The Hugh L. Carey Tunnel is the southernmost crossing of the East River, connecting Brooklyn and Manhattan. It connects to the Brooklyn-Queens Expressway (I-278) on the Brooklyn side. On the Manhattan side, the tunnel ends at West Street (NY 9A) near Battery Park and the southern terminus of the FDR Drive. The tunnel carries the designation of I-478, although there are no signs giving the route number.
The Hugh L. Carey Tunnel was originally known as the Battery Tunnel. In 2012, it was renamed after Hugh L. Carey, who was a governor of New York State.
