Drive Character
Expect a turn-heavy local drive rather than a monotonous interstate sprint, as only 15% of this route takes place on major highways. You will spend much of your time navigating local roads, which keeps the experience engaging behind the wheel. The longest uninterrupted stretch you will encounter is a 19.1-mile segment on the Blue Star Memorial Highway. As you transition between the various highways, the road character shifts from regional corridors to local pavement. Be prepared to stay alert, as the winding nature of these roads demands more attention than a standard high-speed commute.
This route has more turning and local-road decision points than a simple highway run.
There are about 25 navigation steps in the underlying route data, so the final approach matters more than the middle miles.
Blue Star Memorial Highway is the longest continuous segment at about 19.1 miles.
