China has broken ground on a 77.2-billion-yuan ($11.4 billion) project to build a second shipping channel at the Three Gorges Dam, seeking to ease a severe bottleneck on the country’s busiest inland waterway.

Construction began Monday on a project that includes two main components: a new transit channel at the Three Gorges hub and an expansion of capacity at the downstream Gezhouba Dam. Designed for 10,000-ton shipping fleets, the project is intended to relieve congestion on the Yangtze River, a critical trade artery. Its static investment estimate exceeds the 72.7-billion-yuan cost projected for the Pinglu Canal, another major waterway project in southern China.
