One World Trade Center (WTC 1) in New York City, under construction. I make updates when the tower rises (about twice a month or when the tower is rising).UPDATE: This is how the tower looks on 08/05/2010. Topped out of tower is expected by the end of 2011 and open in 2013. Skyscraper will be 541 meters tall (with spire, 417 to the roof) and it will be the tallest skyscraper in USA. WTC 1 is a part of new World Trade Center.
