Fifty miles long, the awesome Panama Canal takes ships eight hours to transverse (and often costs them toll fees of over $100,000). A system of locks and manmade lakes rely on gravitational forces to lift the giant boats over the Panama isthmus -- ships rise as high as 85 feet over sea level -- and set them down again on the other side. The French began construction of the canal after their successful completion of Egypt's Suez Canal, but yellow fever, other diseases, and the difficulty of excavating rock from the middle of the jungle caused them to abandon the project. American President Theodore Roosevelt then took over the project through controversial political maneuvering, and the canal was finally opened under American control in 1914. Ownership passed back to the Panamanians in 1999, and in their hands the canal has consistently exceeded all previous traffic, revenue, and safety records.

Huge ships can be seen transiting across the ocean, the canal is a water bridge that links the Caribbean Sea to the Pacific Ocean.
