Located at kilometer 99, the alignment chosen for the Daduhe Bridge resulted in an unusual design for the east end where the anchorages had to be placed high up inside the steep mountain slope. To avoid compromising the strength of the deep underground anchorage, the engineers split the east-west lanes apart into tunnels separated by more then 100 meters, keeping the alignment off to the sides of the cable anchorage. The deck of the Daduhe Bridge is approximately 235 meters above the full lake level or 280 meters to the original level of the Dadu River.

Luding was already one of the most famous cities in Western China for its legendary chain bridge of 100 meters that ranked among the longest suspension bridges in the world since its completion in 1701. Several historic battles have taken place at or near the chain bridge due to its strategic importance, most notably during the Long March in 1935.

The Daduhe Bridge at Luding is one of at least a dozen major suspension bridges that have opened in China since 2009 that have span lengths of approximately a kilometer or longer and deck heights of 200 to 500 meters.
