The total length of the bridge is 3118 meters, and the main span adopts a 1488 meter cable-stayed suspension cooperation system. The main tower pier is 294 meters high and is located in a 60 meter deep area. The bridge is arranged in a "highway and railway level" layout, with a railway in the middle and highways on both sides.
Strong winds, rapids, bare rocks, deep water... In order to make this large-span and heavy-duty bridge more stable in the complex marine environment, the construction unit designed 18 drilled piles with a length of 84 meters and a diameter of 6.3 meters as the foundation, so that the main tower can stand steadily on the sea.
