The Hanoi - Bac Giang expressway has been proposed to expand from current six lanes to 10, instead of 8 lanes as initially projected expansion scheme, to deal with rising traffic volume.

Investment will be made in the form of public-private partnership (PPP), according to the proposal submitted by the Hanoi-Bac Giang BOT JSC, the investor of the expressway.

The expressway is operating beyond its designed capacity, causing frequent congestion, safety risks, and higher logistics costs, according to the company.

The expressway currently sees more than 53,000 vehicles daily, on average, exceeding its designed capacity. Traffic volume has increased by around 11% annually over the past three years.

Under the road network plan for 201-2030 period with a vision to 2050, which was approved by the Prime Minister, the Hanoi – Bac Giang – Lang Son expressway has a total length of 137km with six lanes. Of which, the Hanoi – Bac Giang section, which also runs through Bac Ninh province, is 46 km long and is initially projected for expansion to eight lanes.
