Kentucky Route 300 (KY 300) is a 16.6adj=midNaNadj=mid state highway in the U.S. state of Kentucky. The highway connects mostly rural areas of Boyle and Lincoln counties with Parksville, Junction City, and Stanford.
KY 300 begins at an intersection with KY 34/KY 1822 (Lebanon Road) in Parksville, within Boyle County; however, only KY 34 is signed at this intersection. It travels to the east-southeast and leaves Parksville. It travels just north of Wilsonville. It curves to the east-northeast and enters Alum Springs, where it intersects the northern terminus of KY 3365 (Hogue Hollow Road). The highway curves to the southeast and begins a concurrency with KY 37 (Stewarts Lane). Almost immediately, they enter Junction City. They split, and KY 300 crosses over some railroad tracks of Norfolk Southern Railway. KY 300 then intersects U.S. Route 127 (US 127). It intersects the western terminus of KY 1273 (Hustonville Road). It turns right onto Hustonville Road, and travels to the south-southwest. At the intersection with the eastern terminus of York Lane and the western terminus of Short Acres Road, the highway leaves the city limits of Junction City. The highway then enters Lincoln County.
KY 300 turns left onto Knob Lick Road and resumes its trek to the southeast and crosses over Knoblick Creek. It begins a curve to the south-southwest and crosses over the creek again. Then, the highway curves back to the southeast and crosses over Hanging Fork Creek. On the southeastern edge of Stanford, it intersects KY 78 (Hustonville Road). The two highways travel concurrently to the east and travel through Buffalo Springs Cemetery. They curve to the southeast and then back to the northeast. When they cross over St. Asaph Creek, they enter Stanford proper. They curve to the east-northeast and intersect the eastern terminus of KY 2319 (Helm Street). Almost immediately, they split. KY 300 travels to the north-northwest and meets its eastern terminus, an intersection with US 150 (Wilderness Road).
