Its southern terminus is in Almaville, an unincorporated community in the western part of the county, at SR 96.

The southern half of SR 102 is called Almaville Road and has an interchange with I-840.

The two-lane road travels north through rural, undeveloped land until reaching the rapidly growing residential and warehouse areas just outside Smyrna and expanding to four lanes.

After an interchange with I-24, SR 102 becomes Lee Victory Parkway, named after a prominent local politician.

The highway's northern terminus is at Jefferson Pike; northbound traffic on SR 102 continues westbound on Sam Ridley Parkway/SR 266 on its way back towards I-24.
