Drive Character
Expect a hands-on driving experience as this route relies entirely on local roads rather than major highways. You will spend 0% of your time on highways, navigating instead via streets like Northeast 5th Street, East Main Street, and South Belt Line Road. The journey is defined by constant turns, meaning there is no single long, uninterrupted stretch to settle into; in fact, your longest stretch is 0 miles on Northeast 5th Street.

Be ready for a steady pace that keeps you engaged with the road rather than just watching the miles tick by.
Most of the miles stay on highways, which makes pacing and fuel planning easier than turn-by-turn city driving.
There are about 28 navigation steps in the underlying route data, so the final approach matters more than the middle miles.
