text: If https://www.openstreetmap.org/way/30622739 isn't an operational ferry right now then I wouldn't tag it as "route=ferry" - I'd use some sort of lifecycle tag to explain the current status (or in the case of a ferry route, perhaps not map it at all?).
  "disused:route=ferry" has 5 uses in the UK:
  http://taginfo.openstreetmap.org.uk/tags/disused%3Aroute=ferry
  Maybe that's the one to go for?  Needs someone more familiar with the area to sanity check the suggestion, though.
