The navigable canals of the world connect lakes, seas, and rivers. They offer shorter transport routes through some of the world’s most important commercial regions, and they end up saving everyone significant time and money from producers, shippers, and consumers. 

Following are 25 of the world’s most important shipping canals. They range from less than 4 miles long to over 1,000, and some are now bigger tourist attractions than transport passages. However, all have played a vital role in enabling ship transport, and many still do.

1. Panama Canal

Arguably the most famous canal in the world, this Central American waterway in Panama connects the Atlantic and Pacific Oceans. Before its existence, ships traveling between the east and west coasts of the U.S. had to go all the way around the tip of South America. Now, this 51-mile waterway shaves more than 9,000 miles off that trip.

2. Suez Canal
