Tongmai Special Bridge

[1] Three bridges spanning the river are situated in the same place, each from distinct historical periods.

[3] Following the breach of the dam and subsequent drainage of the lake's water, the original permanent reinforced concrete bridge and several adjacent highways were eroded, resulting in a complete disruption of traffic along the Sichuan-Tibet Southern Route.

Following 40 days of rigorous work, traffic successfully resumed on the morning of September 10, 2013.

On the morning of January 26, 2015, traffic was halted due to the displacement of the steel frame structure.

[6] The third Tongmai Bridge, also Tongmai Special Bridge, commenced operations on November 28, 2015, successfully concluding the handover and special acceptance, and officially began the trial operation phase on November 29.
