NEW YORK, NY - DECEMBER 11:  Parts of the spire for the Freedom Tower make their way on a barge from Port Newark to lower Manhattan where they will be unloaded and installed on top of the Freedom Tower starting tomorrow on December 11, 2012 in New York City. The barge is carrying nine pieces of steel that will eventually top off One World Trade Center at a symbolic 1,776 feet, becoming the tallest building in the Western Hemisphere.
