The bridge has two outer span of reinforced pre-stressed concrete box beams, which are the widest of the world for this type of bridge. The towers are located on a huge pneumatic caisson foundation system, a modern construction technology first applied in Vietnam on this project. The bridge was constructed using a balanced cantilever technology, wherein the bridge beams reaching out over the water and the aligned ends connect at a head height of 50 metres (160 ft) above the water level. This technique assured that vessels could still operate normally during the construction process.

The bridge was completed and opened for traffic on December 2, 2006. The bridge was built to address the needs of the local people and tourists, and also to complete the discontinuation of the Bãi Cháy ferry line.
