U.S. Route 491 (US 491) is a north–south U.S. Highway serving the Four Corners region of the United States. It was created in 2003 as a renumbering of U.S. Route 666 (US 666). With the US 666 designation, the road was nicknamed the "Devil's Highway" because of the significance of the number 666 to many Christian denominations as the Number of the Beast. This Satanic connotation, combined with a high fatality rate along the New Mexico portion, convinced some people the highway was cursed. The problem was compounded by persistent sign theft. These factors led to two efforts to renumber the highway, first by officials in Arizona, then by those in New Mexico. There have been safety improvement projects in recent years, and fatality rates have subsequently decreased.
U.S. Route 163 is a 64-mile (103 km) U.S. Highway that runs from US 160 northward to US 191 in the U.S. states of Arizona and Utah.

State Route 32 (SR-32) is a state highway in Wasatch and Summit Counties in the U.S. state of Utah.

SR-32 runs for 29.053 miles (46.756 km) from US-40 and US-189 north of Heber City to I-80 near Wanship.

State Route 198 is a highway completely within Utah County in northern Utah that connects Santaquin to Spanish Fork via Payson and Salem. The route runs 16 miles (26 km). The entire length of the route is an old routing of US-6 and US-50; a portion of the route was also US-91. These routes were re-aligned or truncated after the Interstate Highway System was constructed through this part of Utah.
Interstate 80 Business is an unofficial business loop of Interstate 80 (I-80) that is 2.26 miles (3.64 km) long and serves as the main street for the US cities of West Wendover, Nevada, and Wendover, Utah, along a roadway named Wendover Boulevard. Wendover Boulevard was originally part of US Route 40 (US 40), which connected California to New Jersey via Nevada and Utah. A portion of the Nevada segment is concurrent with US 93 Alternate, and the entire portion in Utah is coterminous with Utah State Route 58 (SR-58). The Nevada Department of Transportation (NDOT) applied for the business loop designation in the early 1980s, but the designation has never been approved; nevertheless, signs are posted in both states.

The portion of the highway in the US state of Utah is 197.51 miles (317.86 km) long through the northern part of the state. From west to east, I-80 crosses the state line from Nevada in Tooele County and traverses the Bonneville Salt Flats—which are a part of the larger Great Salt Lake Desert. It continues alongside the Wendover Cut-off—the corridor of the former Victory Highway—US Route 40 (US-40) and the Western Pacific Railroad Feather River Route. After passing the Oquirrh Mountains, I-80 enters the Salt Lake Valley and Salt Lake County. A short portion of the freeway is concurrent with I-15 through Downtown Salt Lake City. At the Spaghetti Bowl, I-80 turns east again into the mouth of Parleys Canyon and Summit County, travels through the mountain range, and intersects the eastern end of I-84 near Echo Reservoir before turning northeast toward the Wyoming border near Evanston. I-80 was built along the corridor of the Lincoln Highway and the Mormon Trail through the Wasatch Range. The easternmost section also follows the historical routes of the first transcontinental railroad and US-30S.
Interstate 84 (I-84) is a part of the Interstate Highway System that links Portland, Oregon, to I-80 near Echo, Utah. The 117.38-mile-long (188.90 km) segment in the US state of Utah is the shortest of any of the three states the western I-84 passes through and contains the eastern terminus of the highway. I-84 enters Box Elder County near Snowville before becoming concurrent with I-15 in Tremonton. The concurrent highways travel south through Brigham City and Ogden and separate near Ogden-Hinckley Airport. Turing east along the Davis County border, I-84 intersects US Route 89 (US-89) and enters Weber Canyon as well as Morgan County. While in Morgan County, I-84 passes the Devil's Gate-Weber Hydroelectric Power Plant and Devil's Slide rock formation. Past Morgan, the highway crosses into Summit County, past the Thousand Mile Tree before reaching its eastern terminus at I-80 near Echo.

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.
State Route 30 (SR-30) is a state highway in the U.S. state of Utah. It is the only highway signed as a Utah state route to traverse the entire width of the state.

The western segment is a historic corridor paralleling the pre-Lucin Cutoff routing of the First transcontinental railroad. A portion of the eastern segment has been designated the Bear Lake Scenic Byway as part of the Utah Scenic Byways program. The route was created in 1966 by combining several state highways into a single designation.
