US 51/
SR 3 south of
Henning. It then proceeds northeastward and enters the Henning city limits and in downtown Henning SR 209 has a brief
concurrency with
SR 87. It then continues northward and enters
Ripley city limits. It has a half-interchange with
SR 19 and enters downtown Ripley and serves as the southern terminus for
