A steel beam signed by President Obama was lifted into place today on the 104th floor at One World Trade Center. A crane on top of 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.
On June 14, the Obamas visited the skyscraper that's being built to replace the twin towers destroyed in the 9/11 attacks. 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!" 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. The skyscraper, also known as the Freedom Tower, is expected to be completed in 2014.
