On March 2, 2022, China Railway Jiuqiao Bridge Engineering Co., Ltd, a subsidiary of CRHIC, participated in the construction of the world's largest span double-track ballastless track bridge - the first section of the new Nanning-Yulin Railway Baihe Yujiang Bridge in Guangxi. The precise erection on the P4 tower on the Nanning side was successful. So far, the on-site hoisting and construction of the steel box girder of the bridge has officially entered the full-scale sprint stage.

The Baihe Yujiang Bridge is a key control project of the Nanyu Railway. The main bridge is located near Baihe Town, Hengzhou City, Nanning City, Guangxi. It is 612 meters long and spans the Yujiang River. The middle span of the beam adopts steel-concrete composite beam, and the side span adopts concrete box girder. The main span is 330 meters. It is the double-track ballastless track bridge with the largest span in the world. technical foundation. The main bridge has two main towers, east and west. The tower is 146 meters high, which is equivalent to the height of a 48-story building. The main tower is a diamond-shaped structure. China Railway No. 9 Bridge mainly undertakes the production and safety tasks of the steel structure of the whole bridge.

The newly built Nanning-Yulin Railway is the first high-speed railway with a speed of 350 kilometers per hour independently invested and constructed by Guangxi. After the project is completed, the time from Nanning to Yulin will be shortened to about 40 minutes. The project will extend eastward to the Guangdong-Hong Kong-Macao Greater Bay Area in the future. The planned total length of the Nanyu-Shenzhen high-speed railway is 629 kilometers. After the completion of the whole line, the space-time distance between Guangxi and the Guangdong-Hong Kong-Macao Greater Bay Area will be greatly shortened. It is of far-reaching significance for the Hong Kong-Macao Greater Bay Area to implement the new mission of Guangxi's "three major orientations" and to achieve the goal of "two completions".
