One World Trade Center is about to become the tallest building in the Western Hemisphere.
Crews are set Monday to raise the final two sections of the skyscraper’s 408-foot spire, bringing it to its final height of 1,776 feet, according to officials.
Construction on the stainless steel spire began in December, when pieces of it started coming into the city from New Jersey and Canada.
The structure contains 18 sections and weighs nearly 800 tons. The 104-story tower became the city’s tallest building about a year ago.
Legends Hospitality LLC, which is based in the city, was selected last month to run the tower’s observation deck, which is expected to host some 3.8 million annual visitors from 1,250 feet above the street.
It’s hoped that the deck will bring in about $875 million in annual revenue to the Port Authority over the course of its 15-year lease, officials said.
The building is set to open sometime next year.
