Hi Louis, I believe the proper way to tag this is by using the semi-colon to seperate the possible values. Eg 'ref=19A;172'. I think you should tag it 'highway=primary' and not 'highway=primary;secondary'. At least in Ireland, there are a few national routes that have a motorway section (eg N4 is the main road and part of it is a motorway, the M4). The motorway section would be 'highway=motorway' Ref: http://wiki.openstreetmap.org/index.php/Faq#What_shall_I_do_for_roads_that_have_multiple_values_for_a_tag.3F Rory _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
