Reported to be 216 meters high from deck to original river level, the Liutonghe Route S307 Bridge is one of several high beam bridges that were completed to raise the level of local road S307 to the upper slopes of the Jinshajiang (Yangtze) river to avoid being submerged under the lake formed from the completion of the Xiluodu Dam. With a height of 285.5 meters, Xiluodu is the 3rd tallest concrete dam in the world and is located on the border of Sichuan and Yunnan Provinces.

Completed in 2024, the parallel Liutonghe arch bridge on the G4216 Yibin to Panzhihua Expressway overshadows the older beam bridge with a height of approximately 290 meters.

The Liutonghe Bridge piers are 125 meters tall.
