I have tended to use tertiary for roads that were A or B Roads that have been By-passed. ie Its still a perfectly usable main road but the road number has been taken by the by-pass. After all they have to build there passes.... (Quote: Hitch Hikers Guide) I also suspect some mistakes. Oh and Some unclassified Roads that actually go somewhere, That is used by people all the time but has not got a number (or someone has forgotten what it is) I also know Unclassified Roads round me that are wider than some of the A roads. The military like building them, that and industry. Peter. _______________________________________________ Talk-GB mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk-gb
