The Brooklyn–Battery Tunnel consists of two 2-lane tubes, one in each direction. They pass underneath the East River, connecting the Battery at the southern tip of Manhattan to the neighborhood of Red Hook in Brooklyn. Although the tubes do not pass directly under Governors Island, that island contains a ventilation building for the tunnel. Vehicles over and wider than are prohibited from using the tubes. The tubes stretch from portal to portal, making them the longest continuous underwater vehicular tunnels in North America. At the time of its opening, the Brooklyn–Battery Tunnel was the longest underwater vehicular tunnel in the United States and the second-longest in the world, behind the Queensway Tunnel under the River Mersey in England.
