TDOT designations
Most of State Route 6 is a primary highway; however, between SR 397 in Frankiln and SR 254 right past the Davidson County line to SR 155 are all the areas where State Route 6 is secondary. There is ambiguity between the two Davidson County Functional Classification Maps (19b & 19a) and the TDOT Traffic Map information is not consistent designations of the Primary and Secondary route in Davidson County.
