Recently, the Shushan dual-line ship lock of the Yangtze-Huai River Water Diversion Project began trial operation, marking a significant upgrade in the capacity of the Jianghuai Canal shipping hub and providing strong support for high-quality regional water transport development.

The Shushan dual-line ship lock is the highest and largest ship lock in Anhui Province, with an annual single-direction designed capacity of 30.24 million tons.
