First Plans of the Panama Canal

The Panama Canal


During construction, ownership of the territory that is now the Panama Canal was first Colombian, then French, and then American. The US continued to control the canal and surrounding Panama Canal Zone until the 1977 Torrijos–Carter Treaties provided for handover to Panama. After a period of joint American–Panamanian control, the canal was taken over by the Panamanian government in 1999, and is now managed and operated by the Panama Canal Authority, a Panamanian government agency.

Annual traffic has risen from about 1,000 ships in 1914, when the canal opened, to 14,702 vessels in 2008, the latter measuring a total of 309.6 million Panama Canal/Universal Measurement System (PC/UMS) tons. By 2008, more than 815,000 vessels had passed through the canal; the largest ships that can transit the canal today are called Panamax.[1] The American Society of Civil Engineers has named the Panama Canal one of the seven wonders of the modern world.
