Brooklyn–Battery Tunnel
Appearance
The Brooklyn-Battery Tunnel in New York City crosses under the East River at its mouth and connects the Boroughs of Brooklyn and Manhattan, passing under but providing no access to Governor's Island. Opened to traffic in 1950, it consists of twin tubes, carrying an aggregate of four traffic lanes.
The battery refered to in the tunnel's name refers to Castle Clinton, the former fortification at the southern tip of Manhattan Island.
The tunnel is owned by the City of New York and operated by the Triborough Bridge and Tunnel Authority, an affiliate agency of the Metropolitan Transportation Authority (New York).
