G99 Taiwan Ring Expressway
Taiwan Ring Expressway (Chinese: 台湾环线高速公路) is a proposed, hypothetical expressway encircling the island of Taiwan as part of the National Trunk Highway System of the People's Republic of China. It is currently not in existence and hypothetical due to the political status of Taiwan. The People's Republic of China claims control over Taiwan while it is currently administered and controlled by the Republic of China. Taiwan has its own highway system and does not recognize the designation by the People's Republic of China.
According to the People's Republic of China, the expressway would pass through the cities of Taipei, Hsinchu, Taichung, Tainan, Kaohsiung, Taitung, Hualian, Yilan, Keelung, before returning to Taipei.
