The Triborough Bridge, known officially as the Robert F. Kennedy Bridge since 2008, and sometimes referred to as the RFK Triborough Bridge, is a complex of three separate bridges in New York City, United States, carrying Interstate 278 and New York State Route 900G. Spanning the Harlem River, the Bronx Kill, and the Hell Gate (a strait of the East River), the bridges connect the boroughs of Manhattan, Queens, and the Bronx via Randalls and Wards Islands, which are joined by landfill.
