context_page_description: State Route 20 is a state highway in southern Utah, running 20.492 miles in Iron and Garfield Counties, without directly serving or connecting any cities. It serves as a truck connection between I-15 and US-89 and an access to Bryce Canyon National Park. It may also be used to travel between Salt Lake City and Phoenix, Arizona. The highway follows the route of the Old Spanish Trail.
context_section_description: SR-20 begins at I-15, Exit 95, 14 miles (23 km) north of Paragonah, and heads east and southeast through a pass between the Markagunt Plateau and the Tushar Mountains.  It ends at an intersection with US-89 at Bear Valley Junction.  Trucks are routed from I-15 and US-89 onto SR-20 in preference to SR-9 and SR-14 to avoid steep grades and switchbacks required to cross the Markagunt Plateau. Because of this, SR-20 is included in the National Highway System.  SR-20 itself is a difficult route, featuring 7% grades on the approaches to the 7,910-foot (2,410 m) summit, and oversize vehicles are required to have a pilot escort.
