State Route 215 (SR 215) is an unsigned, east–west, state highway entirely within the city limits of South Fulton, Tennessee, although the direction is more northwest to southeast as it curves around the southwest part of the city.

The northwestern portion is a four-lane divided highway and the southeastern portion is a four lane undivided highway with a center left turn lane.

Starting from its intersection at US 45E/SR 43, SR 215 (along with US 45E) travels in a westerly direction and then curves toward the north.

At this intersection, SR 215 continues north for about 1300 feet until the Kentucky state line.

The way the interchange is currently configured would more than likely have to be altered in order to eliminate some left hand turns.
