Building BridgesThis image was taken from a walking bridge in Poughkeepsie, New York. This boat is moving down the Hudson with parts for the Tappan Zee replacement bridge. The first Tappan Zee bridge is a cantilever bridge that spans the Hudson River at one of its widest points. Unlike most bridges, the Tappan Zee was designed in 1950 to only last approximately 50 years because of a material shortage due to the Korean War. The new replacement bridge is being built with a 100 year life expectancy and is expected to be completed by 2018.
