At 9:00 AM on April 14, the key phase of an underpass renovation beneath the Guangda Railway was successfully completed. A 2,500-ton prefabricated frame bridge was installed using an advanced “prefabrication + jacking” method, precisely moved into place after 24 hours of continuous work.⁣ ⁣ The original culvert was replaced seamlessly, with railway operations resuming immediately after completion.⁣ ⁣ #Infrastructure #Engineering #China #Railway #Construction
