The new transit hub at the World Trade Center site is opening to the public this month. The design for the station was first revealed in 2004. It was projected to take five years and only $2.2 billion to complete, but after 12 years and many complications, $2.2 billion turned into $4 billion, making the Transportation Hub the most expensive train station ever. Though the main part of the station that connects to the PATH trains — known as the Oculus — will now be open, other parts, such as the retail space, are still under construction.
The hub was designed by architect Santiago Calatrava, who has worked on buildings in Spain, Switzerland, and Canada. He is currently designing St. Nicholas Church in Liberty Park, another building that was destroyed during the 9/11 attacks.
