SR 30 is routed along a two-lane roadway for its entire length. It serves as a connector route between Clayton, the county seat of Barbour County, and Eufaula, the county’s largest city and primary center of retail. Between the two cities, the highway travels through rural areas with no cities or towns. After intersecting two minor state routes at Clayton, the highway does not intersect any other state routes or U.S. highways until its terminus south of Eufaula.

The entire route is in Barbour County.
