This sounds like a great use for the network tag to me.  There are basically
4 highway networks in this country:  Interstate, US, State, and County.  I
know that technically each state and county has it's own separate network,
but most renderers are just going to display generic shields for state &
county.  For those who do want to render different shields for each state
and/or county routes why not use sub tags as we commonly do for many other
osm features:

For Michigan route 12:
ref=12
network=state
state=michigan

For Bennington County route 16 in Vermont:
ref=16
network=county
state=vermont
county=bennington
