All of SR 324 is nestled within the confines of Clinton Township in the southeastern portion of Vinton County.

The highway starts out traversing heavily wooded terrain, but soon transitions into a more open landscape.

Further along, the terrain starts to vary more, with a blend of forest and field appearing for much of the remainder of the length of SR 324.

It turns north into the hamlet of Dundas, and passes a number of homes just prior to bending to the northwest, after which it crosses a set of railroad tracks and arrives at its endpoint at its junction with SR 93.

For the duration of its history, this state highway has maintained the same routing within the southeastern quadrant of Vinton County.
