To be clear, this road is named, but it's not a simple string name that can be canonicalized in the name tag. This is a state road designated as part of State Route 248...or Route 248, State Highway 248, Highway 248, Missouri 248, etc. That's the issue: there is not a canonical text rendering of this designation. So we use route relations to convey this and also ref tags for data consumers that don't process the route relations.
