The quadrants in counties like Kosciusko give away the fact that these 
aren't route numbers: in any given county, (East) 500 North is distinct 
from and perpendicular to (North) 500 East.

I think it would be reasonable to treat Elkhart County's road numbers as 
route numbers, given that the numbering continues along the route 
despite the name change. The routes just happen to coincide with the grid.

Some northwestern Ohio counties blend the two approaches. The grid 
concept is very strong here: a couple counties denote off-grid roads 
with decimal numbers to the tenths place. Williams County even goes as 
far as to post signs along the Michigan-Ohio state line indicating 
County Road T, even though the right of way lies entirely in Hillsdale 
County, Michigan, where it's known by a different name. [1][2] (It'd be 
akin to Tijuana posting signs pointing to Tijuana, California.) However, 
these road names do not continue within villages, which are under 
village maintenance.

At the same time, the county engineer does want motorists to think of 
these roads as routes of a sort: for example, Fulton County's street 
name signs look like an oversized version of Ohio's standard county 
route shield, except with an address range at the top. [3]

Since they're shields functionally, it's fair to model them as route 
relations for shield-capable renderers. But they're still road names: 
other than the shield-like sign, there's no difference between how 
Fulton and Kosciusko counties assign the road names.
