As part of the World Bank–funded Vietnam Road Asset Management Project (VRAMP), the sub-project aims to upgrade the section connecting Moc Chau town with Son La City.

The project has a total investment of US$301 million, including US$251 million from World Bank loans and US$50 million from domestic capital.

In addition to National Highway 6, VRAMP will also focus on upgrading and maintaining several key roads under the transport network in the northern key economic area, such as Highway 2, Highway 38, Highway 38B, Highway 39 and Highway 48.

National Highway 6 is the main road connecting the Northwest Region and Hanoi. Once completed, Highway 6 will help shorten travel time between Hoa Binh and Son La, meeting the growing transport demand on the route and facilitating socioeconomic development and national defence and security for the Northwest Region in particular and the North in general.
