Cranberry Tube Shuts Down for 10 Weekends of Sandy Repairs

Rockaway Line, May 6, 2013.

The Cranberry Tube, which carries the A Subway and C Subway Lines between Lower Manhattan and downtown Brooklyn, will be shut down in both directions for 10 non-consecutive weekends of Superstorm Sandy-related repairs in 2015. The MTA estimates a total of 40 weekends of intensive work is required for the repairs, with full weekend shutdowns scheduled to take place between summer 2015 and summer 2016.

The work in the Cranberry Tube is necessary to fix the severe damage caused by the storm surge that flooded the tunnel during Superstorm Sandy. More than 1.5 billion gallons of salt water infiltrated the length of the tunnel, which runs nearly 5,800 feet long. The water damaged tracks, signals, pumping equipment, electrical equipment and switches. In the immediate aftermath of Sandy, temporary repairs allowed a fast and safe return to service, but a thorough examination of the tunnel’s components determined that it required permanent repair, plus upgrades and fortification of the 82-year-old tunnel against future severe weather.

The tunnel under the East River carries approximately 225,000 A Subway and C Subway customers on an average weekday. The weekend service changes for the repairs mean that trains will skip High St in Brooklyn, and Fulton St, Chambers St, Canal St and Spring St in Manhattan, in both directions. A Subway and C Subway trains will run over the F Subway Line in both directions between Jay St-MetroTech A SubwayC SubwayF SubwayR Subway and W 4 St A SubwayD SubwayC SubwayE SubwayF Subway, arriving and departing on the upper level A SubwayC SubwayE Subway platform at W 4 St. E Subway trains will continue to stop at Canal St in both directions, and at Spring St in at least one direction. 

Work started over the course of three weekends in July on Manhattan-bound tracks. Repairs to the entire tunnel are expected to take a total of 40 weekends to complete. Approximately 180,000 customers use the affected stations on an average Saturday. 

The schedule of the 2015 weekend closures is:

  • Aug 7 - 10
  • Aug 14 - 17
  • Aug 21 - 24
  • Aug 28 - 31
  • Sep 11 - 14
  • Sep 25 - 28
  • Oct 9 - 12
  • Oct 16 - 19
  • Oct 30 - Nov 2
  • Nov 13 - 16


Components that will be fixed, installed or rebuilt include power and communications cables; ducts and duct banks; pump rooms and related equipment; fan plants; substation; circuit breaker house, and signals. The repairs will be made incrementally during the weekend closures, with projects completed in time for the resumption of early weekday service.

The work in the Cranberry Tube is the fourth major Sandy-related tunnel repair project undertaken by the MTA so far. Repairs were completed in 2014 on the Montague Tube, which carries the R Subway Line, and the Greenpoint Tube, which carries the G Subway Line; work is ongoing on the Steinway Tube, which carries the 7 Subway Line.

Service to the A Subway Line was previously interrupted for Sandy-related infrastructure repairs on Broad Channel, where 3.5 miles of the line south of Howard Beach to the Rockaways had to be rebuilt from the ballast up and storm resiliency measures were installed to protect against future storm surges.
