Work has commenced on a 50-km-long connectivity road between Hoa Binh and Hanoi, and the Son La expressway in Northern Vietnam. The project is estimated to cost over VND1.8 trillion and the road is scheduled to open to traffic in 2027.

However, since the cost and timeline of the project is longer than traditional expressway projects in Vietnam, the government has asked the investors and contractors to reconsider the design of the road.
