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 08/03/2011 (285m/937ft//76fl) and cladding up to 53th floor . The tower will be topped out by the end of 2011 and open in 2013. The skyscraper will be 541 meters/1776 feet tall (with spire, 417 m / 1368 ft to the roof) and it will be the tallest skyscraper in USA. WTC 1 is a part of new World Trade Center. This is second model of rising structure, because previous model has reached maximum numbers of accepted revisions.
