The document summarizes the history and construction of the Panama Canal. It describes how the French initially tried to build a canal but failed due to financial and health issues. The U.S. then took over the project in 1903. Massive excavation efforts were required to cut through the difficult terrain, including the use of dynamite, steam shovels, and overcoming disease threats. After 10 years of construction and overcoming many challenges, the canal opened in 1914, providing a faster shipping route between the Atlantic and Pacific oceans.
