It's official — New York's new World Trade Center beat out Chicago's Willis Tower for the tallest building in the U.S.

A team of experts with the Height Committee on the Council on Tall Buildings announced Tuesday the skyscraper clocks in at 1,776 feet, surpassing Willis Tower by 326 feet. (Via NBC)

And it's all thanks to a design change that added a 408-foot needle to the top of the World Trade Center. (Via WABC)

See, the committee debated whether the addition should be considered as part of the actual building or the equivalent of a broadcast antenna, but they decided to count the needle as a spire and, therefore, a permanent part of the structure.

He told the Chicago Tribune, "I would just say to all the experts gathered in one room, if it looks like an antenna, acts like an antenna, then guess what? It is an antenna... I think (with) the Willis Tower you will have a view that's unprecedented in its beauty... Something you can't do from an antenna."
