When riding through the World Trade Center site on the 1 train, you may have paused to wonder, "Hey, aren't they building a huge new transportation hub all around this subway right now?" Indeed they are, "they" being the Port Authority. So how are they keeping the train running while the PATH station gets its wings and other WTC redevelopment madness rages on? Simple: Levitation! The Port Authority built a temporary support structure to hold the concrete subway tunnel in place while the transportation hub and other new rebuilding bits get added. The Tribeca Trib has a good lengthy report explaining this feat of engineering, but we sent in Curbed photographer Will Femia to get some cool visual constructoporn.
