Historically, the most important canals are the ones that created economically valuable shortcuts for the flow of sea commerce. The most famous areThe Suez Canal in Egypt, which connects the Mediterranean Sea to the Red Sea, and therefore to the Indian Ocean. Before its construction, commercial trade either sailed around the continent of Africa or offloaded for overland transit (chiefly by rail). It was first opened in 1869.The Panama Canal, which connects the Pacific Ocean with the Caribbean Sea and therefore to the Atlantic Ocean. In many cases, this replaces the only other viable route, an often hazardous voyage around the southern tip of South America. It was constructed between 1889 and 1914.
