The Three Gorges Project has been the biggest engineering works since the building of The Great Wall.
The dam, now the world's largest, is over two km. long and 185 m. high and banks up the Yangtze river for 550 km. flooding three great gorges on the river. 
A system of locks has been built so ocean going ships can t
ravel into the undeveloped interior of China. Over 1.2 million people were moved as the waters rose and new housing built for them. The dam is now functioning and has the hydro electric equivalence of 18 nuclear power stations.
In Yichang, down with the old and up with the new!
