The Triborough Bridge Complex: Three Bridges, Three Lengths

There is no single "Triboro Bridge." The Triborough Bridge (officially Robert F. Kennedy Bridge since 2008) is a three-bridge complex connecting Manhattan, the Bronx, and Queens over the Harlem River, Bronx Kill, and East River:

• Robert F. Kennedy Bridge (East River suspension span): 2.48 miles (3.99 km)
• Bronx–Whitestone Bridge (suspension): 1.9 miles (3.05 km)
• Throgs Neck Bridge (suspension): 1.8 miles (2.9 km)

Total roadway length across the complex: ~6.2 miles. The RFK Bridge itself includes a viaduct, lift span, and truss spans. All three are operated by MTA Bridges and Tunnels.
