State Route 80 (SR 80) is a 120.20-mile (193.44-kilometre) long, roughly arc-shaped highway lying in southeastern Arizona. Starting in downtown Benson, the highway serves as the main route through the towns of St. David, Tombstone, Bisbee and Douglas before terminating at the New Mexico state line, becoming New Mexico State Road 80 (NM 80). SR 80 also acts as the national southern terminus of US 191 near Douglas and provides the only connection between the U.S. Highway and its business route in Douglas.
State Route 79, also known as the Pinal Pioneer Parkway, is a 58.40 mi (93.99 km) long state highway in the U.S. state of Arizona. It serves as the main route through the town of Florence, which is also the county seat of Pinal County. Although the highway has been part of the state highway system since at least 1926, it was not designated as SR 79 until 1992. The highway was previously a section of U.S. Route 80 and U.S. Route 89 between Phoenix and Tucson, until both highways were decommissioned in 1977 and 1992 respectively. SR 79 is also the only state highway in Arizona that has a business route, which is SR 79 Business through downtown Florence. SR 79 is also notable for being the location where cowboy western actor Tom Mix died in a car accident on October 14, 1940.
State Route 120 is a state highway in the central part of California, connecting the San Joaquin Valley with the Sierra Nevada, Yosemite National Park, and the Mono Lake area. Its western terminus is at Interstate 5 in Lathrop, and its eastern terminus is at U.S. Route 6 in Benton. While the route is signed as a contiguous route through Yosemite, the portion inside the park is federally maintained and is not included in the state route logs. The portion at Tioga Pass at Yosemite's eastern boundary is the highest paved through road in the California State Route system. This part is not maintained in the winter and is usually closed during the winter season.
State Route 89A is an 83.85-mile (134.94 km) state highway that runs from Prescott north to Flagstaff in the U.S. state of Arizona. The highway begins at SR 89 in Yavapai County and heads northward from Prescott Valley, entering Jerome. From Jerome, the route then heads to Cottonwood and Clarkdale. The road then continues out to Sedona. The highway is notable for its scenic value as it winds over and through Mingus Mountain as well as passing through Sedona and the Oak Creek Canyon. The route then enters Coconino County soon after leaving Sedona. The highway proceeds to Flagstaff, where it crosses Interstate 17 (I-17) and I-40. The highway ends at I-40 Business in Flagstaff. What is now SR 89A became a state highway in the late 1920s as SR 79. The highway was extended and improved several times through 1938. SR 79 was renumbered to U.S. Route 89A in 1941 and then to SR 89A in the early 1990s.

At 305.777 miles (492.100 km), it is the third longest California state route, after Route 1 and Route 99, and the longest east-west route. Route 299's western terminus is at US 101 at the northern edge of Arcata, and its eastern terminus is at the Nevada state line at a point east of Cedarville. Between Arcata and Redding, Route 299 intersects with State Route 96, and is briefly co-signed with State Route 3. In Redding, it intersects with State Route 273, State Route 44, and Interstate 5. East of Redding, it intersects with State Route 89, and a section is co-signed with State Route 139 before reaching Alturas. It is then co-signed with U.S. Route 395 northeast of Alturas, and then runs east through Cedarville and to the border with Nevada. A ghost town, Vya, Nevada, can be reached via this route, which after the border becomes a dirt road, which was formerly Nevada State Route 8A. The segment of SR 299 between Arcata and Redding is the Trinity Scenic Byway, a National Forest Scenic Byway.

Both segments are also signed as Interstate 80 Business, which is also signed along the city-maintained segment of Idaho Street between the two NDOT segments as well as the city-maintained segment of Idaho Street east of the final eastern terminus all the way to East Jennings Way, from which it connects to the Elko East exit on Interstate 80. Most of Interstate 80 Business in Elko, including both segments of SR 535, were formerly designated U.S. Route 40.
U.S. Route 93 (US 93) is a United States Numbered Highway in the state of Arizona that begins in Wickenburg and heads north to the Nevada state line at the Mike O'Callaghan–Pat Tillman Memorial Bridge.

While most of US 93 is a four-lane divided highway, sections of the highway between Wickenburg and I-40 are still narrow two-lane roads, gradually being upgraded to match the rest of the route. As part of a proposal by municipal leaders in Nevada and Arizona, the highway could be replaced by Interstate 11 (I-11).
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 runs concurrently with US 93 Alternate, and the entire portion in Utah is coterminous with 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. Between July 1976 and 1993, I-80 Bus was concurrent with State Route 224 (SR 224) in Nevada.
