The Verrazano-Narrows Bridge, with a centerspan of 4,260 ft and side-spans of 1,215 ft, has the longest suspended span built to date (1966). With twelve traffic lanes on two decks, it also carries more load per span than any previous bridge. A relatively shallow depth of suspended structure and high aerodynamic resistance is obtained by a novel rigid framing of the entire steel structure. The suspended structure is carried by four 36-in.-diameter cables. The two towers are 693 ft high. The bridge is part of the new arterial facilities in the New York metropolitan area.
