The bridge is the only bridge in the world that applied technologies of: the lower section of the pillar is constructed along with the foundation, the upper section of the pillar and the beam body are constructed independently, constructed for four railway lines and constructed with long-span. At the approach bridge section, two lines are constructed for passenger traffic line and the freight transport line respectively. The passenger traffic line is constructed 2534m long and the freight transport line is 3865.5m long. Bridge section with four railway lines is about 1301m long. The technology for main bridge section crossing the river is very complicated. The deepest section for the construction is about 47m and the highest pillar is about 80.5m high. The longest long-span of the steel structure is about 152m.
