Triborough Bridge

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. The bridges connect the boroughs of Manhattan, Queens, and the Bronx via Randalls and Wards Islands, which are joined by landfill. The bridge complex, which carries Interstate 278 and unmarked New York State Route 900G, connects with the FDR Drive and the Harlem River Drive in Manhattan, the Bruckner Expressway and the Major Deegan Expressway in the Bronx, and the Grand Central Parkway and Astoria Boulevard in Queens.The three bridges of the Triborough Bridge complex are: the Harlem River vertical-lift bridge, the largest in the world, which connects Manhattan to Randall's Island; the Bronx Kill truss bridge, connecting Randall's Island and the Bronx; the suspension bridge over Hell Gate – a strait of the East River – which connects Ward's Island to Astoria in Queens.These are connected by an elevated highway viaduct across Randall's and Ward's Islands and 14mi of support roads. Also part of the complex is a grade-separated T-interchange on Randall's Island, which sorts out traffic in a way that ensures that drivers pay a toll at only one bank of toll booths.
