Under a proposed traffic plan being developed by Airports Corporation of Vietnam (ACV) and relevant agencies, the first route from Ho Chi Minh City will follow the Ho Chi Minh City – Long Thanh – Dau Giay Expressway, cross Nhon Trach Bridge, continue along Ring Road 3, Road 25C, and Route T1 before reaching the airport.
Nhon Trach Bridge, part of Ho Chi Minh City's Ring Road 3, has already opened to traffic. Route T1, approximately 4.3 kilometers long, serves as a main access road to the airport. Construction, including road signs, lane markings, and landscaping, has been completed, and the route is now operational.
Road 25C stretches more than 14 kilometers and connects directly with Route T1. Most of the road has been developed with synchronized infrastructure, while a section of just over 2 kilometers at its starting point, connecting to T1, remains under construction. It is expected to be completed in November 2026.
Once finished, Road 25C will provide a direct link between the airport and Ring Road 3, allowing motorists to reach Ho Chi Minh City via Nhon Trach Bridge.
The second approach from Ho Chi Minh City follows the Ho Chi Minh City – Long Thanh – Dau Giay Expressway to the Long Thanh interchange, then connects to Route T2, the airport interchange, and Route T1 leading to the terminal.
This route also connects with the Bien Hoa – Vung Tau Expressway, providing additional access from eastern and southeastern areas. Route T2, approximately 3.5 kilometers long, runs parallel to both sides of the Bien Hoa – Vung Tau Expressway.
Several sections and connecting ramps along Route T2 are already open. At the airport interchange, motorists can transfer between Routes T1 and T2 and the Bien Hoa – Vung Tau Expressway.
Meanwhile, a 22-kilometer section of the Ho Chi Minh City – Long Thanh – Dau Giay Expressway, extending from the Ring Road 2 interchange to the Bien Hoa – Vung Tau Expressway interchange, is being expanded.
According to the Southern Expressway Project Management Unit, construction progress has exceeded 81 percent. Contractors are accelerating work on road surfaces, elevated sections and interchanges, aiming to substantially complete the project in 2026.
The main carriageway of the Bien Hoa – Vung Tau Expressway opened in May 2026. Component Project 1, running through Dong Nai City, has reached approximately 98 percent completion, with remaining work underway.
The Dong Nai City People's Committee issued Document No.12566/UBND-KTN, directing agencies to review construction progress and assess whether access roads, interchanges, and traffic arrangements would be ready for the airport's opening on November 3, 2026.
The city also called for traffic management plans tailored to vehicle volumes and flight schedules, along with designated passenger pickup and drop-off zones and parking areas to ensure smooth traffic flows once the airport begins operations.
