U.S. Route 189
U.S. Numbered Highway Utah and Wyoming in the United States
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.

Why this record matters

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 26, 2026. The linked authority identifier is Q2507252. Authority coordinates are 40.207, -111.661. 1 of 3 selected statements include explicit references; 2 carry qualifiers and 0 use preferred rank. The first chronological checks are 1926.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
