The Gates, Pedro Miguel Lock, lithograph by Joseph Pennell, 1912

The Pedro Miguel lock was one of three constructed for the Panama Canal so that ships could navigate the change in levels between the oceans. Senator Mark Hanna of Ohio, who favored Panama, persuasively argued that a Nicaraguan canal would be longer, with more locks, and that engineers preferred a Panama route.
