The Panama Canal runs about 40 miles (65 km) across the Isthmus of Panama, connecting the Atlantic and Pacific oceans. Completed in 1914, it saves ships traveling between the east and west coasts of the United States up to 8,000 nautical miles (15,000 km). Between 2007 and 2016, the canal underwent a major expansion project that doubled its capacity and allowed larger ships to pass through it.
