Hoover Dam is also expected to last a long time. The forces on the structure are mainly compression and it isn't a seismically active area. The big question is whether the electricity generating turbines would fail open or shut.
What about servicing those turbines so they don't fail at all? "This dam powers our city since 4000 years." Sounds nice and Star Trek-ish doesn't it?
You can service them so they last forever as long as there are people to service them.
I'm talking about when a piece of infrastructure becomes a ruin.
Any metal parts will eventually corrode. Even if they start closed, they will eventually "open". The only parts that will remain after thousands of years are the cement parts.
For sure, but Rushmore and the Pyramids have basically no time limit. The Pyramids might get buried by the sands though.
yooo underground pyramids just like terraria predicted
