The Brooklyn–Battery Tunnel, officially the Hugh L. Carey Tunnel and commonly referred to as the Battery Tunnel, is a tolled tunnel in New York City that connects Red Hook in Brooklyn with Battery Park in Manhattan. The tunnel consists of twin tubes that each carry two traffic lanes under the mouth of the East River. Although it passes just offshore of Governors Island, the tunnel does not provide vehicular access to the island. With a length of 9,117 feet (2,779 m), it is the longest continuous underwater vehicular tunnel in North America.
