The Verrazano-Narrows Bridge, between Staten Island and Brooklyn, New York, is the longest single suspension bridge in the world. It is named for Giovanni da Verrazano, Florentine explorer who discovered New York harbor in about 1524. The massive span features a double deck thoroughfare, each wide enough for six lanes of traffic. The diameter of the cables measures 1 yard-identical with those on the George Washington Bridge. The Narrows Bridge is important in that it by-passes New York City. A map, illustrated on the stamp itself, pinpoints the positions of the Bridge with its close relationship to Staten Island and Brooklyn and also Manhattan and Jersey City, New Jersey.
