The final pieces of the 408-ft steel spire for One World Trade Center were lifted to the top of the tower and installed last month. Using a crane located high above street level, ironworkers lifted the final two pieces off of a temporary work platform on the roof of One WTC and attached them to the previously installed 16 sections of spire. During the installation, ironworkers set and tightened 60 bolts at an altitude of 1,700 ft. Photo: The Port Authority of New York & New Jersey
One World Trade Center is now the tallest building in the Western Hemisphere and the third-tallest in the world, standing at a symbolic 1,776 ft high.
Eighteen barrel-shaped sections of steel make up the tower’s spire, which weighs nearly 760 tons and will function as a world-class broadcast antenna.
The Port Authority of New York and New Jersey has released additional photos and video from last month’s installation of the final spire pieces atop One WTC.
You can also view a spectacular photo on CBS News’ website showing WTC ironworkers placing the spire on top of the skyscraper.
One WTC is set to open in 2014. More information on its construction progress can be found at www.panynj.gov/wtcprogress.
