KY 88 traverses the Western Kentucky Parkway via an overpass without access.

It passes through the communities of Grayson Springs, Peonia, and Wax.

It runs concurrently with US 31W in downtown Munfordville and on the bridge over the Green River.

KY 88 splits from US 31W near the Hart County High School to continue east to cross US 31E at Hardyville.

It crosses the Green River a second time before ending just north of Greensburg along KY 61.
