Construction has started on a super tall skyscraper observation deck in Manhattan's Hudson Yards, the most expensive real-estate development in US history.
Costing an estimated $20 billion, Manhattan's Hudson Yards neighborhood is already the largest real-estate development in American history.
And soon, the neighborhood will break another record. 30 Hudson Yards, a skyscraper under construction on the island's far west side, will feature the highest outdoor observation deck in New York City and the Western Hemisphere.
A construction crew began installing the 765,000-pound, steel deck on Tuesday. When complete, it will jut out from the tower 1,100 feet in the air.
Take a look below.
The skyscraper, dubbed 30 Hudson Yards, is located along the Hudson River at the southwest corner of 33rd Street in Manhattan.
Spanning around 28 acres, Hudson Yards broke ground in late 2012, and construction is expected to wrap up in 2024.
Measuring 1,296-feet-tall, the steel-and-glass skyscraper will feature offices, a restaurant, a bar, an event space, and shops. It will also connect directly to the subway's 7 line.
Tenants of the tower — designed by architect Kohn Pederson Fox Associates and developed by Related Companies and Oxford Properties Group — will include include DNB Bank, Time Warner Inc., and Wells Fargo.
