I just found a weird overlap between this (a trace?) and the threeseparatesegments from the tiger data that forms NY 17. There also seems to be some oddball overlapping in the area of the NY 17/US 6/I-87 interchange...
I find things like this in various places. Since the tags only refer to Potlatch and have almost no other information, it was probably drawn by hand before the Tiger import happened.
