Don't do this!  OSM convention for state highways is to use the state
abbreviation, not "SH" or "SR".  This is done to disambiguate refs and make
it easier for renderers that are still using this obsolete tagging
convention rather than using route relations.  Don't tag for the renderer,
but don't break it intentionally, either!
