I only made it a primary because it handles the combined traffic of highways M-22 and M-72, which oftentimes matches the level of the rest of Grandview Parkway, and often goes above other primary roads, such as Garfield Avenue. Afterall, locals consider this stretch to be the lifeline of Leelanau County. Furthermore, I didn’t change M-22 or 72 to primary roadways, as they aren’t nearly as busy as their combined traffic. It is relatively uncommon for traffic southbound on M-22 to turn west onto M-72, or eastbound traffic on 72 to turn northbound onto 22. However, if it should be changed back, i’m happy to do so.
