I might be mistaken, but I don't think this is quite true. A "covered
bridge" is a very particular kind of historical structure. You
wouldn't call a modern bridge where the footway happened to be
sheltered from the elements a "covered bridge". Anyway.

Yeah I thought so too, but if you look closer, the description here is
very specifically of a type of bridge which is part culvert, part
bridge. That is, a kind of brick structure which both has a tunnel for
water to pass through, and directly supports the roadway. (Why we
would want to specifically tag such a thing I'm less clear on...)
