New Three Gorges Water Transport Corridor: 76.6 billion super project to solve the bottleneck of Yangtze River shipping

The Three Gorges Water Transport New Corridor project has a static total investment of 76.6 billion yuan and a total construction period of 100 months, including two parts: the Three Gorges Hub New Corridor Project and the Gezhouba Shipping Expansion Project. The project will build a new waterway of more than 6,000 meters on the north side of the existing Three Gorges Lock, using a double-line continuous five-stage lock scheme, and designed to pass 10,000-ton ships to alleviate the congestion problem of long-term overload operation of the Three Gorges Lock. The Gezhouba shipping capacity expansion project plans to demolish the existing 3,000-ton No. 3 lock and build two new lines of 10,000-ton locks to comprehensively improve the navigability of the Yangtze River's golden waterway7.

Investment in water conservancy infrastructure continues to increase, and the scale may reach 1.5 trillion yuan in 2025

In recent years, the scale of investment in our country's water conservancy construction has continued to rise, exceeding one trillion yuan (1,089.3 billion yuan) for the first time in 2022, reaching 1,199.6 billion yuan in 2023, and further increasing to 1,352.9 billion yuan in 2024. According to industry forecasts, investment in water conservancy construction is expected to exceed 1.5 trillion yuan in 2025, a record high. In this context, the construction process of the new Three Gorges Water Transport Corridor, as a national key water transport infrastructure project, has attracted much attention. The successful landing of the substation project marks that the project has officially entered the construction stage, and more bidding sections will be launched in the future.

This bid not only demonstrates the competitiveness of the Fourth Bureau of China Hydropower in the field of large-scale water conservancy projects, but also lays a solid foundation for the smooth progress of the new Three Gorges water transport channel. After the completion of the project, it will greatly improve the efficiency of Yangtze River shipping and help the high-quality development of the Yangtze River Economic Belt.
