The Panama Canal (Spanish: Canal de Panamá) is a major ship canal that traverses the isthmus of Panama in Central America, connecting the Atlantic and Pacific Oceans. The construction of the canal was one of the largest and most difficult engineering projects ever undertaken. It has had an enormous impact on shipping, as ships no longer have to travel the long and treacherous route via the Drake Passage and Cape Horn at the southernmost tip of South America. A ship sailing from New York to San Francisco via the canal travels 9,500 kilometres (6,000 mi), well under half the distance of the previous 22,500 kilometre (14,000 mi) route around Cape Horn.
Although the concept of a canal in Panama dates back to the early 16th century, the first attempt to construct a canal began in 1880 under French leadership. After this attempt collapsed, the work was finally completed by the United States, and the canal opened in 1914. The building of the 77 kilometre (48 mi) canal was plagued by problems, including disease (particularly malaria and yellow fever) and massive landslides. As many as 27,500 workers are estimated to have died during construction of the canal.
Since opening, the canal has been enormously successful, and continues to be a key conduit for international shipping. Each year the canal accommodates the passage of more than 14,000 ships, carrying more than 203 million tonnes of cargo. By 2002 about 800,000 ships had passed through the canal.
