You will start your trip on FM 1069 North before transitioning onto Highway 188 and eventually picking up I-37 to complete the journey.

Most of the miles stay on highways, which makes pacing and fuel planning easier than turn-by-turn city driving.
There are about 12 navigation steps in the underlying route data, so the final approach matters more than the middle miles.
I 37 is the longest continuous segment at about 110 miles.
