Consequently, as the scope and design of the WTC have evolved, particularly in response to the national symbolic objectives and security concerns that have permeated the development, the required costs of rebuilding have correspondingly expanded. The objective of completing the Memorial by the ten‐year anniversary of September 11 became a public mandate to reflect the profound national symbolism of the WTC’s timely resurrection. To meet this timeline, the Port Authority had to incur significant costs related to the acceleration of the WTC construction program. The level of dedication by the Port Authority, from daily involvement of certain members of its Board of Commissioners, to on site construction personnel, has been unwavering. By the time of its completion, in addition to third party funding, the Port Authority will likely spend over $ billion dollars of its own capital in this historic endeavor. The recent opening of the Memorial on September 11, 2011 marked the end of an extraordinarily difficult decade for the agency and the beginning of a new chapter in its history. .
