It includes much of central Arizona. The United States Office of Management and Budget designates the area as the Phoenix–Mesa–Chandler Metropolitan Statistical Area (MSA), defining it as Maricopa and Pinal counties. It anchors the Arizona Sun Corridor megaregion along with the second-most populous metropolitan area in the state, the Tucson metropolitan area.

Arizona State Route 51 (SR 51), also known as the Piestewa Freeway, is a numbered state highway in Phoenix, Arizona. It connects Interstate 10 and Loop 202 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.

The river then flows through a small canyon called "Black Canyon" into Lake Pleasant, a popular recreation area near Peoria, Arizona. (There is a large "Black Canyon" on the Colorado River along the Arizona–Nevada border.)

Wurzbach Parkway is a part freeway and part major arterial road in San Antonio, Texas, built to provide relief on Interstate 410 (I-410) and Loop 1604 on the city's north side. The highway is named for Harry M. Wurzbach, who represented the San Antonio area in Congress as a Republican in the 1920s and 1930s. The congressman's name was first applied to the connecting Wurzbach Road. The highway's western third was built as an expressway with at-grade intersections and the remainder as a freeway. The opening in September 2015 of an interchange with U.S. Highway 281 completed primary construction of the parkway. The highway, along with part of Wurzbach Road near the Ingram Park Mall, is maintained by the Texas Department of Transportation despite not carrying a state highway designation. Rather, it is being developed and maintained under the Principal Arterial State System (PASS) program, under which it is designated as PASS Project 1502. The parkway includes an interchange with US 281, and drivers can access I-10 and I-35 via local roads that extend the parkway.

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.
