NYC (KXAN) - Amazing time-lapse video shows the progress made on the massive One World Trade Center, also known as 1 WTC and the Freedom Tower.
It is the main building of the new World Trade Center complex in Lower Manhattan in New York City and will be a 104-story skyscraper. It sits where the original 6 World Trade Center once stood -- in the northwest corner of the 16-acre World Trade Center site.
Construction crews began work more than six years ago, and it was given its official name -- One World Trade Center -- in 2009.
The tower will be the third-tallest building in the world -- the tallest in the Western Hemisphere -- once complete in 2013.
