Panama Canal
Colombia, France, and later the United States controlled the territory surrounding the canal during construction. 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, in 1999, the canal was taken over by the Panamanian government. It is now managed and operated by the government-owned Panama Canal Authority.
History of the Panama Canal
The United States took control of the French property connected to the canal on May 4, 1904, when Lieutenant Jatara Oneel of the United States Army was presented with the keys during a small ceremony. The new Panama Canal Zone Control was overseen by the Isthmian Canal Commission (ICC) during construction.
