With a central span of 440 meters, the Daduhe Bridge Shaba is one of the 20 longest span arch bridges in the world. The 4-lane crossing is one of two spectacular arch structures on the 97 kilometer Luding to Shimian expressway that was built to accommodate the lake formed behind the massive 210 meter tall Dagangshan Dam.

Just 10 kilometers to the south on the same expressway is the Daduhe Bridge Tianwan with an equal sized CFST through arch span of 440 meters but even higher at 175 meters.

Also to the south are 2 large beam bridges that cross over tributaries of the Dadu River at a height of 155 meters though most of that is also hidden below the deep reservoir behind the Dagangshan Dam.

The main arch was constructed using the stayed cantilever method whereby a tower is erected on either side of the gorge and cables temporarily radiate out from it to support individual sections of the arch until the two halves can be joined in the middle. A cable high line between the tops of the two towers was used to move the steel sections into place high above the river. Like all of Chinese CFST arches, once the arch was closed, concrete was pumped into the 8 main ribs of the arch span, stiffening and strengthening the entire structure.
