John Stevens either.
I know a little bit about the PC...the original lock gates and the electrical control systems have been changed several times since 1914.
The original lock chambers have not been touched.
The original Panama Canal was undertaken by the same French companie that built the Suez Canal. After they failed, the Yanks went in and did it.
America could not build either the Panama Canal or the Hoover Dam if we had to start over today. Rotten mis-”education”, corrupt politics, infantile press. We are screwed.
