State highways in Arizona

Arizona State Route 303 (SR 303) or Loop 303, also known as the Bob Stump Memorial Parkway (formerly the Estrella Freeway), is a freeway that serves the west part of the Phoenix metropolitan area. The freeway, originally a two-lane rural highway, was maintained by Maricopa County until 2004 after approved sales tax when the Arizona Department of Transportation again took control of upgrading the interim road to a freeway.

State Route 24 (SR 24), also known as the Gateway Freeway or the Williams Gateway Freeway, is a freeway in the extreme southeastern region of the Phoenix Metropolitan Area. The roadway is planned as a controlled-access highway to move traffic from the southeastern suburbs of Phoenix to planned ones in northwestern Pinal County. It is the lowest-numbered state route in Arizona. The first mile from Loop 202 to Ellsworth Road opened on May 4, 2014. An extension to Ironwood Drive opened in 2022, with the completion of "Interim Phase II"; the first mile of this extension from Ellsworth Road to Williams Field Road opened on April 1, 2022, with the remainder following on August 11. Planning for future sections has been halted until studies for the Pinal North-South Freeway are completed to confirm how the two freeways will intersect.

State Route 73, also known as SR 73, is a U-shaped state highway, though it is signed north–south, primarily serving the Fort Apache Indian Reservation in eastern Arizona. SR 73 begins at a junction with the U.S. Route 60 / State Route 77 concurrency near Carrizo, travels southeast to Fort Apache and Whiteriver, then bends north-northeast until intersecting State Route 260 near the Hon-Dah Resort Casino.

Arizona State Route 202 (SR 202) or Loop 202 (202L) is a semi-beltway circling the eastern and southern areas of the Phoenix metropolitan area in central Maricopa County, Arizona. It traverses the eastern end and the southern end of the city of Phoenix, in addition to the cities of Tempe, Mesa, Chandler, and Gilbert, and is a vital route in the metropolitan area freeway system. Loop 202 has three officially designated sections along its route; the Red Mountain Freeway, the SanTan Freeway, and the Congressman Ed Pastor Freeway, also known as the South Mountain Freeway. The Red Mountain Freeway runs from the Mini Stack Interchange with Interstate 10 (I-10) and State Route 51 (SR 51) in Phoenix to the SuperRedTan Interchange with U.S. Route 60 (US 60) in Mesa. The SanTan Freeway runs from there to an interchange with Interstate 10 (I-10) in Chandler. The Congressman Ed Pastor Freeway runs from there to I-10 in western Phoenix.

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.

Arizona State Route 76 (SR 76) was a short state highway in eastern central Arizona, United States that connected State Route 77 to the San Manuel Copper Mine and San Manuel with a detached southern segment connecting Pomerene to Benson. The highway was planned to be completed through Pima County between Pomerene and San Manuel. However, it was never completed, and the next planned segment was abandoned during construction. Two other sections were constructed north of Pomerene and south of Redington but were never formally designated SR 76 or connected to the rest of the route.

State Route 366 (SR 366) is a highway in Graham County, Arizona that runs from its junction with US 191 south of Safford to near the summit of Mount Graham. It is a winding mountain road with one half primarily a northwest-southeast route, the other half being northeast-southwest.
