State Route 30 (SR-30) is a state highway in the U.S. state of Utah. It is the only highway signed as a Utah state route (with the beehive shaped route marker) to traverse the entire width of the state. The legal definition of the highway has 3 separate segments. With implied connections via Interstate 84 and U.S. Route 89, the highway is drivable as a continuous route from Nevada to Wyoming. The western segment is a historic corridor paralleling the pre-Lucin Cutoff routing of the First transcontinental railroad. A portion of the eastern segment has been designated the Bear Lake Scenic Byway as part of the Utah Scenic Byways program. The route was created in 1966 by combining several state highways into a single designation.
