You're welcome! I've been hesitating for a bit since its traffic volumes are a little low compared to other primary routes. But, like you mentioned on 5th Street and Lake Mead Blvd, a newly-built neighborhood won't receive much traffic anyway, and a road with relatively few AADT can still be classified as primary if it's the major throughfare of the area. Since you upgraded Fort Apache, I figured it was time. (Hualapai, with a similar AADT for the sections I could find, has no direct freeway connection and doesn't connect to as many amenities.)
