Introduction to steel cables: There are 32 pairs on each side of the bridge tower, a total of 256 steel cables, hanging the bridge deck in the air, like giant strings, playing the sonata of a dragon taking flight. The thickest cable is made of 301 high-strength steel wires with a diameter of 7 mm and weighs about 33 tons. The longest stay cable is 325 meters. The total length of the cable-stayed cables of the whole bridge is about 20,000 meters, and the total weight is about 2,900 tons.
