Panama Canal
France began work on the canal in 1881, but stopped due to engineering problems and a high worker mortality rate. The United States took over the project in 1904 and opened the canal on August 15, 1914. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduced the time for ships to travel between the Atlantic and Pacific Oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan.
History of United States foreign policy
The opening of the transcontinental railroad in 1869 made travel to California fast, cheap and safe. Americans lost interest in canals and focused their attention on building long-distance railways. The British, meanwhile, turned their attention to building the Suez Canal through Egypt. London maintained a veto on on American canal building in Nicaragua. In 1890s, the French made a major effort to build a canal through Panama, but it self-destructed through mismanagement, severe corruption, and especially the deadly disease environment. By the late 1890s Britain saw the need for much improved relations with the United States, and agreed to allow the U.S. to build a canal through either Nicaragua or Panama. The choice was Panama. The Hay–Pauncefote Treaty of 1901 replaced the Clayton–Bulwer Treaty, and adopted the rule of neutralization for the Panama Canal which the U.S. built; it opened in 1914.
