By 2020, New York City will be home to the tallest observation deck in the Western Hemisphere and the fifth highest in the world. Called the “Edge,” the Hudson Yards observation deck will stretch over the city’s skyline from the building’s 100th floor, at a height of over 1,100 feet in the air. The viewing area will span 7,500 square feet, allowing brave visitors to walk on the glass floor in the center of the triangular structure and see clearly down to the ground below.

Built as a cantilever bridge, the “Edge” juts out sixty-five feet into the sky to offer dramatic views. Designers gave the observation deck a modern, unobtrusive style that adds to the feeling of being in the clouds. An international endeavor, designers used materials from many different parts of the world, including granite quarried in Virginia and finished in Quebec, structural glass from Germany, and steel from Italy, where the observation deck was fully assembled and then broken down into fifteen sections to be shipped by boat to New York City and reassembled.

Due to the immense weight of the observation deck, totaling around 765,000 pounds, two cranes will be required to lift each of the fifteen pieces in to place, in what Hudson Yards calls a “Jigsaw Puzzle in the Sky.” Each section varies in weight, ranging from 35,000 pounds and 102,000 pounds. Each piece will be bolted together and anchored to the east and south facing sides of the skyscraper. A nine-foot-tall angled glass wall will enclose the deck. Once completed, visitors will enjoy a stunning view of New York City from an observation deck that allows them to stand right on the “Edge.”
