How? Netherlands soil must’ve been salted to hell and back or something.
Brb if I’m not back from a wikipedia rabbit hole in 2 hours, keep on going without me
Preserved in peat, I believe!
Yes, from this r*ddit post:
A 4,573-year-old neolithic wooden peat road near Nieuw-Dordrecht, in the Netherlands, excavated in the 1980s. The peat road was at least 800 metres long, and its construction has been precisely dated to the year 2,549 BC thanks to dendrochronology or tree-ring dating

There’s mainly just a couple ways to keep things from degrading over long periods, but they mostly have to do with controlling the growth of microbes.
You can do this by controlling moisture, access to oxygen, or modifying things like the pH of the environment. If I’m not mistaken, I believe peats tend to be highly acidic and oxygen deprived.
Probably the foundation for a road, just like we drive on rebar.
I mean, isn’t a lot of the Alaskan highway built like this?
