24 sept. 1999 - Panama Canal
Description:
The project was helped by the elimination of disease-carrying mosquitoes, while chief engineer John Stevens devised innovative techniques and spurred the crucial redesign from a sea-level to a lock canal. His successor, Lt. Col. George Washington Goethals, stepped up excavation efforts of a stubborn mountain range and oversaw the building of the dams and locks. Opened in 1914, oversight of the world-famous Panama Canal was transferred from the U.S. to Panama in 1999.Ajouté au bande de temps:
