Interstate 278 (I-278) is an auxiliary Interstate Highway in New Jersey and New York in the United States. The road runs from U.S. Route 1/9 (US 1/9) in Linden, New Jersey to the Bruckner Interchange in the New York City borough of the Bronx. The majority of I-278 is in New York City, where it serves as a partial beltway and is the only Interstate to pass through all five of the city's boroughs. I-278 follows several freeways, including the Union Freeway in Union County, New Jersey, the Staten Island Expressway (SIE) across Staten Island, the Gowanus Expressway in southern Brooklyn, the Brooklyn-Queens Expressway (BQE) across northern Brooklyn and Queens, a small part of the Grand Central Parkway in Queens, and a part of the Bruckner Expressway in the Bronx. I-278 also crosses multiple bridges, including the Goethals Bridge, the Verrazano Narrows Bridge, the Kosciuszko Bridge and the Triborough Bridge.
