People walk past One World Trade Center, the central skyscraper under construction at Ground Zero, on January 30, 2012, in New York City. The price tag for One World Trade has recently been valued at $3.8 billion, which would make 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 at the end of 2013.
