Interstate 75 (I-75) runs from near Williamsburg to Covington by way of Lexington in the U.S. state of Kentucky. I-75 enters the Cumberland Plateau region from Tennessee, then descends into the Bluegrass region through the Pottsville Escarpment before crossing the Ohio River into Ohio. I-75 follows along the U.S. Route 25 corridor for the entire length of Kentucky.
Interstate 75 runs roughly parallel to U.S. Route 25 for its entire length in Kentucky. The freeway enters Kentucky south of Williamsburg, bypassing Corbin, London, Berea, and Richmond, Kentucky. It is briefly concurrent with Interstate 64 along the north and east sides of Lexington, before leaving the Lexington area northerly and bypassing Georgetown. South of Florence, Kentucky, the route becomes concurrent with Interstate 71, and the two routes remain concurrent through to Cincinnati, Ohio. On the north side of Florence, Interstate 75 intersects with the only auxiliary route it has in the state, Interstate 275, a beltway bypass of the greater Cincinnati area.
