Kentucky Route 164 (KY 164) is a 36.247adj=midNaNadj=mid state highway in western Kentucky.
KY 164 begins its run on Linton Road from U.S. Route 68 (US 68, co-signed with KY 80) and Old Canton Road Connector in the western Trigg County community of Canton. It parallels the eastern shores of Lake Barkley while traversing the small communities of Donaldson and Linton. It turns eastward to cross KY 139 and becomes Roaring Springs Road afterwards.
After traversing the town of Roaring Springs, and also paralleling the northwestern boundary of the Fort Campbell Military Reservation, KY 164 turns northeastward before entering Christian County.
KY 164, locally known as Newstead Road, ends at the junction with KY 272 west of Hopkinsville.
KY 164 originally ran from the Tennessee State line northeast of the now-extinct town of Model, and entered the community of Linton via a ferry crossing of the Cumberland River, and then joined its present-day alignment from Linton to near Hopkinsville.[2] Ferry service was discontinued after the river was impounded to become Lake Barkley in the early 1960s, and KY 164 was rerouted onto Linton Road to Canton. The road west of the ferry crossing site is now Forest Road 204 within the Land Between the Lakes National Recreation Area.
