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.
Atlantic Bridge, Panama
The third bridge over the Panama Canal, known as the Atlantic Bridge, is a road bridge under construction in Colón, Panama, which will span the Atlantic entrance to the Canal. When completed it will be the third bridge over the Panama Canal after the Bridge of the Americas and the Centennial Bridge, both on the Pacific side of the canal.
