Need to check terminus of MO O here

While bridge:name is technically correct, I believe it should be untagged in favor of a proper bridge area tagged with man_made=bridge. Then the wikidata and wikipedia tags would make more sense moved over to that.

YY should not be secondary

MO W should not be classified this high

Classification changes from tertiary to secondary

old_ref = ref?

USPS Camdenton should probably be named "Camdenton Post Office"

Need to investigate the "not:operator:wikidata" tag, also

Many, many road names are abbreviated in Camdenton, Missouri. I fixed a few of them incidentally working on nearby state routes, but many remain

Semicolons should not go in name tag per consensus; they are accepted in alt_name, though. In any case, I would remove the "State Route X" notation altogether since ref tag (and ideally route relation) provides that

MO A should come before MO V in ref tag
