Theodore Roosevelt oversaw the construction of the Panama Canal from 1903-1914 to create a shipping route between the Atlantic and Pacific oceans. Previous attempts by France in the 1880s failed due to disease and engineering problems. In 1903, the US helped Panama gain independence from Colombia and negotiated rights to build the canal. The canal cuts through the Isthmus of Panama and uses a system of locks and lakes to raise and lower ships between sea levels. It was completed in 1914 and allowed much shorter shipping times between the coasts.
