On August 25, 2024, Dongying, Shandong Province, welcomed a historic moment as the iconic building on the Yellow River Delta - Dongjin Yellow River Bridge, as the largest A-shaped cable-stayed bridge in the region, successfully completed its closure project.

The Dongjin Yellow River Bridge is constructed by China Railway 14th Bureau and Shandong Yellow River Engineering Group, with a total length of 1607 meters and a main bridge span of 420 meters across the Yellow River. It is a key control project of the Dezhou Road West Extension Construction Project.

This Dongjin Yellow River Bridge has not only achieved remarkable scientific research and innovation results in construction, but its achievements are also remarkable. The project cleverly utilized a high-precision monitoring and measurement system to meticulously monitor and adjust the installation of 32 pairs of inclined cables and 77 cantilever sections, ultimately achieving a "perfect and flawless" line shape when the main beam is closed. The error control achieved an unprecedented level of "key technology for the construction of A-shaped bridge towers with large inclination angles without lower beams" developed and applied in the high project. After authoritative appraisal, it has reached the standard of "leading domestically". This technological breakthrough not only demonstrates China's innovative ability in the field of bridge construction, but also has obtained 7 important patents issued by the country, including invention patents and utility model patents, fully demonstrating the scientific research strength and innovative value of the project.

The completion and opening of the Dongjin Yellow River Bridge marks a closer connection between the Yellow River Delta region and the domestic high-speed network, injecting strong impetus into the optimization of regional transportation layout. This bridge will not only effectively alleviate the heavy traffic pressure across the Yellow River for a long time, but also become a key link to promote the coordinated development of the region.
