Good rule. Ought to be the standard.

But besides that, my general feeling is that primary streets and a minor highways fulfill the same roles, only one has a highway number (US or state) and the other one doesn't (or it's a county highway). Rare exceptions apply, of course.

There's lots of 2 to 3 lane and some 4 lane wide roads here that aren't numbered highways, and if they weren't urban no one would have qualms about saying they were highways. I've made them Primary as I come across them, but the only preference they seem to be getting is on account of their generally higher average speeds.
WeeeZer14 wrote:What is the point, well it may be that the original intent was display only. Just like my thought for Service Roads. Priority is part of what we are trying to hash out in the discussion of NJ road types. Right now I am thinking that primary street should be a tier below Minor Highway. It is something that is important/high volume, but calling it a highway would be very generous.
I guess this touches on some of the difference between a highway (a physical structure) and a route (a logical designation). Sometimes they play nice together, other times they bash heads.
