Drive Character
Expect a turn-heavy local drive that demands your full attention rather than a monotonous interstate cruise. Since the route features 0% highway share, you will navigate local roads for the entire 121.7-mile duration. This lack of highway driving means your speed will likely remain consistent but moderate as you work through the various turns along the path.

Prepare for a road character that prioritizes local navigation over high-speed transit.
Most of the miles stay on highways, which makes pacing and fuel planning easier than turn-by-turn city driving.
There are about 23 navigation steps in the underlying route data, so the final approach matters more than the middle miles.
