The Taichung Airport MRT (Orange Line) is an important transportation construction that connects Taichung International Airport with downtown and suburban Taichung. The MRT is planned to run along Zhongqing Road, Guogwang Road and Zhongxing Road, which are all main traffic arteries of Taichung City. It will also go along major medical institutions, universities, and business areas of Taichung city, and thus has a strong transportation demand. This construction will also coordinate with future development projects, such as “Taichung Airport 2035 Overall Plan”, “Airport Park Area”, “Shuinan Economic and Trade Park”, and the “15th Phase Land Replotting Area”. Taichung Airport MRT (Orange Line) has held feasibility study explanatory meeting from June 9 to 11, 2020 at the Daya, Dali, and North District Office. Currently, its feasibility study report has been completed and is scheduled to be filed to the Ministry of Transportation and Communication in 2021 for further examination. Taichung City Government will aggressively seek approval from the central government.
