State Route 9 (SR-9) is a 57.075-mile-long (91.853 km) state highway in southern Utah, serving Zion National Park. It starts at the western terminus at exit 16 on Interstate 15 (I-15), passing through Zion National Park, and ending at the eastern junction with U.S. Route 89 (US-89). The entire length of the highway has been designated the Zion Park Scenic Byway. There is a fee to travel through Zion National Park, but the Zion-Mt. Carmel Highway is open to private vehicles year-round. A separate fee is required for vehicles 7'10" wide and/or 11'4" tall or larger. This fee pays for a park employee to stop traffic from the other side of the Zion - Mt. Carmel Tunnel to allow the larger vehicles to pass through. There is a smaller tunnel in Zion National Park that does not require an escort. Commercial vehicles are prohibited from using SR-9 and are directed to use SR-20 instead.
The entire route, including the connection through Zion National Park, has been listed as part of the National Highway System.
