Q: What is the Panama Canal?

The Panama Canal is a constructed waterway that connects the Atlantic and Pacific oceans across the Isthmus of Panama . It is owned and administered by Panama , and it is 40 miles long from shoreline to shoreline. Ships can cross going in either direction, and it takes about 10 hours to get from one side to the other. Ships from any country are treated equally with respect to conditions of passage and tolls.

Q: Why is the Panama Canal important?

Before the Panama Canal was built, ships traveling between the east and west coasts of the American continents had to go around Cape Horn in South America , a voyage that was some 8,000 nautical miles longer then going through the canal and that took about two months to complete. All journeys between the Atlantic and Pacific oceans are shortened by thousands of nautical miles by going through the canal.

Q: How was the Panama Canal made?

The Panama Canal was made by building dams on the Chagres River to create Gatun Lake and Lake Madden, digging the Gaillard Cut from the river between the two lakes and over the Continental Divide , building locks between the Atlantic Ocean and Gatun Lake to lift boats to the lake and another set of locks at the end of the Gaillard Cut to lower ships, and digging a channel to the Pacific Ocean .

Q: Why does the Panama Canal need locks?

A mountain range runs the length of Panama , including through the Canal Zone , though it is lower there. In addition, the tidal levels of the oceans on either side of the Panama Canal differ. Locks raise ships to the level of the lakes (which account for about half the distance of the canal) and then lower them to sea level.

Q: Who built the Panama Canal?

A French company headed by Ferdinand, viscount de Lesseps , started to build a canal in 1881 but failed by 1889. The United States , led by Pres. Theodore Roosevelt , negotiated the Hay–Bunau-Varilla Treaty , giving the U.S. control of the Canal Zone . Work under U.S. supervision began in 1904, and the Panama Canal was completed in 1914. Tens of thousands of people, mostly labourers from Barbados , Martinique , and Guadeloupe , worked on the project.

Panama Canal, lock-type canal, owned and administered by the Republic of Panama, that connects the Atlantic and Pacific oceans through the narrow Isthmus of Panama. The length of the Panama Canal from shoreline to shoreline is about 40 miles (65 km) and from deep water in the Atlantic (more specifically, the Caribbean Sea) to deep water in the Pacific about 50 miles (82 km). The canal, which was completed in August 1914, is one of the two most strategic artificial waterways in the world, the other being the Suez Canal.
