Thank you for converting the artwork node into a ruins node. The feature is inherently a ruined bridge support.

However, I'd like to see the artwork tags preserved, either on this node or another node. 

Maybe the ruins can be converted into an area, and the artwork can be added back as a node on the area? When I surveyed the bridge support, it was rectangular, wider on the north/south sides than the east/west sides. The graffiti was on on the longer, southern face.
