Yup - that is problematic. I think, when I marked Orange County S18 last
year, I didn't see any other county road tagging to go by.
http://www.cahighways.org/county.html shows that there are some
occurrences of this. I apparently expected to break them at the county
lines, I guess, so as to agree with signage. That is, Orange County S99
would be a different route than San Diego S99.
network="US:CA:Orange;US:CA:San Diego" on the relation seems workable.
They're really not different routes. They could be split at county
lines, like U.S. Highways are split at state lines, but the network
should be the same.
It's almost like they defined super-groups of counties identified by
those letters. I'll have to crunch that table to see if that's the case
so we could have network=US:CA:S + ref="CR S18". Maybe add an
is_in:county tag to the individual segments to avoid losing that
important info.
How about simply network=US:CA:CR?
