How did the panama canal exemplify american technological prowess?

The work required to build the Panama Canal was initiated by France in 1881. However, France abandoned the project as the engineering problems were too difficult and the mortality rate was very high. The United States continued the work in 1904, and finished the project in 1914. This was seen as evidence of the American technological prowess. The work was extremely difficult to complete, as the project was one of the most difficult engineering projects ever attempted.
