The Government of Laos has signed a memorandum of understanding (MoU) with Phongsavanh Group to conduct a feasibility study for constructing the country’s longest expressway. The highway will connect Vientiane Capital with Xaysomboun, Xieng Khouang, Houaphan provinces, and extend to the Nam Soi border checkpoint on the Lao-Vietnam border.
Starting from National Road 13 South in Vientiane, the new highway aims to link with the existing Vientiane-Vang Vieng expressway, creating a continuous corridor that enhances connectivity between Laos, Vietnam, and China. The project was originally proposed in 2021 under a Build-Operate-Transfer (BOT) model and is currently under review by relevant ministries.
Further technical details, environmental impact assessments, and timelines will be disclosed as the feasibility study progresses under government oversight.
