The expressway is operating beyond its designed capacity, leading to frequent congestion, heightened safety risks, and rising logistics costs.

The Ministry of Construction has approved a plan to study
the expansion of the Hanoi–Bac Giang Expressway from six lanes to eight to meet
rising transport demand along this key corridor.

Two expansion options are under consideration. The first
would widen the section from the National Highway 31 interchange to the end of
the expressway, covering a total length of 45.2 km. The second  involves
expanding the stretch from the National Highway 31 interchange to the junction
with the Hanoi–Thai Nguyen Expressway, with a total length of 39.5 km.

According to the national road network plan for the 2021–2030
period with a vision to 2050, approved by the Prime Minister, the Hanoi–Bac
Giang–Lang Son Expressway has a total planned length of 153 km, designed with
six lanes. The route comprises three sections: Hanoi–Bac Giang (46 km), Bac
Giang–Lang Son (64 km), and Lang Son  – Huu Nghi (43 km).

Currently, the Hanoi–Bac Giang section is operating beyond
its designed capacity, leading to frequent congestion, heightened safety risks,
and rising logistics costs. The expressway has been in operation since 2016.
