The Panama Canal is an artificial hydraulic work that crosses the Isthmus of Panama in Central America. 81 kilometers long, including extensions at sea, connects the Atlantic Ocean with the Pacific Ocean. It consists of two lifts and descents that are located between the Bay of Limón and Lake Gatún (Atlantic side) and in the villages of Pedro Miguel / Miraflores (Pacific side). Each of the two systems is made up of 6 basins placed at three to three on two different ways with jumps of a level of about 9 meters between each of them, allowing the ships to overcome a total difference in height of about 28 meters. The canal avoids ships going from ports of the Pacific to those of the Atlantic and vice versa the circumnavigation of South America. The mouthpiece at the Caribbean Sea is located adjacent to the port of Cristóbal in the Bay of Limòn. The ships coming from the Atlantic and directed to the Pacific, after having traveled the ski lift consisting of the three Gatún locks, cross the Gatún lake, the Gamboa area, the Culebra strait, then come to the Pedro Miguel lock, they pass then, after a first level jump of about 9 meters, in the lake of Miraflores that gives access to the two locks of Miraflores reaching at the exit of these the sea level at the port of Balboa. Follow the navigation passing the bridge of the Americas until you reach the Gulf of Panama. The canal is crossed by thousands of ships per year for a tonnage of tens of millions of tons in both directions. Because of the particular conformation of the Panama isthmus in the Canal area (which does not follow the northwest-southeast trend but bends in the southwest-northeast direction) the entrance to the Atlantic Ocean is further west than the Pacific. A ship that passes from the Atlantic to the Pacific will then exit the Channel at a point more eastern than the entrance, although it is such an ocean. The original project of the canal dates back to the nineteenth century; in 1879 it was advocated by the International Congress of Paris and had among its promoters Ferdinand de Lesseps, already builder of the Suez Canal.
