Vietnam is investing nearly VND12 trillion (US$456 million) in a network of new and upgraded roads designed to connect Long Thanh International Airport with major highways, industrial zones and seaports as the country prepares to bring its largest airport into commercial operation.

Dong Nai City broke ground on three major transport projects on July 10, covering a combined 111 kilometers: the construction of Provincial Road 770B and the upgrading of Provincial Roads 769 and 773.

The Three Road Projects

Road Length Scope Estimated Cost
Provincial Road 770B ~43 km New road; six car lanes, two mixed-traffic lanes, 9.5-meter median VND4.7 trillion ($179M)
Provincial Road 773 39 km Upgrade to six or eight lanes; 80 km/h design speed VND4.3+ trillion ($164M)
Provincial Road 769 ~29 km Upgrade to at least six lanes ~VND2.8 trillion ($106M)

770BThe Largest Project

Stretching nearly 43 kilometers through nine communes and wards, it will link industrial parks in eastern and northeastern Dong Nai with the Bien Hoa–Vung Tau Expressway, the Cai Mep–Thi Vai port complex and Long Thanh Airport.

769A Key Airport Link

The route will connect National Highway 1 at the Dau Giay junction with National Highway 51 at Loc An.

773Toward Ring Road 4

The upgrade runs between National Highway 1 and Ho Chi Minh City’s planned Ring Road 4.

About Long Thanh Airport

Located about 40 kilometers east of Ho Chi Minh City, Long Thanh is being developed as Vietnam’s main international aviation hub in the south. The first phase is designed to handle up to 25 million passengers a year, while the wider project has an estimated investment of VND336.63 trillion (about $12.8 billion). Commercial operations are targeted for the end of 2026.

A Broader Economic Purpose

By connecting Long Thanh with industrial parks, logistics centers, expressways and seaports, authorities hope to ease pressure on existing routes while strengthening Dong Nai’s position as a manufacturing and logistics hub.

The projects have faced delays in previous years, largely because of land clearance and planning issues. Dong Nai authorities now aim to accelerate construction so the network can support the airport when it begins commercial flights.

Other Links to the Airport

Vietnam is also accelerating work on several other transport links to Long Thanh:

  • Ho Chi Minh City–Long Thanh–Dau Giay Expressway
  • Ben Luc–Long Thanh Expressway
  • Ho Chi Minh City’s Ring Road 3

The government has emphasized that these projects must progress in parallel so that Long Thanh does not open without adequate surface transportation.

More Than Terminals and Runways

With Long Thanh expected to become a major gateway for international traffic in southern Vietnam, the airport’s success will depend not only on its terminal and runways but also on whether the surrounding road network can efficiently move millions of passengers and large volumes of cargo.
