Previous TN 75's:


TN 75 #1: An original state highway which in 1924 ran from TN 11 (now US 41) Springfield northeast to the Kentucky State Line at Mitchell.
In 1925 or 1926, TN 75 north was truncated to and replaced by TN 79 at Reubensville. Today TN 75's routing from Reubensville to Mitchell is US 31W except: lengthy visible abandoned segment to the west from Old TN 52 WB to north of Byrum Chapel Rd; Old Hwy 31W in the Summers Branch area
In 1927 or 1928, TN 75 was renumbered as TN 49 from Springfield to Orlinda and TN 52 from Orlina to Reubensville. Today this is still largely TN 49 and TN 52 except a couple abandoned TN 52 alignments near Handleyton and East Old highway 52 in Reubensville.

TN 75 #2: Appeared in 1927 or 1928 as new routing, running from US 25-70 Newport south through Cosby to the NOrth Carolina line near the Sevier-Cocke line.
In 1931 or 1932, maps started showing TN 32 cutting east from Cosby to enter North Carolina at Mount Serling. Before then, TN 75 likely was using Stone Brook Dr, a bit of US 321, Connie Town Rd and Laurel Springs Rd. Old Topos show a road continuing along today's Maddon Bald Trail to about 2 miles short of the NC line, so it is possible the southern end of TN 75 was aspirational rather than driveable road.
In 1939 or 1940, TN 75 became part of TN 32. It is still TN 32 except TN 75 used Cosby Bridge Rd; Old Hwy 32; Armory Rd; Cosby Cutoff Rd; Old Cosby Highway in Newport. East from Cosby, TN 32 is EXACTLY as it was during TN 75's day. WAY more curves than Tail of the Dragon.
