The construction of the Daduhe Extra Large Bridge on the Yalin section of the Sichuan Tibet Railway began at the end of 2020, with multiple mixing stations from Fangyuan Group participating in the construction project.

The newly built Dadu River Extra Large Bridge on the Sichuan Tibet Railway is the first bridge for the Sichuan Tibet Railway to enter Tibet. The bridge is located on the Dadu River in the revolutionary holy land of Luding County, Sichuan Province, and is the longest and most difficult bridge project in the entire line. It is also the longest and technically complex mountain railway suspension bridge in China
