By the 1970s, the original airport in Taipei City — Taipei Songshan Airport — had become overcrowded and could not be expanded due to space limitations. Thus, a new airport was planned to alleviate congestion. The new airport opened (with Terminal 1) on 26 February 1979, as part of the Ten Major Construction Projects pursued by the government in the 1970s. The airport was originally planned under the name Taoyuan International Airport but was later changed to Chiang Kai-shek International Airport in memory of former President Chiang Kai-shek. The airport is the main hub of China Airlines, the Republic of China (Taiwan)'s flag carrier, as well as EVA Air, a private airline established in 1989. Overcrowding of the airport in recent years prompted the construction of Terminal 2, which was opened on 29 July 2000, with half of its gates operational; EVA Air was the first airline to move into Terminal 2. The remaining gates opened on 21 January 2005 for China Airlines, making China Airlines the only airline to operate from both terminals. The airport has announced construction plans for a third terminal. In October 2015, the design of British firm Rogers Stirk Harbour + Partners, founded by Pritzker Architecture Prize-laureate Richard Rogers, was chosen for the 640,000-square-metre (6,900,000 sq ft) Terminal 3. Over US$2.3 billion was to be spent on the project, among the most costly construction projects in modern Taiwanese history. The terminal is expected to be opened in 2026 and accommodate 45 million passengers per year, boosting the yearly capacity of the airport to 86 million passengers. Formerly known as Chiang Kai-shek International Airport, it was renamed in 2006 to its current name. The airport, originally planned as Taoyuan International Airport, bore the name of late President Chiang Kai-shek until 2006. In Chinese, its former name was literally "Chung-Cheng (Zhongzheng) International Airport", where Chung-Cheng is the legal given name that Chiang Kai-shek had used since the 1910s. In Taiwan, Chiang Kai-shek is associated with the Chinese Nationalist Party or Kuomintang and its many years of one-party authoritarian rule. Local officials in Taoyuan City and members of the Pan-Green Coalition often referred to the hub by the name originally associated with it: "Taoyuan International Airport". News organizations and local residents sometimes combined the two commonly used names as "Taoyuan Chung-Cheng Airport". The Executive Yuan of then-President Chen Shui-bian's administration officially approved the name Taiwan Taoyuan International Airport for the hub on 6 September 2006. The opposition Kuomintang, which together with its political allies held a one-vote majority in the Legislative Yuan, decried the change and proposed "Taiwan Taoyuan Chiang Kai-shek International Airport" instead. The disagreement, like those affecting the names of the Chiang Kai-shek Memorial Hall and other landmarks in Taiwan, stands as another manifestation of the Taiwan localization efforts by pan-Green officials and resistance against it by Pan-Blue Coalition.
