Ambiguous cycleway in Middle Tennessee

Nashville east, near Lebanon (SE of it) there is a mysterious bit of asserted cycleway infrastructure:

osm.org/way/1443369128

Which, if anybody were to cycle here and survey “what connects Old Trammel Road to Trammel Lane?” (for a cyclist, bicycle=*, highway=cycleway?…) helps build United States Bicycle Route 80 through Tennessee. (More accurately, that is; it’s built to alpha-1 now).

It might be highway=cycleway but this way is now tagged highway=service + bicycle=designated. On-the-ground eyes and tagging skills seem needed or helpful here. I usually don’t ask; thanks in advance if anyone bikes there! It could use a surface=* tag which might have value gravel, dirt or paved – unknown.

It’s not a critical missing link as it is tagged now, something like 187 meters.

Is it a gravel cul-de-sac connecting to Old Trammel Road? (Not critical, just how it’s tagged now)

Thanks again. People planning a long ride across this stretch, it helps knowing what it is.
