Can you explain why you tagged a city (or town) boundary line as a road in this changeset? I do not see a road lining the city boundary line in the aerial imagery. Are you trying to map for the renderer? If so, then please note that it is not good practice on OSM. Don't incorrectly tag valid map data or add incorrect data to OSM just because you want it to show up in the map renderer of your choice or to make it look prettier. Map or tag things as they are on the ground. See https://wiki.openstreetmap.org/wiki/Tagging_for_the_renderer
