The column going up is the Hydro-Raxtar setup that Atlantic Safway is using to get man and materials up to the top of the WTC.

The steel for the 124-metre antenna will raise the height of the overall structure to about 541 metres (1,776 feet), making it the tallest structure in the United States. Discounting the antenna, Willis Tower in Chicago remains the tallest building in the Western Hemisphere at 110 stories and 1,450 feet (442 metres).

It weighs about 750 tons and must be transported by boat because of its massive size. The tower’s owners said about 100 iron workers could have been laid off if the steel delivery was delayed beyond December because the St. Lawrence River would freeze.

The AGF Group out of Terrebonne Quebec will be supplying the steel Antenna that will crown what some call the LIBERTY TOWER.
