U.S. Route 89 in the U.S. state of Utah is a north-south United States Highway spanning more than 502 miles (807.891 km) through the central part of the state, making it the longest road in 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.

U.S. Route 89A is a 91.74-mile (147.64 km) north–south auxiliary U.S. highway in southwestern Kane County, Utah and northeastern Coconino County, Arizona in the southwestern United States. The highway is an old routing of U.S. Route 89 from Bitter Springs, Arizona to Kanab, Utah. The state of Arizona has designated this highway the Fredonia-Vermilion Cliffs Scenic Road. The highway is used to access the North Rim of Grand Canyon National Park and is known for the Navajo Bridge. Until 2008, the Utah portion was signed State Route 11. The route provides the only direct road connection between the Arizona Strip and the rest of Arizona.
