It's reminiscent of "Business 13" in Branson West. In this case, Camden County and/or the City of Camdenton has named the western half of the route "North Business Route 5" and the eastern half "South Business Route 5".

It's possibly worth tagging with a route relation, but there's no special shield or banner for it. It is not a state business route, and it does not belong to the US:MO:Business network.
