Why is Hefei new airport not built in the suburb of Feidong but in the suburb of Feixi?

The Xinqiao site near Liugao Town, Feixi County is 3 1.8km away from Hefei Municipal Government Square, and the site clearance is good. There are Heliuye, Hehuaifu Expressway, 365, 438+02 National Highway and Ningxi Railway passing nearby, only 3 kilometers away from Gaoliukou Expressway. In order to facilitate the city passengers to go to the airport, the airport will build a fast track to the airport. For example, according to the experience of foreign civil aviation airports, airport bus lanes will be opened in all directions from the airport to the city.
