Arizona State Route 24
state highway in Maricopa and Pinal counties in Arizona, United States
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.
In earlier planning stages, the freeway was formerly labeled State Route 802 (SR 802).
