Pedro Miguel Locks, Panama Canal construction works: looking south from east. Photograph, 1910. The Panama Canal is a 48 mile ship canal in Panama that connects the Atlantic Ocean (via the Caribbean Sea) to the Pacific Ocean. France began work on the canal in 1881, but had to stop because of engineering problems and high mortality due to disease. The United States took over the project in 1904, and took a decade to complete the canal, which was officially opened on August 15, 1914. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduced the amount of time taken for ships to travel between the Atlantic and Pacific Oceans.
