The site is being rebuilt with six new skyscrapers, a memorial and museum to those killed in the attacks, and a transportation hub. One World Trade Center, the tallest building in the United States, is the lead building for the new complex, reaching more than 100 stories upon its completion in November 2014. The original World Trade Center featured landmark twin towers, which opened on April 4, 1973, and were the tallest buildings in the world at their completion. The other buildings in the complex included the Marriott World Trade Center (3 WTC), 4 WTC, 5 WTC, 6 WTC, and 7 WTC. They were destroyed on the morning of September 11, 2001, when Al-Qaeda-affiliated hijackers flew two Boeing 767 jets into the complex in a coordinated act of terrorism. At 8:46 A.M. Eastern Time (ET), a team of five hijackers intentionally crashed American Airlines Flight 11 into the northern facade of the North Tower. At 9:03 A.M. ET, a second team of five hijackers intentionally crashed United Airlines Flight 175 into the southern facade of the South Tower. After burning for 56 minutes, the South Tower collapsed at 9:59 A.M. At 10:28 A.M., the North Tower collapsed, after burning for 102 minutes. The attacks on the World Trade Center killed 2,753 people. The resulting collapse caused structural failure in many of the surrounding buildings as well. The process of cleaning up and recovery at the World Trade Center site took eight months, after which rebuilding of the site commenced. After years of delay and controversy, reconstruction at the World Trade Center site is now underway. The new complex includes One World Trade Center (formerly known as the Freedom Tower), 7 World Trade Center, three other high-rise office buildings, a museum and memorial, and a transportation hub similar in size to Grand Central Terminal. One World Trade Center was completed on August 30, 2012, and the final component of its spire installed on May 10, 2013. 4 World Trade Center opened in November 2014.〔(【引用サイトリンク】title=Lower Manhattan : 1 World Trade Center )〕 The 9/11 memorial is complete, and the museum opened on May 21, 2014. 3 World Trade Center and the Transportation Hub are also making progress, and are set to be finished by around late 2017 and late 2015, respectively. 2 World Trade Center's full construction was placed on hold in 2009; however, on June 9, 2015, it was reported that the building would undergo a new design, led by architect Bjarke Ingels of the Bjarke Ingels Group (BIG). It was also reported that the newly designed 2 World Trade Center would become the headquarters for Rupert Murdoch's 21st Century Fox and News Corp. If approved, the new building would be completed by the 20th anniversary of September 11, 2001. ==Cleanup== (詳細はFresh Kills Landfill on Staten Island, where it was further sifted.〔(【引用サイトリンク】url=http://statenisland.pastperfect-online.com/00039cgi/mweb.exe?request=keyword;keyword=fresh%20kills%20recovery;dtypewanted=;dtype=d )〕 On , 2002, a ceremony was held to officially mark the end of the cleanup efforts. In 2002, ground was broken on construction of a new 7 WTC building located just to the north of the main World Trade Center site. Since it was not part of the site master plan, Larry Silverstein was able to proceed without delay on the rebuilding of 7 World Trade Center, which was completed and officially opened in ; this had been considered a priority since restoring Consolidated Edison Co.'s electrical substation in the building's lower floors was necessary to meet power demands of Lower Manhattan. While 7 World Trade Center was not part of the master plan for the Twin Towers site, Silverstein and Con Edison recognized that the rebuilding of 7 World Trade Center would have to be consistent with the master plan which was expected to re-open the street grid which had been blocked by the original World Trade Center super-block. As a result, the design for the new 7 World Trade Center allowed for the re-opening of Greenwich Street, which had been blocked by the original 7 World Trade Center.〔(【引用サイトリンク】title=Experts Discuss Planning, Designing and Rebuilding World Trade Center )〕 A temporary PATH station at the World Trade Center opened in , pending replacement by a permanent station designed by Santiago Calatrava. With the main World Trade Center site, numerous stakeholders were involved including Silverstein and the Port Authority, which in turn meant that George Pataki, the then-Governor of New York, had some authority. In addition, the victims' families, people in the surrounding neighborhoods, Mayor Michael Bloomberg, and others wanted input. Governor Pataki established the Lower Manhattan Development Corporation (LMDC) in as an official commission to oversee the rebuilding process. The LMDC held a competition to solicit possible designs for the site. The Memory Foundations design by Daniel Libeskind was chosen as the master plan for the World Trade Center site.〔(【引用サイトリンク】author=Lower Manhattan Development Corporation )〕 The plan included the Freedom Tower (now known as ''One World Trade Center'') as well as a memorial and a number of other office towers. Out of the World Trade Center Site Memorial Competition, a design by Michael Arad and Peter Walker titled ''Reflecting Absence'' was selected in .〔 〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「World Trade Center (2001–present)」の詳細全文を読む スポンサード リンク
