State Route 24 (SR 24), formerly State Route 802 (SR 802), also known as Gateway Freeway and 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. 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.
Route 24 is a controlled-access highway at the intersection of Loop 202's southern leg (Santan Freeway) and Hawes Road, extending southeast near the Phoenix-Mesa Gateway Airport. Currently extending to Ellsworth Road, the future sections of the roadway plan to continue to the southeast, between the airport and the former General Motors Desert Proving Grounds, until reaching Frye Road, when it turns to the east. The road continues along the Frye Road alignment to the Pinal County line.
Within Pinal County, Route 24 is planned to continue east, intersecting a future north-south freeway under study, and reaching an eastern terminus in the general vicinity of Florence Junction, where US 60 and AZ 79 intersect.
