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.

Previously the route had entered northern Utah, ending at US-91 in Brigham City, but with the completion of I-15 it was truncated to Yellowstone National Park and re-extended on a completely different alignment. In addition to a large portion of US-163, this extension absorbed several state routes: SR-33, most of SR-44, and SR-260.

Although it is only about 40 miles (64 km) longer than US-50, it serves more populated areas and, in fact, follows what had been US-50's routing until it was moved to follow Interstate 70 (I-70) in 1976. In 2009, the Utah State Legislature named part of the route the "Mike Dmitrich Highway", named after the Utah state senator, which generated controversy, as the state of Utah had previously joined with all the other states through which US-6 passes in naming all of US-6 the Grand Army of the Republic Highway.
