Expect a turn-heavy local drive that keeps you engaged behind the wheel. Unlike a monotonous interstate slog, this route features zero highway miles, meaning you will navigate surface streets for the entire 105.7-mile duration.

Most of the miles stay on highways, which makes pacing and fuel planning easier than turn-by-turn city driving.

Trip Plan
