Well, I do not get your problem, as bridge/tunnel always need a layer tag and you already have to cut the ways to tag the bridge/tunnel, why not simply add the layer to the bridge/tunnel and leave everything else untouched ? Using layer tags on long ways is discouraged as you often only need it on a small part and it makes it more difficult as you always have to check the layer tag of these long ways before adding a new bridge/tunnel with appropriate layer value. cu fly _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
