Because the geological conditions are more complicated than Jiangyin and Runyang Bridges, it is impossible to use suspension cables, and only stay cables can be used. With an investment of 6.45 billion yuan, this bridge is the largest twin-tower cable-stayed bridge in the world today. Its arduous project, huge scale, high technology and four "world's best" records make it represent the highest level of bridge construction in China and even the world, and it is called the bridge of the world, Mount Everest. The famous American National Geographic magazine made an exclusive interview and report on Sutong Bridge with the title of "Unparalleled Project", so Sutong Bridge is called "the first bridge in the world".
