When can the second-class shiplock of Three Gorges be excavated?

The excavation of the second lock of the Three Gorges Project has been in the discussion stage, but the construction has not yet officially started. Although the plan has been formed, the cost and time of large-scale mountain excavation are not a problem. The question is whether large-scale excavation will affect the safety of the existing Three Gorges Dam, and no one is sure.

Although the specific time for excavating the second ship lock has not yet been determined, in the long run, it is of great significance to improve the shipping capacity of the Yangtze River, especially the logistics and transportation in the central and western regions.
