Infrastructure Safety & Road Quality

The route is well-served by highway patrol, especially on I-15. In remote stretches (e.g., US-89 between Kanab and Mt. Carmel Junction), cell service is spotty. Download offline maps. Speed limits: 70 mph on most highways, but 55-65 mph in construction zones. Large animal collisions (deer, cows) occur near agricultural areas; dusk and dawn are highest risk.

• Emergency services: Call 911; CHP coverage on I-5 and I-15, Utah Highway Patrol on US-89.
