Ling Bridge, built by Siemens AG in 1936, is the only existing three-hinged steel arch bridge in China, and now declared a historic structure by the local government. Located on the busiest road that crosses the Ningbo city centre, the bridge has carried heavy traffic for more than 70 years. Concerned about the bridge's safety following frequent ship collisions in recent years and other damage, the bridge owners perform structural inspections every year. According to the latest inspection, Ling Bridge is suffering from a number of serious structural problems, including local deformation and deflection of the arch ribs, cracks in the deck and severe corrosion of the hangers. Therefore, at the end of 2014, the bridge management launched an overhaul of the bridge.
