In 1955, US 98 replaced the MS 24 designation from US 51 in McComb to east of McLain; as a result, MS 24 was split into two segments. In 1957, the paved portion of MS 24 west of Woodville was extended further to the west. The eastern segment of MS 24 between McLain and the Alabama border was redesignated as MS 594 in 1958. In 1962, the highway was paved to a point east of Fort Adams. Paving was completed on the remainder of MS 24 leading to Fort Adams in 1964. In 1967, the eastern terminus of MS 24 was truncated to its current location at the interchange with I-55; US 98 replaced the route between there and US 51. Since then, MS 24 has remained on the same alignment.
