Personal Project; The Art Of New York’s Bridges Page 2
At this stage of my project I believe I will have all the images I need for
my book in about 4-5 years, but that's just guessing. Like any artist
working on any major project, I feel I have to fulfill my vision--without
doing that I will not feel a sense of completion about this work.

Some Quick Facts About The George Washington Bridge
An absolute engineering marvel, the George Washington Bridge was designed by the great Swiss engineer Othmar Ammann, whose findings during that project made possible all other large-scale suspension bridges, including the Golden Gate Bridge in San Francisco. Ammann went on to design many other bridges in the New York City area, including the mighty Verrazano-Narrows Bridge, the longest suspension bridge in the world when it opened to traffic in 1964. And the Bayonne Bridge, another of Ammann's masterpieces, was the longest above arch bridge when it opened in '31, modeled as it was after the Hell Gate Bridge in New York. The Sydney Harbour Bridge in Australia also took its design from the Hell Gate, but the Bayonne Bridge is 25" longer than the Sydney span.
