Busy expressway to Vietnam's largest airport Long Thanh widened to 12 lanes

Detailed summary

More than a year into construction, many sections of the expressway linking Ho Chi Minh City to Long Thanh airport are being widened to 10-12 lanes, with bridges and major interchanges taking shape.

The interchanges with National Highway 51 and the Bien Hoa-Vung Tau Expressway on the HCMC-Long Thanh Expressway are taking shape. The two are key traffic hubs linking Long Thanh airport to the road network of Vietnam's southeastern region.

The project to widen the HCMC-Long Thanh Expressway is about 81% complete after more than a year of work and is entering its final push to be largely finished this year.

The roughly 22-km project, which broke ground in August 2025 with a total investment of more than VND16.3 trillion (US$634 million), runs from the Ring Road 2 interchange in HCMC to the Bien Hoa-Vung Tau Expressway in Dong Nai.

Once complete, it will improve connections between central HCMC and Long Thanh airport, which is expected to begin operating at the end of this year.

At the Bien Hoa-Vung Tau Expressway interchange, contractors have largely finished compacting the roadbed and are preparing to lay asphalt on the section being widened to 10-12 lanes.

A viaduct of about 300 m running parallel to the existing HCMC-Long Thanh Expressway has most of its girders in place and is expected to be finished by the end of this year.
