My grandma’s mountain village is located just below some big hydro dam (the second biggest in my country, Romania), built in the early 1960s. So that gives the authorities (or whoever will actually own that dam at that point) another 40 years to either tear it down completely for safety reasons (I don’t see that happening, the incoming money is too good) or to tear it down and build a similar one in its place (I also don’t see that happening, to be honest).
And this is, comparatively speaking, a happy case, I’m sure there are lots of big dams built back in the 1930s in places like the US or the former USSR that are only 10 or so years from that “this concrete-structure is only guaranteed to last 100 years” time-point.
