The Pinal North–South Freeway is a planned freeway in the extreme southeastern region of the Phoenix Metropolitan Area currently under study by the Arizona Department of Transportation (ADOT). If constructed, the roadway would serve as a Phoenix–Mesa bypass for cities and suburbs in far eastern Maricopa County and northwestern Pinal County.
The exact route of the freeway has yet to be determined, but the corridor currently under study by ADOT has the southern terminus at Interstate 10 (I-10) between Eloy and Picacho. From I-10 the route would either parallel or replace State Route 87 (SR 87) northward to Coolidge and Florence (serving as a potential eventual terminus of the planned Hassayampa Freeway) before crossing over SR 287 and continuing northward towards a planned intersection with the future alignment of the Williams Gateway Freeway east of Queen Creek. Continuing north, the freeway would either parallel or replace Ironwood Road to its northern terminus in either Apache Junction, at or near the existing SR 88 interchange with the Superstition Freeway, or farther east at the planned realignment of US 60 south of Gold Canyon.
