The Panama Canal connects the Atlantic and Pacific Oceans via the Isthmus of Panama, providing a shortcut between the oceans. Construction began in 1881 under French leadership but was abandoned after thousands of worker deaths. The United States took over the project in 1904 and opened the canal in 1914 after overcoming challenges like building giant locks and cutting a path through tropical jungle. The canal was an important engineering feat that shortened shipping times and benefited international trade.
