The expressway is planned for expansion to 10-12 lanes with total estimated investment of VND22 trillion ($836 million).

Hanoi’s Phap Van – Cau Gie Expressway – part of Vietnam’s North-South highway system,  is planned to be expanded to 10–12 lanes under a public–private partnership (PPP) model to meet rising transport demand and ease congestion.

The Ministry of Construction has assigned Phuong Thanh Investment and Transport Construction JSC to conduct a feasibility study for the expansion project, which has a total estimated investment of VND22 trillion ($836 million).

According to the ministry, the project proposal must be submitted to competent authorities for consideration in the second quarter of 2026.

The 29-kilometre expressway, which currently has six lanes and a roadbed width of 33.5 metres, serves as a key gateway connecting Hanoi with central and southern provinces.
