It has two disconnected sections, one that goes from the Ohio River near Sloughs Wildlife Management Area to the Green River near Rangers Landing via Henderson, and the other that runs from KY 56 in Beech Grove west of Sebree to U.S. Route 231 (US 231) north of Hartford via Calhoun and Livermore.

KY 136 begins in northwestern Henderson County near a landing of the Ohio River opposite Mount Vernon, Indiana.

KY 136 traverses the Niagara community at its Kentucky Route 416 junction before ending its first section at Rangers Landing.

[2][3] Although ferry service was discontinued by 1968, road maps still mark KY 136 as running from Rangers Landing to Beech Grove.

[4] KY 136 also connected to Mount Vernon, Indiana, via a tolled ferry on the Ohio River,[5] which was decommissioned by the beginning of the 1950s
