The route begins in Fairview at the intersection of US-89 and SR-31 following SR-31 eastward and immediately connects with the north end of SR-231. As it exits the city, it turns northeast to follow Cottonwood Creek towards and into Fairview Canyon, about 2 miles (3.2 km) from the beginning of the route. It follows the canyon for another 6–7 miles, entering the Manti-La Sal National Forest, until it climbs out of the top end of the canyon at about 8,800 feet (2,700 m) altitude. From this point, the byway splits in two.
The south branch continues to follow SR-31, climbing up to over 9,600 feet (2,900 m) elevation before dropping down to the east-southeast as it passes Huntington Reservoir, Cleveland Reservoir, and turning to the northeast towards Electric Lake. At this point, the route turns to the southeast, following Huntington Canyon and Huntington Creek downwards, eventually exiting the national forest and the canyon and ending in the city of Huntington, a mile southwest of Huntington State Park.
The North branch turns onto SR-264, which travels eastward towards the north end of Electric Lake, where it turns north to go up Upper Huntington Canyon. After about 3 miles (4.8 km), the route turns east again and climbs out of the Upper Huntington Canyon, and crosses over to Eccles Canyon, following Eccles Creek down. After about 6 miles (9.7 km), the canyon and the route turn back to the north again, passing through the town of Scofield, and passing by Scofield Reservoir and state park. It continues on past the north end of the reservoir for a few more miles before turning to the east yet again, ending northwest of Price Canyon near Colton.
