Bach Dang Bridge (VN2021), a multi-span cabled-stayed bridge in Vietnam

The Bach Dang Bridge is the first all-Vietnamese designed and constructed mega infrastructural project located in northern Vietnam. The project is estimated to cost 7.3 trillion VND (approximately 312.2 million USD). The 5.4-kilometer bridge spans over the historic Bach Dang River and is part of the Hanoi–Quang Ninh highway project. It also features 4 lanes of 28 meters wide, meticulously designed for speeds of up to 100 km/hour traffic. The bridge and highway connection are intended to help shorten the distance from Hanoi and Quang Ninh from 175 km. to 125 km., as well as to cut travel times between the two localities in half.

ベトナム初の多径間斜張橋の建設

The very first made-in-Vietnam multi-span cabled-stayed bridge features 3 H-pylons, representing Hanoi, Hai Phong, and Quang Ninh urban areas. These regions are now connected by the bridge to boost their economic growth. Bach Dang River has a historical significance as it is the site of the Battle of Bach Dang in 938CE, where rebel Vietnamese forces defeated and put an end to the Chinese imperial domination of Vietnam. Bach Dang Bridge will only further enhance the strategic edge of the northern region.
