Dong Nai City, which hosts the airport, set out the arrangement in a document to the Ministry of Construction, the Ho Chi Minh City government, the Thang Long Project Management Board and the airport's investor Airports Corporation of Vietnam.
The plan covers how the North-South high-speed railway and two metros would be threaded through the corridor leading to Terminal 1.
The high-speed line would run down the center of the rail corridor. The extension of the Ben Thanh-Suoi Tien metro, reaching from Ho Chi Minh City out to Dong Nai City's administrative center and the airport, would sit on its left, while the Thu Thiem-Long Thanh metro would run on its right.

With the ground in front of Terminal 1 already crowded by access roads, viaducts, parking and other infrastructure, the city proposed offsetting the stations rather than lining them up on one axis.
