U.S. Route 189 is a spur of U.S. Route 89. It currently runs for 322 miles (518 km) from Provo, Utah at Interstate 15 to Jackson, Wyoming. The highway was not part of the original 1926 U.S. Highway system. The highway was created in the 1930s, absorbing former U.S. Route 530 and a portion of U.S. Route 30S. The portion through Provo Canyon (between Provo and Heber City, Utah) has been designated the Provo Canyon Scenic Byway by the state of Utah. Route description Utah US-189 begins in Provo where it is known as University Avenue, referring to Brigham Young University. The highway then winds up Provo Canyon passing by Deer Creek Reservoir and paralleling the route of the Heber Creeper (now known as the Heber Valley Railroad). The portion in Provo Canyon is designated the Provo Canyon Scenic Byway by the state legislature. The highway exits Provo Canyon near Heber City, Utah. At Heber City US-189 meets U.S. Route 40 and is co-signed with Route 40 all the way to its junction with I-80. Prior to the construction of the Jordanelle Reservoir, the highway continued north concurrent with the former alignment of US-40 that is now under water. US-40 and 189 separated at Hailstone, also now under the lake. US-189 emerged from the lake shore along the route now signed State Route 32. SR-32 and former US-189 join I-80 in Wanship. Prior to the completion of Interstate 80 in eastern Utah US-189 formed the main streets of Coalville and other communities now bypassed by I-80. The Utah section of US-189 is defined in Utah Code Annotated § 72-4-124(2). The Utah Code does not contain the concurrent alignment along US-40 and I-80, but the concurrent portion is included in Utah Department of Transportation maps of the area. Wyoming US 189 enters Wyoming from the west co-routed with Interstate 80. The routes separate east of Evanston, at exit 18, where US 189 proceeds north through the town of Kemmerer, home of the JC Penney Mother Store which is located along the route. US 189 continues north, eventually following the western shore of Fontenelle Reservoir and passing Names Hill before entering La Barge, passing what is left of the Moondance Diner, which was moved to the town from New York City in 2007, and is famous from many movies and television shows. The route then continues north along the Green River towards
