New York’s Verrazano Narrows Bridge stretches 6,690 feet from Brooklyn to Staten Island in this photo taken looking towards Staten Island from the air Wednesday, June 23, 1999. The bridge is the longest suspension bridge in North America, with 693-foot-high towers that are 1 5/8 inches farther apart at their tops than at their bases because the 4,260 foot distance between them made it necessary to compensate for the earth’s curvature.
