All three styles of Missouri markers currently in use can be found at the intersection of Missouri 116 and Missouri 371 in southern Buchanan County.
From left to right: The older style, with no border around the sign; the not-quite-so-old style with a narrow white border; and, on the rightmost 116 marker, the rectangular style that started to come into widespread use in 2000.
