In a report to the prime minister, the ministry said the projects would form part of the 2026-2030 public investment plan to expand Vietnam's expressway network in line with the national transport strategy through 2050.
Priority projects include western sections of the North-South Expressway, an expressway linking Ho Chi Minh City with the Mekong Delta, expanding the Hanoi-Bac Giang Expressway and widening the eastern North-South Expressway.
The ministry also proposed several east-west expressways linking mountainous areas with seaports and border crossings with Laos and Cambodia to improve regional connectivity and cross-border trade.
The 12 projects are estimated to cost VND 514.9 trillion in total, of which VND 334.6 trillion would come from the state budget during the 2026-2030 period.
The ministry urged the government to allocate funding under the next medium-term public investment plan so construction could begin as soon as possible to support economic growth.
