Based on the current agreement on the highway classification, "routes"
should maintain their type along their length. Now the road types are
often assigned after TIGER classification so different road's pieces
have different types [1]. Instead, the same type should be used along
the whole road (trunk for WI 57 case, I believe) and other tags should
be used to refine road properties, like number of lanes, smoothness,
maxspeed etc.
