Recently, the last section of the prefabricated pier of the Hangzhou Bay Cross-Sea Railway Bridge of the Tongsu-Jia-Ningbo High Speed Rail was completed, marking the complete completion of the substructure of the sea-salt section of the bridge. This is also the first time in the world that the prefabricated pier process has been successfully applied in the field of cross-sea railway bridges. It is not only a major breakthrough in China's cross-sea railway bridge construction technology, but also accumulating successful experience for similar projects in the future. Currently, the total progress of the Haiyan section of the Hangzhou Bay Cross-Sea Railway Bridge is over 80%. The Northern Channel Bridge is scheduled to reach Helong in September, and the entire bridge is expected to be ready for traffic by the end of 2027.
