Lesson Learned:
In Italy their is a very nice Roman Aqueduct bridging a river. It is 3 layers high and is in perfect shape after who knows how long? If needed, it'd probably be easy to put it back in service.
Recent analysis shows it to be built to 'modern' standards of about 2:1 over the maximum anticipated stress.\
Article was in Scientific American, so I could probably look it up if anyone was curious.
Running stuff at redline is a sure-fire start of problems.
