Tonight around 11:30 pm, the R train will stop running between Brooklyn and Manhattan for as long as 14 months. The MTA is shutting down the Montague Tube, the underwater tunnel that connects the R train from Brooklyn to Manhattan, to repair Sandy-related damage. (The cost of repairs is a massive $309 million.) WNYC posted a helpful “survival guide” yesterday and the MTA broke down the closures as well. On weekdays, the R train will run from Whitehall Street-South Ferry in Manhattan to Forest Avenue-71st Avenue in Queens, and from Court Street in Brooklyn to Bay Ridge-95th Street. The MTA implemented a ferry service from Sunset Park into Lower Manhattan and is increasing service on the X27 bus by around 25 percent. The R train will run between the boroughs on weekends, although Court Street and Jay Street will get skipped. Yikes. What are R train riders out there planning to do?
