One World Trade Center is now taller than the Empire State Building to become New York City's highest skyscraper even though it won't be completed until next year. Construction began in 2006 on the site of the original World Trade Center Twin Towers that were destroyed in the 9/11 terrorist attacks.

When it is completed in 2013, One World Trade Center will stand at 1,776 feet compared to the Empire State which towers at 1,250 feet. It will become the tallest building in the United States and the third tallest in the world.

EarthCam, an international webcam technology company, has a released a video of the construction site since 2006. The film has put together a video from time-lapsed photography using images taken every 15 minutes.
