-Court Sq will be closed.  During this closure, G Subway Line Icon trains will still operate to and from Church Av and Nassau Av.  Free shuttle buses will be provided during the duration of the work linking the closed stops.
 

The shuttle buses will run along two routes to provide alternate service to/from affected stations and Court Sq [7]E Subway Line IconM Subway Line Icon:

 
1. Via Manhattan Av to/from Nassau Av G Subway Line Icon station
2. Via McGuinness Blvd to/from Lorimer St/Metropolitan Av L Subway Line Icon station

Shuttle bus stops along each route will be located near [G stations at:

Southbound
Jackson Av and 45 Av
Jackson Av and 47 Av
Manhattan Av/McGuinness Blvd and Greenpoint Av
Manhattan Av/McGuinness Blvd and Nassau Av
Metropolitan Av and Union Av

Northbound
Metropolitan Av and Union Av
Manhattan Av/McGuinness Blvd and Nassau Av
Manhattan Av/McGuinness Blvd and Greenpoint Av
44 Drive and 23 St
A map of the shuttle bus routes is available online at http://web.mta.info/nyct/service/G_GreenpointTubes_FixFortifyMap.pdf.

Connections to Manhattan service will be available at:
L at Lorimer St/Metropolitan Av.
JM via free out-of-system transfer with MetroCard between the Broadway G and Lorimer St JM stations.

 
AC at Hoyt-Schermerhorn Sts.
​Previous Fix&Fortify work at the tubes was performed during weekend closures in 2013 and included the installation of cable, alarms, emergency communications systems, repair of track, conduit, structural repairs, repairs to tunnel leaks and the removal of old tunnel lighting as well as repairs to the Greenpoint and 21 St stations.

 

This time, workers will take advantage of the 24/7 access to install permanent tunnel lighting and support components, perform work in tunnel lighting rooms, install new signals, install fiber-optic cable, (including cable for vent plant, pump room, substation, and communication rooms), and install antenna cables as well as test all of the newly installed equipment.  Track Capital Construction will take advantage of the extended shutdown to complete all necessary track work.  Additionally, several elements of work requiring access to the tracks for the ventilation system will be performed.

 

The project is designed to restore and rebuild damaged infrastructure while reducing the system’s vulnerability in the event of future severe weather.  Overall, the MTA has been allocated nearly $3.8 billion in funding from the Federal Transit Administration (FTA) for repair, resiliency, and disaster relief work.
 

Customers affected by the upcoming work will have access to informational brochures.  A robust customer information campaign on the project includes posters on trains and throughout affected stations.  Print ads will appear in at least nine local publications to inform customers.  The brochures and a web- and poster-based effort will keep customers informed of the type and amount of work that has been completed.
