It is the largest project scale and the most complex mega bridge project in the history of bridge construction in China at that time.
The construction of Sutong Yangtze River Highway Bridge faced technical difficulties such as wind resistance, earthquake resistance, anti-punch, anti-collision, anti-corrosion. Over the years, the builders of the Sutong Yangtze River Highway Bridge have overcome four world-class construction technical problems: the permanent scour protection of the main tower pier, the construction of all 410 bored piles of the main bridge, the sinking and concrete sealing of the world's two largest steel crane boxes, and the world's largest group pile foundation project.
