When people decided to build things back in the day, they built them to last forever!
I'm always kind of fascinated when stories like this pop up because it just shows the workmanship that used to go into civic projects. Now it's build it fast, get it done, useful life 40-50 years until we have to do it over again.
But here is a sewer structure that is damn near 150 years old and only now is fatigued to the point of breaking. Never mind that in 1866 or 1870 no one could imagine a 20,000 pound cement truck lumbering down Jefferson street on top of this structure. And...the structure held, with millions upon millions of cars, trucks, busses, and more passing over top of it.
Wouldn't it be nice if the new I-475 project, scheduled to F things up for 3 years, was built as well as this was?
