State Route 75 (SR 75) is state highway in Tennessee in the northeastern portion of the state. The highway begins at US 11E and US 321 in Limestone and ends at Tennessee State Route 126 in Blountville.[1]


A widening project has been taking place on SR 75 to provide a four-lane highway from Interstate 26 in Gray to the Tri-Cities Regional Airport in Blountville. On November 1, 2013 TDOT opened all four lanes of traffic, but much work still needs to be done.[2]
