TN 34 Spur: Appeared in 1959 as a renumbering of TN 34 along Persimmon Ridge Rd between the Jonesborough Bypass and TN 81 Main St.
It is explicitly shown on maps at least 1964-81.
The next map I have it 1986 and shows no state highway at all. it is unclear if it was renumbered as something else first in 1983 before going away.
I believe the point of this route was to connect to TN 81 which has no direct connection to the Jonesborough Bypass.
