the unsung tunnel that lets water cross under roads instead of eating them
means A culvert is a pipe or covered channel that carries a stream or drainage water beneath a road, railway, or embankment.
from The word surfaced in English in the late 18th century, but its deeper roots are genuinely murky — etymologists shrug. It has no convincing Latin or French ancestor on record, and the various charming guesses (a mangled French phrase, a builder's name) are all unproven. Honestly, it's one of those engineering terms that seems to have bubbled up from the trade itself, its origin lost in the mud it was built to drain.
