The phrase "only in New York" is probably overused, but there are times when it still applies. A plan to build an entire 26-acre neighborhood with 17 million square feet of buildings atop two platforms suspended over an active rail yard serving America's busiest train station is one of those times.
The neighborhood will be known as Hudson Yards, and construction officially began today on the first of those platforms — over the eastern part of the rail yard. That platform will ultimately hold two office towers, two residential towers (one of which will have a hotel), a million square feet of retail, and about five acres of open public space. And it will all come together as 30 Long Island Railroad tracks remain in operation to serve commuters through Penn Station.
