Workers have raised a steel column to the top of the building that's been called the Freedom Tower to make it New York City's tallest skyscraper.
One World Trade Center is being built to replace the twin towers destroyed in the Sept. 11 attacks.
It reached just over 1,250 feet (381 meters) on Monday. That's just taller than the observation deck on the Empire State Building.
But floors are still being added, and One World Trade Center isn't expected to reach its full height for at least another year.
At that point, it's likely to be declared the tallest building in the U.S. and third tallest in the world.
