Two days ago, I found another possible alignment that I had never noticed before. It roughly parallels 62 for about a mile just southeast of US 65 near Bellfonte. Someone sent me a lead on a possible old bridge in the vicinity so I pulled up Google maps to trangulate.
I was looking the county road and noticed it appeared to intersect US 62 in two locations... or did at one time. It appears to have been cut-off at the east end, but the satellite photo seems to show traces of the old roadway.

The blue line shows what I suspect to be old 62. The red line shows the possibly abandoned section. My research tells me there is at least one old bridge on Brack Kimes Rd, plus a possible second one on Huzzah Rd which branches off to the north and west about a third of the way down Kimes Rd.
There is only one way to find out: I have to go there. I've been looking for an excuse to go over that way, so I guess I have one now. :)
