Square covers like this are common globally. AFAIK also in the US:

Setting square tiles or paving stones around a circular cover is a pain in the ass.

But it wouldn't be the first time the US is weird, like the whole imperial measurements thing, so whatever. Or maybe you live in a state that decided square manhole covers were biblically incorrect.
