I've been marking all members in a relation as a role "member" not forward/backward as we don't have official designations such as east/west/north/south like they do on US interstates.
I'm not saying I'm right but it is less work :) You have ref=NHA20 for NHA20 in SA, but I'm not sure what to do here, because the road is tagged as A20 in a NH shield, just so South Australia can be different I guess :) I think I'd just tag it as ref=20, network=A and then we can add a rule to show NH shields for these routes for addr:state=South Australia _______________________________________________ Talk-au mailing list Talk-au@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-au
