A steel beam that was signed by President Barack Obama in June has been lifted into place on the 104th floor at One World Trade Center.
A crane atop the building raised the beam from the ground after dozens of people, including construction workers and police officers, added their own signatures near those of the president and first lady Michelle Obama.
"It feels really good to be a part of it," said iron worker James Brady, part of the crew that lifted the beam. "I feel very proud to be here. I feel very lucky to be here."
On June 14, the Obamas visited the skyscraper that's being built to replace the twin towers destroyed by terrorists on Sept. 11, 2001. The white beam contains the words "One World Trade Center" painted in blue. Obama wrote in marker: "We remember," "We rebuild" and "We come back stronger!"
Aside from the Obamas, Governor Andrew Cuomo, Governor Chris Christie and others signed the beam. The signatures will no longer be visible as the beam, which is 35 feet long and weighs 11,000 pounds, is enveloped by the structure.
"It will be, as the rest of the beams are, one that will support this building in years to come, decades to come," said Steven Plate, head of World Trade Center construction for the Port Authority of New York and New Jersey, which owns the site.
The skyscraper, formerly known as the Freedom Tower, is expected to be completed in early 2014.
