State Route 330 (SR 330) is a state highway in East Tennessee, most of which is also known as Frost Bottom Road, that runs southwest to northeast from Oliver Springs to the junction with SR 116 at Laurel Grove.

It goes south as Winter Gap Road before turning east (left) on Main Street.

It then comes to a 4-way stop, where SR 330 turns east (left) onto E Spring Street, where it leaves downtown and begins passing through neighborhoods.

It then has another railroad crossing before leaving Oliver Springs and becoming slightly curvy for a short distance before crossing a bridge and coming to an intersection with Dutch Valley Road, where SR 330 turns northeast (left) onto Frost Bottom Road.

It continues northeast through a narrow valley through rural areas as an improved 2-lane highway before entering Laurel Grove and coming to an end at an intersection with SR 116.
