NEW YORK (AP) — The new World Trade Center has reached a milestone. The skyscraper being built to replace the terror-wrecked twin towers is now 100 stories high.

That's just four feet short of One World Trade Center becoming the tallest building in New York City and surpassing the Empire State Building.

There's a special twist when it comes to counting floors in what will be a 104-story building when it opens next year.

According to the Port Authority of New York and New Jersey, the tower grew from 93 stories last week to 100. That's because six floors don't actually exist. The numbers were skipped to make up for the building's massive base, plus mechanical equipment taking up space.

Conde Nast has signed a tentative agreement to move into the tower.
