State Route 184 (abbreviated SR 184) is a 12.92miles long highway in West Tennessee, running between the cities of Troy and Union City.
SR 184 begins at Troy as a rural two-lane secondary highway at an intersection with SR 21 and continues parallel to the US 51/SR 3 expressway for its first 8.5miles. Entering Union City, SR 184 has a diamond interchange with the SR 690 (Future I-69) freeway. Within Union City, SR 184 is a 5-lane undivided highway and follows E. Reelfoot Avenue for approximately 1.75miles as a hidden concurrency with US 45W. SR 184 turns northerly at Miles Street for 0.86miles and then turns northwesterly along Nailing Drive before terminating at the SR 22 freeway. At this point, SR 184 changes to SR 214, which continues north along the Kenn-Tenn Highway. SR 184 is unsigned from its junction with US 51 to its northern terminus at SR 22.
SR 184 from Troy, Tennessee to Union City, Tennessee represents the old two-lane alignment of US 51 & SR 3.
