Kentucky Route 93 (KY 93) is a 27.734-mile (44.634 km) state highway in western Kentucky.
The route is separated into two segments. The southern segment runs from Kentucky Routes 139 and 276 southeast of the unincorporated community of Lamasco to Kentucky Route 810, Kentucky Route 819, and Iuka Ferry Road northwest of Kuttawa via Lamasco, Confederate, and Eddyville. The northern segment runs from Kentucky Route 917 and Short Drive just east of Iuka to Kentucky Route 453 in rural Livingston County several miles east of Iuka via Iuka. It appears that the two segments were originally or meant to be connected, as both segments are just a few miles apart. It appears that they were to connect at the Cumberland River, at which the northern segment ends on the western bank and a rural road, likely what was or is to be part of KY 93, ends on the east bank.
KY 93 previously ran from the Tennessee State line in Trigg County to Fredonia via Cadiz, Eddyville and Kuttawa.[2] KY 93 north of Eddyville is now US 641, while the highway from the Lyon-Caldwell-Trigg County tripoint southward is now signed as KY 139.
KY 93 was reassigned to US 62's old alignment west of Kuttawa to Iuka via the now-discontinued ferry service when US 62 was reallocated to a new alignment providing a more-direct route to Paducah in the mid-1950s.[3]
