Also in 1930, North Carolina tried to get US 421 extended west from Boone to Johnson City. In Tennessee this would've followed TN 91 from Elizabethton to Johnson City. North Carolina then thought US 421 should be renumbered as US 44or US 72, as they apparently didn't own any maps to consult).
Between 1941-51, TN 91 was extended west to the rerouted US 11E (now TN 400) at Wautauga St. Also changed to use Market-Division-Main.
Between 1952-55, TN 91 was extended west to the rerouted US 11E-411 at John Exum Pkwy. Also in this timeframe, TN 91 was given one-way splits in Johnson City. EB used Watauga St to Main. WB used Division St to Market.
In the 1950s, TN 91 was put on one way splits in Elizabethton. EB used the original routing on Elk Ave and WB used N. Sycamore and E St.
About 1961, US 321 was added to TN 91 from Johnson City to Elizabethton.
In 1965, TN 91 was removed from Broad St east out of Elizabethton and placed on its current routing (US 19E hadn't been moved yet though).
Between 1965-71, TN 91 was given its more direct routing through Elizabethton via Broad St. East of the Doe River TN 91 had used Elk Ave to Main St to Broad St.

About 2009, TN 91 was given a bypass of Mountain City as mostly new construction. This left behind a bit of US 421, an extended TN 418 on Main St and Church St north out of town.
