The Chengjiang Tunnel in Yuxi section of the Yunnan Central Water Diversion Phase II supporting project, undertaken by China Railway First Group, has been successfully completed. The geological conditions of the tunnel are complex and the construction risk is high. After completion, it can provide water supply to the Chengjiang area every year, help protect the ecological environment of Fuxian Lake, and build a strong regional water safety barrier.
