The entire route consists of well-maintained interstates, but watch for construction zones near Knoxville (I-40/I-75 split) and Cincinnati (I-75/I-74 merge). Winter driving from December to February may bring snow and ice north of Lexington—carry chains or all-weather tires. Summer thunderstorms can reduce visibility; slow down during downpours.
