Bac Giang - Lang Son, the long-delayed expressway, which runs from Bac Giang Province, 80 kilometers northeast of Hanoi, to Chi Lang District in the northern mountainous province of Lang Son on the China border, was officially opened to traffic on September 29, 2019.
The 64-kilometer, VND12.19 trillion ($527 million) expressway will link up with the Hanoi-Bac Giang Expressway, and help enhance trade between Vietnam and China.
The expressway is designed to allow vehicles to travel at a speed of 100 kph. It runs parallel to the existing National Highway 1A, the 2,300-km transnational road, and will reduce the travel time from Hanoi to Lang Son by 30 minutes to two and a half hours.
