The 1.6 mile tunnel that carries the A and C trains between Manhattan and Brooklyn under the East River will be shut down in both directions this weekend. This will mark the first of 40 non-consecutive weekends of repairs to fix integral components heavily damaged by Superstorm Sandy, the MTA wrote in a press release.

These repairs are all part of the larger $96.7 million Cranberry Tube project that will also include installations and fortifications to the power and communications cables, ducts and duct banks, pump rooms and related equipment, fan plants, a substation, a circuit breaker and signals.

A and C trains will use the F Line between Brooklyn and Manhattan during these closures and riders can also use nearby alternatives for all five stations closed during the work.

There will be 10 non-consecutive weekends of full tunnel closures in 2015 and the rest of the repairs will take place during weekend closures through the summer of 2016.

“The Cranberry Tube project is the next phase in what is the most extensive reconstruction and fortification effort in the history of the New York City subway system.” said NYC Transit President Carmen Bianco, in a press release. “This effort is well underway and we continue to face the challenge of performing these vital tasks as quickly and effectively as possible while minimizing the impact on our customers’ commutes.”
