Tan Son Nhat International Airport, Ho Chi Minh City's gateway by air, will be connected directly to downtown by metro. The plan the city unveiled on July 27Metro Line 6のタンソンニャット〜フーフー区間は、約23kmのうち19kmを地下に通し、第1〜第3ターミナルすべてを地下駅で結ぶ。年内着工、2030年完成を目指す。渋滞が慢性化する空港周辺で、在住者の通勤も出張者の空港アクセスも変わる計画だ。
19 of 23 km underground; ST02 and ST03 connect all three terminals
計画ではこの区間は約23kmで、うち約19kmが地下区間。6号線そのものは市内をまわる環状線で総延長は約53.8kmとされ、今回の約23kmはその第1段階にあたる。駅は地下13駅と地上系4駅の計17駅で構成される。核となるのが空港直下のST02・ST03の2駅で、この2駅がタンソンニャット空港の全3ターミナルを地下でつなぐ。到着後にスーツケースを引いて炎天下のタクシー乗り場に並ぶ、という現在の動線が、駅まで屋内で完結する形に変わる。車両は最高時速80〜110kmで、開業時は3両編成、需要増に応じて6両まで増結できる設計とされる。
Connecting with Line 1 at ST12, one transfer takes you to the city center
Line 6's real value lies in stitching the airport into other lines, existing and planned. The connections shown in published materials are as follows.
| Connections | Connecting station | The route's character |
|---|---|---|
| Line 2 (Ben Thanh-Tham Luong) | Ba Queo Station | The trunk line connecting the city center with the northwest |
| Line 4 (Dong Thanh – Hiep Phuoc) | ST03 | A planned line running north–south |
| Line 1 (Ben Thanh–Suoi Tien) | ST12 | The main eastbound line already in service |
| Thu Thiem-Long Thanh railway | Beyond ST16 | The rail link to the new Long Thanh Airport |
The connection with Line 1 matters most. Line 1, running Ben Thanh-Suoi Tien, is already in service, and once Line 6 links up at ST12, you'll be able to reach the airport from the city center with a single transfer.
A separate line from "Line 2's localization"—to avoid confusion
As for Ho Chi Minh City's metro, the domestic localization of Line 2's technology drew attention in July. For details, seeHo Chi Minh City's Metro Moves Toward Local Production: MOU on Technology Transfer Signed for Line 2, but that was about the Vietnamese side domestically producing the rolling stock and systems for the existing Line 2—a separate track from this new Line 6. The city is advancing several lines in parallel, so sorting out 'which line, and what about it' makes the big picture easier to follow.
Late-night and rainy-season airport trips, once taxi-only, are set to change
For now, getting from Tan Son Nhat to the city center means mainly taxi or Grab, and mornings and evenings get caught in congestion around the airport. Reading a trip to Ben Thanh as 30 minutes only for it to take an hour is a common experience for residents. If Line 6 links all terminals underground, it will create a punctual route less affected by weather or traffic. For trips with large luggage, during rainy-season downpours, or on late-night and early-morning flights, it adds a rail option that spares you the stress of haggling over fares. Hanoi, too, has begun breaking ground on several lines at once, and the full picture isHanoi breaks ground on five lines at once-will airport access really change?covered it. In both cities, the effort to link airport and downtown by rail has moved from the "planning" stage to "construction."
Set for completion in 2030, designed to connect with the Long Thanh link railway
Completion is set for 2030, and the current airport access will remain for the years until then. How to use it alongside the new Long Thanh Airport, due to open in December 2026, will also become a point of discussion. Long Thanh's role isGiant Long Thanh airport opens December 1: how to use it alongside SGN?we've laid it out. The fact that Line 6 also connects with the Thu Thiem–Long Thanh railway points to a future in which the two airports are tied together by rail. Underground stations directly beneath the airport will also redraw the map of nearby real estate and commerce, and are expected to ease congestion around Tan Son Nhat, which sits close to the city and has had little room to expand. Land acquisition and financing could shift the timeline back and forth, but the framework of connecting every terminal reflects how serious the city's transport plan is. Business travelers and residents who visit Ho Chi Minh City repeatedly would do well to track the progress and start picturing now which terminal to use and how to get through it—so getting around will be a lot easier once it opens.
