1, China's largest highway bridge, designed for day and night traffic of 120,000 vehicles, under the bridge can pass 100,000 tons of giant ships.
2, China's first orthotropic anisotropic plate steel box girder suspension bridge, orthotropic anisotropic plate refers to the bridge deck plate in the direction of the transverse bridge and along the direction of the bending stiffness is different. The main cables of this bridge are made of galvanized cold-drawn high-strength steel wires. The steel wires are arranged in parallel.
3. The main span of this bridge is 888 meters, which is the first longest in China. The main span is the distance from the bank on the Humen side to the Hengshou Island in the center of the river.
