This sign gantry for westbound traffic on US 60 at US 67 and Business US 67 in Poplar Bluff omits the fact that Business US 60 is also at this interchange. However, this isn't a goof, but the usual Missouri practice. If a business route would "backtrack" through a city, Missouri usually does not provide a sign for the route. In other words, there was a previous interchange or intersection for westbound traffic to access Business US 60, so Missouri does not usually provide a sign for the subsequent intersection with the business route and its parent route.
