My approach (and I don't know if you'll agree with this) is to consider "Pacific Highway" something independent of I-5 or Oregon 99. Pacific Highway is more like its own designation for a highway, and ways which belong to both I-5 and Pacific Highway (or Oregon 99 and Pacific Highway) are treated like any other co-signed highways: just by adding the affected ways to the relations for each highway. I'm not sure what you meant by "Why redundantly tag the name seperately from the relation, when name= works so well for that already?" but doing it this way would reduce redundancy by not having several ways with "name=Pacific Highway" (and make it trival to change toll fees (if any) affecting the whole highway, link to http://en.wikipedia.org/wiki/Pacific_Highway_(U.S.) with the wikipedia:en tag, potentially add a symbol, etc). It also allows you to expand the highway to streets if needed without replacing the name of the street. (this case may not be needed for the Pacific Highway, but like I've said in another email, it is needed for the Skokie Highway in Illinois). -- Joseph Booker
