Freedom Tower Construction Finally Begins

(Portions from Wikipedia)

Rebuilding at the World Trade Center site in Lower Manhattan began this week, nearly 4 and a half yars after the Twin Towers were destroyed by the worst terrorist attack in American history. The project had been delayed due to acrimonious disputes over money, security and design but the last major issues were resolved on April 26th, 2006 with a deal between developer Larry Silverstein and the Port Authority of New York and New Jersey.

The site will include three other high rises plus a residential tower that will surround a memorial, museum and cultural center dedicated to what relatives of the September 11 victims consider a sacred site.

Construction is scheduled to be finished by 2011 or 2012. As reported by the developers of the Freedom Tower, the skyraper will rise 1368 feet into the air.
