What event made construction of canal in central America easier?

The construction of the Panama Canal was made easier by the completion of the Suez Canal in 1869. The success of the Suez Canal demonstrated the feasibility of constructing a canal through a narrow strip of land, and it also provided valuable engineering lessons that could be applied to the construction of the Panama Canal. Additionally, the technological advancements and engineering expertise gained during the construction of the Suez Canal contributed to the development of more efficient and effective construction methods for the Panama Canal.
