I agree. We need to map the various road classifications that already exist
to the UK-specific vocabulary of the OSM highway tag.

Can we come up with a list of classifications that are currently used?

My contribution (in order):
- Interstate (the Interstate Highway System. Roads designated with the
red-white-blue sign.)
- United States Highway (Roads designated with white/black crest signs.)
- State highway (state-specific numbered highway systems)
- County roads (highway systems maintained by the county. Not common to all
- Residential roads

What OSM tags should these roads map to?
