(AP) - This 2005 file artist's rendering provided by the Port Authority of New York and New Jersey shows the planned transit hub designed by Spanish architect Santiago Calatrava for the World Trade Center site in New York. The World Trade Center's owner on Monday, June 30, 2008, proposed scrapping the schedule and budget for the prolonged rebuilding of the site of the Sept. 11 terrorist attacks, saying nearly every project is delayed and over budget and that previous estimates 'are not realistic.' The transit hub, once budgeted at $2.2 billion, presents some of the greatest rebuilding obstacles and now estimates for it have soared as high as $3.4 billion.
