This NYDOT docs on local roads for Delaware County makes it pretty clear. Roses Brooks ends at Narrows Notch Rd but then Roxbury Mountain Rd begins at Narrows Notch Rd, meaning the tree must meet at an intersection. Furthermore, the addresses also make it clear that Narrows Notch must begin near that intersection.

I am correcting it now.
