The new design for the World Trade Center Transportation hub was scaled back from original plans due to the skyrocketing cost of steel and because the WTC Transportation Center is running way behind schedule.
Gone are the planned wide open spans and the skylights of the World Trade Center Transportation hub. Instead, tapered columns have been added. Since the hub needs to be completed by 2012, the entire design needed a second look in order to make the project manageable. Since the gold standard for transportation hubs is New York City's Grand Central Station, the World Trade Center hub has to live up to some very high expectations.
