Route description

The southern terminus of SR 99 is located at an intersection with U.S. Route 31 (US 31) in northeast Athens. From this point, the highway travels concurrently with Elm Street in a westerly direction through the city. As it exits the city limits, SR 99 changes routes, becoming an extension of Market Street before heading in a northwesterly trajectory towards Mount Rozell. From there, it then travels in a westerly direction before terminating at SR 207 northeast of Anderson.^[2]
