Route description[edit]

Marion County[edit]

SR 108 begins as a primary highway in Marion County at an intersection with SR 28 in Whitwell. It travels to the north as Main Street into downtown and then turns northeast as Cumberland Drive and leaves Whitwell. It then ascends to the top of the Cumberland Plateau and passes through primarily rural terrain, where it passes through Griffith Creek, until it reaches Grundy County.[2]

Grundy County[edit]

SR 108 continues north through rural terrain until it enters the town of Palmer and passes through its downtown area. It then comes to an intersection with SR 399, where it enters Gruetli-Laager.

SR 108 passes through the city for approximately 6 miles (9.7 km), Before entering Coalmont, where it has an intersection with SR 56 for the first time. Approximately 1 mile (1.6 km) past the SR 56 intersection, it leaves Coalmont and enters rural terrain again, where it comes to an intersection and becomes concurrent with SR 50 and turns back north on SR 50 east. After approximately three miles (4.8 km) of mostly wooded terrain, the highway enters Altamont, where they continue into downtown and come to a second intersection with SR 56, where SR 50 ends and SR 108 becomes concurrent with SR 56 for a mere 184 feet (56 m), where it becomes a secondary highway, before splitting from SR 56 and turning west, leaving Altamont. Just after leaving Altamont, it turns back north and continues on a northerly track through a mix of hills and farmland until it crosses into Warren County.[3]

SR 108 and SR 127 stay merged for eight miles (13 km), where they pass through downtown before leaving Viola and having an intersection with SR 287, to a y-intersection where SR 108 turns north and SR 127 continues northeast. SR 108 then enters McMinnville city and continues north until it intersects SR 55 Bus. It then travels concurrently with SR 55 Bus. and goes northeast through a couple of neighborhoods before crossing the Barren Fork River and enter downtown, where SR 108 meets its northern terminus at SR 56 and SR 380.[4]
