The Panama Canal is a waterway in Central America which joins the Pacific and Atlantic oceans. One of the largest and most difficult engineering projects ever undertaken, it had an enormous impact on shipping between the two oceans, replacing the long and treacherous route via the Drake Passage and Cape Horn at the southernmost tip of South America. A ship sailing from New York to San Francisco via the canal travels 9,500 km (6,000 miles), well under half the 22,500 km (14,000 mi) route around Cape Horn. Although the concept of a canal near Panama dates back to the early 16th century, the first attempt to construct a canal began in 1880 under French leadership. After this attempt failed and saw 22,000 workers die, the project of building a canal was attempted and completed by the United States in Panama in the early 1900s, with the canal opening in 1914. The building of the 77 km (48 mi) canal was plagued by problems, including disease (particularly malaria and yellow fever) and landslides. By the time the canal was completed, a total of 27,500 workers are estimated to have died in the French and American efforts.

Since opening, the canal has been enormously successful, and continues to be a key conduit for international shipping. Each year more than 14,000 ships pass through the canal, carrying more than 205 million tons of cargo. By 2002 about 800,000 ships had used the canal altogether.

The canal can accommodate vessels from small private yachts up to large commercial vessels. The maximum size of vessel that can use the canal is known as Panamax; an increasing number of modern ships exceed this limit, and are known as post-Panamax vessels. A typical passage through the canal by a cargo ship takes around nine hours. 14,011 vessels passed through in 2005, with a total capacity of 278.8 million tons, making an average of almost 40 vessels per day.

A brief history!

In 1878 Ferdinand de Lesseps, the French engineer who built the Suez Canal, began to dig a canal across the Isthmus of Panama, which was then part of Colombia. Tropical disease and engineering problems halted construction on the canal, but a French business (the New Panama Canal Company) still held the rights to the project. Roosevelt agreed to pay $40 million for the rights, and he began to negotiate with Colombia for control of the land. He offered $10 million for a fifty-mile strip across the isthmus. Colombia refused.

President Roosevelt once quoted he was prepared to occupy the Isthmus and proceed to dig the canal, but that he deemed it likely that there would be a revolution in Panama soon after. He was right.

The chief engineer of the New Panama Canal Company organized a local revolt. Roosevelt immediately sent the battleship Nashville and a detachment of marines to Panama to support the new government. The rebels gladly accepted Roosevelt's $10 million offer, and they gave the United States complete control of a ten-mile wide canal zone. Roosevelt ordered army engineers to start digging. Thousands of workers sweated in the malarial heat. They tore up jungles and cut down mountains. Insects thrived in muddy, stagnant pools. "Mosquitoes get so thick you get a mouthful with every breath," a worker complained. The mosquitoes also carried yellow fever, and many fell victim to the deadly disease before Dr. William Gorgas found a way to stop it.

Some Americans did not approve of Roosevelt's behavior. "There was much accusation about my having acted in an 'unconstitutional' manner," Teddy shrugged. "I took the isthmus, started the canal, and then left Congress -- not to debate the canal, but to debate me. . . . While the debate goes on, the canal does too; and they are welcome to debate me as long as they wish, provided that we can go on with the canal." Work did go on. Despite lethal landslides, workers with dynamite and clumsy steam shovels cut their way across a continent. They built a railroad, three sets of concrete locks, and a huge artificial lake. Nine years later the freighter Ancon entered the new channel. Hundreds of construction workers hopped aboard for the historic ride. A shiny towing locomotive pulled the Ancon into the first lock. Bands played and crowds cheered as the ship slipped into the Pacific.
