A crane on top of the building lifted the beam from the ground Thursday after dozens of people, including construction workers and police officers, added their own signatures.

Back in April, One World Trade Center surpassed the Empire State Building as the tallest building in New York City.

Then on June 25, a topping off ceremony was held for 4 World Trade Center as the final steel beam for that tower was lifted into place.

More than 100 construction workers signed the beam before it was hoisted 977 feet by a crane and placed on top of the building.

The beam signed by Obama for One World Trade Center is 35 feet long and weighs 11,000 pounds.

The skyscraper is expected to be completed in early 2014.
