Construction workers applauded as the spire was attached. The building is a symbol of the nation's resolve following the 911 attacks. According to MSN the 408-foot spire, weighing 758 tons, will serve as a world-class broadcast antenna. An LED-powered light emanating from it will be seen from miles away and a beacon will be at the top to ward off aircraft.

The building will open in 2014.
