Spans - Brooklyn-Staten Island, The Narrows, New York Harbor.
According to the MTA, the Verrazano-Narrows Bridge was the world's longest suspension span when it opened in 1964.
"Its monumental 693 foot high towers 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. Each tower weighs 27,000 tons and is held together with three million rivets and one million bolts. Seasonal contractions and expansions of the steel cables cause the double-decked roadway to be 12 feet lower in the summer than in the winter." (MTA website)

The bridge was designed by Othmar Ammann, who had also designed many of the most beautiful and iconic bridges in New York City, including the George Washington Bridge, the Bayonne Bridge, the Bronx Whitestone Bridge, the Triborough Bridge, Throgs Neck Bridge and the lovely, Hell Gate Bridge (AKA, The New York Connecting Railroad Bridge).
The dramatic silhouette of the span may be best known as the starting point for the annual NYC Marathon, but it is also featured in many films set in NYC. My personal favorite is from Saturday Night Fever when Tony Manero (John Travolta) and his Bay Ridge friends all get wasted and climb all over the cables.

Crossing the span during the 2007, NYC 5Boro Bicycle Tour, one of the few opportunities for non-motorists to cross the bridge which has no provisions for pedestrians or bicyclists.
