Are we considering the traffic data report the end-all/be-all? I, for one, find the NY 314 truncation doubtful, given the ferry is an interstate crossing.
(EDIT) As a follow up, I checked the 2014 Inventory Listings for the counties involved (
accessible here). The Inventory Listings show all four touring routes mentioned as still in-place as before, albeit now county maintained (and city of Watertown maintained for a stretch of NY 12E). This may explain why they're not on the traffic data report.
I think we should wait and verify whether these route segments are unsigned before we take them off TM. Though I believe I've seen a photo showing 374 signage changed to a county route north of 11.
