The U.S. state of Utah, the Utah Department of Transportation (UDOT) operates a system of state routes that serve all portions of the state. In official documents the state of Utah uses the term "state routes" for numbered, state maintained highways, since the legal definition of a "highway" includes any public road. UDOT signs state routes with a beehive symbol after the state's nickname of the beehive state. There are 3,658.04 miles (5,887.04 km) of state routes in Utah.
