Description: The $2 billion WTC Transportation hub will sit at the northeast corner of the WTC site at Church and Vesey Streets and is expected to form an underground connection between the World Financial Center and the Metropolitan Transportation Authority's Fulton Street Transit Center. Through it, pedestrians will have access to Hudson River ferry terminals, PATH trains, 14 subway lines, and, potentially, a direct rail link to JFK International Airport.

Calatrava originally unveiled his design to the public in early 2004 and revised it in late July 2005 to address security, engineering, and feasibility elements for the landmark structure.
