Panama Canal Construction Begins
The United States began construction of the Panama Canal after France abandoned the project

Cutting Through a Continent
The Panama Canal opened on August 15, 1914, creating a 51-mile waterway through the Isthmus of Panama connecting the Atlantic and Pacific Oceans. It eliminated the need for ships to sail around Cape Horn at the southern tip of South America — cutting journey times and distances dramatically. France attempted the canal first, beginning in 1881, but the project failed due to engineering miscalculations and devastating outbreaks of yellow fever and malaria that killed over 20,000 workers. The United States took over in 1904 under President Theodore Roosevelt, determined to succeed where France had failed.
The American Effort
American success hinged partly on defeating disease. Army physician William Gorgas led a massive mosquito eradication campaign, virtually eliminating yellow fever from the Canal Zone by 1906. This made construction viable. Chief engineer George Goethals oversaw the massive excavation — over 230 million cubic yards of earth and rock were removed, including a giant man-made lake, Gatun Lake, created by damming the Chagres River. The Culebra Cut (later Gamboa Cut) required blasting through the continental divide. About 5,600 workers died during American construction, mostly from disease and accidents, though this was far fewer than the French losses.
A Century of Global Trade
The Panama Canal transformed global shipping and trade patterns permanently. Naval strategy also shifted — the U.S. Navy no longer needed separate Atlantic and Pacific fleets to the same degree. Panama gained control of the canal on December 31, 1999, after years of negotiations with the United States. A major expansion, completed in 2016, added a third set of locks capable of handling the massive modern cargo ships that could not fit through the original locks. Today the canal handles about 14,000 ship transits annually, carrying roughly 5% of world trade. It remains one of the most important engineering achievements in human history.
