Building Ramps Up at World Trade Center Site

David W. Dunlap writes:

"Two years ago, it was difficult to imagine how the Port Authority of New York and New Jersey, which owns the site of the trade center and is building most of it, could ever finish the eight-acre memorial in time for the 10th anniversary of the attack, on Sept. 11, 2011. Today, it is difficult to imagine what would stop them (though, given the site's tortured history, the possibility shouldn't be completely dismissed)."

Dunlap surmises that the approaching 10th anniversary of the attacks may have prompted the quickening because of a desire to have the memorial built for the ceremonies.
