[Talk-us] Tagging of county roads

Exactly what tagging are people using for county roads in the US? I tried 
to answer this by reading the wiki, but it focuses only on the highway=* 
categorization, and not on any actual examples. I also tried searching with 
nominatim*, but came up with roads entitled "County Highway *" and "County 
Road *" without any ref tags.

It seems that the county road number should go in the ref tag, and this is 
what I've seen in some cases, but where should the county and state go? 
I've used is_in:county and is_in:state_code in the past for other things 
(like bridges and mileposts), but people don't seem to like these, and 
they're not exactly right - I'm not trying to say where the roads are, just 
complete the reference tag with what's on the signage.

Currently, for example, I'd tag Santiago Canyon Road in Orange County, CA, as:

highway=secondary
ref=S18
is_in:county=Orange
is_in:state_code=CA

Does it make sense to add a network=US:CA:Orange tag (like the relation) 
instead of the is_in:* tags?


If/when I create a relation for it, the relation would be tagged:
type=route
route=road
network=US:CA:Orange
ref=S18



*BTW, Nominatim doesn't seem to show the state in it's search results, 
though I think it's showing city, county, country. Can this be fixed? It 
makes it kind of hard to know what you're looking at if you're not familiar 
with the county names in the area being searched.
