The route connects SR-18 to Dixie Downs Road via Sunset Boulevard in a span of 1.3 miles (2.09 km). Prior to 1999, SR-8 extended north to Snow Canyon State Park. However, the route was truncated to its current point that year.
State Route 32 (SR-32) is a state highway in Wasatch and Summit Counties in the U.S. state of Utah.

Interstate 70 (I-70) is a mainline route of the Interstate Highway System in the United States connecting Utah and Maryland. The Utah section runs east–west for approximately 232 miles (373 km) across the central part of the state. Richfield is the largest Utah city served by the freeway, which does not serve or connect any urban areas in the state. The freeway was built as part of a system of highways connecting Los Angeles and the northeastern United States. I-70 was the second attempt to connect southern California to the east coast of the United States via central Utah, the first being a failed attempt to construct a transcontinental railroad. Parts of that effort were re-used in the laying out of the route of I-70.
State Route 161 (SR-161) is a 3.084-mile (4.963 km) long state highway, designated as a rural major connector, completely within Millard County in central Utah.

Between Provo and Brigham City, US-89 serves as a local road, paralleling Interstate 15, but the portions from Arizona north to Provo and Brigham City northeast to Wyoming serve separate corridors. The former provides access to several national parks and Arizona, and the latter connects I-15 with Logan, the state's only Metropolitan Statistical Area not on the Interstate.

It was formed in 1965 coinciding with the construction of I-15 through the area. At the time of formation, the route at the eastern terminus was legislatively designated SR-106, though it was signed as US-89 and US-91.
