I think it's about 10,000 years for steel bridges. There was a really good set of documentaries exploring it, called; Life After People. https://m.imdb.com/title/tt1433058/
But they hated it, because it debunked most modern crappy engineering like in those blown over skyscrapers, lasting for much less than a castle. Instead they make erratic claims of how great they're and how long they'll last. But yeah burying an IPhone and it'll be gone in a few odd decades.
Although humans have egos of gods. When they invent conjecture, those theories of their existence, they'd conqueror the universe just to insert them. You all came from apes and you all big banged. Happy now. Don't want to know. The ministry of truth has decided.
We aren't the first. Anybody denying predullivan civilization today is a moron. An extinction level event in our past. But it'll take another lifetime to correct it. Then they'll just as easily move back the monkey dates.
