The first proposed alignment for Interstate 478 extended south from the planned Lower Manhattan Expressway (I-78) across the Manhattan Bridge to the Brooklyn-Queens Expressway (I-278). The Manhattan Bridge, a suspension bridge built between 1901 and 1909, spans the East River between Canal Street in Lower Manhattan and Flatbush Avenue in Brooklyn. The Lower Manhattan Expressway was dropped in March 1971 and I-478 redesignated along the Brooklyn Battery Tunnel and proposed Westway.2
The Brooklyn Battery Tunnel opened to traffic on May 25, 19503 as the longest continuous underway vehicular tunnel in North America. The crossing took ten years to build.4 The tunnel was renamed after Brooklyn native Hugh L. Carey, a former Congressman and Governor of New York (1975-82) on October 22, 2012.3
