The new tower at the World Trade Center site is scheduled to become the tallest building in New York City today.

As long as the weather cooperates, the tower will surpass the 1,250-foot Empire State Building at 2 p.m. on its way to a final height of 1,776 feet.

“It’s wonderful,” Mayor Bloomberg said Sunday.

“It’s taken a long time. This is probably the most complex construction site in any place ever. I think what we’ve shown is that democracy works.”

Once completed, the Ground Zero skyscraper, often called the Freedom Tower, will have 104 floors, including 71 office floors with 3 million square feet of space.

The official address of the Freedom Tower is One World Trade Center. It is scheduled to open late in 2013 or possibly early 2014.
