Cost of World Trade Center Transit Hub 2x as Much as Predicted
NEW YORK, NY - JANUARY 06: A construction worker looks over Ground Zero and the lower Manhattan skyline from the eastern face of 1 World Trade Center January 6, 2011 in New York City. The tower has reached 52 floors, roughly halfway to its final height. Workers are adding nearly a floor a week to the building which will be the tallest in New York when it is completed in 2013.

Planners of the new World Trade Center say they need another $180 million to finish a major transit hub at the site.
An official at the Port Authority of New York and New Jersey told the agency's commissioners Thursday that the price of the train and subway station has climbed to $3.44 billion.
Construction director Steven Plate says soaring steel arches designed for the building by architect Santiago Calatrava will cost $221 million, about twice as much as estimated.
Plate says designers had to add extra steel to protect against terrorist attacks. Shipping costs also rose after planners decided to use a foreign contractor that had experience with Calatrava's designs.
Plate says the Port Authority will have to dip into a contingency fund to complete the building.
