Completion announced of record-breaking span

TY Lin International (TYLI) has announced completion of the world's longest box girder span, the 330m-span Shinanpo Bridge in Chongquin, China. Some 30,000 firecrackers were let off during a 30 minute display to mark the completion. TYLI designed the bridge which stands 25m from an earlier crossing of the Yangtze River. The new bridge is 19m wide and 1,103.5m in total length. The entire bridge was built using a cast-in-place concrete free cantilever segmental method, with the exception of a 103m section in the middle of the main span, which is a steel box. The steel box element was incorporated into the design to reduce the bending moment and shear of the structure and make the long span technically and economically efficient.

Important Update: Bridge Design & Engineering Magazine


For more than 31 years, Bridge Design & Engineering has been a trusted source of new insights, knowledge, and connections for the global bridge community.  With the rapid shifts in the publishing landscape and increasing costs, sustaining the printed magazine at the high level of quality our readers expect has become increasingly challenging.  After careful consideration, Hemming Group Ltd has made the difficult decision to discontinue the print publication.


You will continue to have full access to the Bridge Design and Engineering website - including the complete archive. Although the site will no longer be updated, the archive remains a rich resource of engineering knowledge and project insight.  You can also continue to access the Bridge Directory, IBIG, through the website or directly at: https://www.bdeibig.com/


While this marks the end of an era, it also opens a new chapter, one focused on strengthening the connections, collaboration, and technical excellence that our community thrives on.  Our energy and investment will now be directed toward expanding and enhancing our industry leading events that bring the bridge community together.


Our flagship events Bridges and Bridges Scotland will continue to thrive as essential annual gatherings for bridge owners, managers, designers, engineers, and suppliers.  These events play a vital role in sharing innovation, showcasing best practice and emerging technologies, and fostering meaningful collaboration across the industry.  We are excited to build on their success and will further develop these events in the years ahead.
