The bridge forms part of the G4216 Chengdu–Lijiang Expressway carrying traffic over the Jinsha River.
The bridge construction began in 2016, the structure closed in January 2020[2] and it opened for traffic on 31 December 2020.
[4] The bridge crosses the river 1.4 km upstream from the Jin'anqiao Dam.
Due to the formation of the reservoir behind the dam, the full clearance to the original river level will not be visible.
The original design was slightly higher crossing 512 m (1,680 ft) above the river and slightly shorter with a main span of the bridge 1,190 m (3,900 ft).
