An overview of Ground Zero on Oct. 2 in New York City. The owners of the World Trade Center site have announced that the World Trade Center memorial can be opened on Sept. 11, 2011, the 10th anniversary of the terrorist attack. It was also revealed in a 70-page report on Ground Zero's tortured rebuilding process that the rail hub will cost $3.2 billion, $700 million more than planned, and will not open until at least 2014.

The Freedom Tower won't be finished until the end of 2013.
