State Route 85 is a 128.86-mile-long (207.38 km) state highway in the U.S. state of Arizona. The highway runs from the United States–Mexico border near Lukeville to the north ending at Interstate 10 (I-10) in Buckeye.

Arizona State Route 51 (SR 51), also known as the Piestewa Freeway, is a numbered state highway in Phoenix, Arizona. It connects Interstate 10 just outside Downtown Phoenix with Loop 101 on the north side of Phoenix, making it one of the area's major freeways. It is a largely north–south route and is known for traversing the Piestewa Peak Recreation Area. The peak was named after Lori Piestewa, the first Native American woman to die in combat in the U.S. military. Prior to this time, the freeway was known as the Squaw Peak Parkway, a name considered offensive by Native Americans. Rapid growth and increased traffic demand on the east side of Metro Phoenix made the Piestewa Freeway necessary.

Interstate 11 (I-11) is an Interstate Highway that currently runs for 22.8 miles (36.7 km) on a predominantly northwest–southeast alignment in the US state of Nevada, running concurrently with US Route 93 (US 93) between the Arizona state line and Henderson. The freeway is tentatively planned to run from Nogales, Arizona, to the vicinity of Reno, Nevada, generally following the current routes of I-19, I-10, US 93, and US 95. Planners anticipate widening two existing highway segments to carry future I-11: US 93 in Arizona from Wickenburg to the Nevada state line on the Mike O'Callaghan–Pat Tillman Memorial Bridge over the Colorado River, and US 95 in Nevada from the Las Vegas Valley to Tonopah. In 2022, officials in Nevada announced that they planned to extend I-11 through the Las Vegas Valley along the existing alignments of I-515/US 93/US 95 to downtown Las Vegas, then running concurrently with US 95 northwest to SR 157. An exact alignment for I-11 has yet to be determined outside of these sections; however, a number of corridor alternatives have been identified for further study and refinement. The building of I-11 in Arizona is also facing local opposition from conservation groups.

Route 153 was a north–south route that skirted the eastern edge of Sky Harbor International Airport, and along with SR 143, SR 153 served a portion of East Valley residents with access to the airport.

Many arterial roads in the Phoenix metropolitan area have the same name in multiple cities or towns. Some roads change names or route numbers across town borders, resulting in occasional confusion. For example, the road known as Apache Boulevard in Tempe continues east as Main Street in neighboring Mesa and then as Apache Trail in Apache Junction. Although Broadway Road maintains the same name through Goodyear, Avondale, Phoenix, Tempe, Mesa, and Apache Junction, each town uses a different reference point for address numbers.
