As I asked in the original thread: are they officially overlapped (i.e. both have legal definitions that include the same stretch), or is there just signage for both for the sake of continuity? I have a feeling the latter is way more common in these situations, meaning the supposed overlap officially has only one name.
For this particular case, I'm not sure what it is officially nor how to find out.
However, based on the mast arm signage (which has no mention of Stone Rd in the direction of the overlap), I suspect it's officially known as only Tobey Rd.

Interesting resource, thanks. Found what was I looking for on pg 187 of the
Monroe County file. Surprisingly, the overlap is "officially" Stone Rd, but the corresponding 0.09 mile segment for Tobey Rd shows an blank start point and endpoint of NY 65, so we're no closer to an answer there.
Wikipedia offers a little additional insight -
unsigned CR 62 (Tobey Rd) is split in two and does
not include the overlap in the mileage. Google Maps, for their part, has CR 62 marked on the overlap, but I don't put much stock in that. The 0.05 mile segment of Tobey Rd in the local roads listing was also throwing me, but I think it might be
this (which could be what's causing the blank start/endpoints if it's reading Tobey Rd = CR 62).
