One World Trade Center reaches the 20th floor equivalent
One World Trade Center has reached the 20th floor equivalent level, bringing the tower to 200 feet above street level, Port Authority announced on Wednesday.
The last time Obama visited Ground Zero was as a presidential candidate on Sept. 11, 2008, when 1 World Trade Center -- then commonly known as the Freedom Tower -- was below street level, the memorial plaza had yet to be built, and the entire project was mired in delays and cost overruns.
