From One World Trade Center: Construction Progress, one of 33 photos. One World Trade Center stands tall on the skyline of New York’s Lower Manhattan as a man takes a picture from a pier in Hoboken, New Jersey, on September 9, 2012. The price tag for the skyscraper was valued at $3.8 billion earlier this year, making it the world’s most expensive new office tower. Most of the cost overruns are due to the security measures being taken in the design of the building which sits on a site that has been bombed twice by terrorists. To offset the costs of One World Trade Center, which is being built by the Port Authority of New York and New Jersey, higher bridge and tunnel tolls have been instated and there has been a reduction in spending on transportation infrastructure. The 1,776-foot skyscraper is expected to be completed by late 2013 or early 2014.(Reuters/Gary Hershorn)
