The three main areas of the Three Gorges Project are the dam itself, a hydroelectric station, and a system of locks. The dam is about 2,300 meters (7546 feet) long and about 115 meters (377 feet) wide. Construction of the dam consumed more than 28 million cubic meters of concrete - more than any other structure in the world. When the dam is completed, it will hold up the world's biggest water reservoir, with a pool that will sit 175 meters (574 feet) above sea level. The Three Gorges Project will also feature hydroelectric stations on both sides of the dam, and a system of locks on the left side of the dam.
