In the U.S. state of Utah, some state highways have been specifically designated to serve state parks and state institutions. The range of numbers from State Route 281 to State Route 320 has been used for this purpose since 1969.

State Route 313 is a 22.506-mile (36.220 km) route that connects US-191 northwest of Moab with the overlook in Dead Horse Point State Park. It was created in 1975 as a replacement for SR-278, which would have connected the park to SR-279.

State Route 300 ran southwest from SR-18 in Snow Canyon State Park from 1972 until 1996, when it became part of SR-8. The former SR-300, about 3.74 miles (6.02 km) in length, was dropped from the state highway system in 1999 to allow the Utah Division of Parks and Recreation to carry out their resource management plan.
