Once the concurrency begins, MS 23 and MS 178 travel westward through the center of Tremont. MS 23 departs from MS 178 to the north less than later, ending the concurrency. It travels northeastward into the forest, and soon leaves the corporate limits. At Cotton Gin Road, MS 23 turns north, crosses Mountain Creek and intersects Mt. Gilead Road and Hartsell Road in the center of Bounds Crossroads. The route intersects the eastern terminus of MS 76 and later parallels that divided highway. MS 23 shifts slightly north past Pineville Road, and it ends at the Mississippi–Alabama state line. Past this point, County Road 3, also known as Tammy Wynette Memorial Highway, continues to Red Bay in Franklin County, Alabama.
