Mostly submerged under the deep reservoir formed by the giant Changheba Dam, the Daduhe River beam bridge spent several years 210 meters above the old river level before the rock-fill embankment dam was completed in 2016. Resting on piers 116 and 87 meters tall, the 411.5 meter long structure has a 3-span configuration of 93.5 +210 +93.5 meters.
The normal reservoir level is 1690 meters making the water 185 meters deep at the crossing. The bridge allows national road S211 to connect with local country road 001 that extends east more then 50 kilometers into the mountains.
