Interstate 678 (I-678) is a north–south auxiliary Interstate Highway that extends for through two boroughs of New York City. The route begins at John F. Kennedy International Airport on Jamaica Bay and travels north through Queens and across the East River to the Bruckner Interchange in the Bronx, where I-678 ends and the Hutchinson River Parkway begins. I-678 connects to I-495 (the Long Island Expressway) in Flushing Meadows–Corona Park. The highway is known as the Van Wyck Expressway ( or ) from JFK Airport to Northern Boulevard (New York State Route 25A or NY 25A), the Whitestone Expressway from NY 25A north to the Bronx–Whitestone Bridge, and the Hutchinson River Expressway from the bridge to the Bruckner Interchange. North of the interchange, I-678 ends and the roadway continues as the Hutchinson River Parkway. The portion of I-678 north of NY 25A follows the path of the Whitestone Parkway and a short section of the Hutchinson River Parkway's Bronx extension. The Whitestone and Hutchinson River parkways were first opened in 1939, while the Van Wyck Expressway opened in pieces between 1950 and 1953. Both highways were connected to each other and upgraded to meet Interstate Highway standards in the early 1960s. The Hutchinson River and Whitestone Expressways were collectively designated as I-678 . The designation was extended southward in 1970 to follow the Van Wyck Expressway to its end at JFK Airport. Route description I-678 begins at JFK Airport in the borough of Queens and proceeds along the stretch of highway known as the Van Wyck Expressway. I-678 progresses westward through the airport, crossing under airport taxiways as a six-lane freeway. Just after the taxiways, the expressway connects with North Service Road, which services the airport's western services. From there, the expressway begins to turn northward and crosses the United Airlines hangar. I-678 continues its northwestern path, curving to the northeast at the interchange with Federal Circle. From there, the highway continues northward, becoming a divided highway and meeting NY 878 (the Nassau Expressway) at exit 1E. I-678 continues northward, crossing under the Nassau Expressway and over NY 27 east (South Conduit Avenue) and the Belt Parkway. A short distance later, the highway intersects NY 27 west (North Conduit Avenue) at exit 1B. At this point the highway exits the facility of JFK Airport and maintenance switches to the New York State Department of Transportation. North of North Conduit Avenue, AirTrain
