Infrastructure safety: I-75 through Tennessee has high traffic volume; speed limits 70 mph. I-65 in southern Indiana is undergoing widening—watch for narrow lanes and construction debris. Road quality on I-74 in Illinois is excellent, but prone to crosswinds on elevated sections.

• Rest zones: Tennessee rest areas every 30 miles (clinics present). Indiana has travel plazas with food courts and dog runs.
• Fatigue management: plan stops every 2 hours. Ideal pause points: Corbin, KY (Exit 15) for a break at the World Chicken Festival ground; Lafayette, IN (Exit 168) for the Columbian Park Zoo.

Pet-friendly framework: Most rest stops allow leashed pets. Chain hotels (La Quinta, Motel 6) are pet-friendly with no fees. For off-leash time, use the dog park at Eagle Creek Park in Indianapolis (just off I-65).

Family and child suitability: Kenlake State Park (Hardin, KY) has a splash pad and playground. The Holiday World theme park in Santa Claus, IN (Exit 63 off I-64) is 90 minutes from route but perfect for kids.

Hidden off-route spots: The Whiskey Trail in Kentucky (Woodford Reserve, Buffalo Trace) is a 30-minute detour off I-64 near Frankfort. In Indiana, the West Baden Springs Hotel (French Lick) is a historic dome resort with mineral springs—a 40-minute loop off I-65 (Exit 76).
