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.{{cite web 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).{{cite web
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 the neighboring towns of
Big Piney and
Marbleton. This area is heavily developed by the
Oil and Natural Gas industries. The route then cuts across the northern part of the
Green River Basin through the town of
Daniel and intersects with
US 191 at Daniel Junction and runs concurrently to the north. Continuing north, the road traverses increasingly mountainous terrain, entering the
Bridger-Teton National Forest and passing through the small community of
Bondurant before descending through the narrow
Hoback River Canyon to an intersection with
US 26 and rejoining its parents route,
US 89 at Hoback Junction. ==History==
