The lowest numbered route in Arizona, SR 24 follows the Gateway Freeway along a one mile spur between Loop 202 (Santan Freeway) and Ellsworth Road in south Mesa. The first segment of the Gateway Freeway opened to traffic by Spring 2014, with construction scheduled to begin on the next section by Fall 2020.1 SR 24 will extend five miles east to Ironwood Drive, and will include a diamond interchange with Ellsworth Road along with at-grade crossings at Williams Field Road, Signal Butte Road, Meridian Road, and Ironwood Drive. Anticipated completion of this interim phase is not expected until 2022.1
Long range plans call for a further extension of the Gateway Freeway (SR 24) to a proposed North-South corridor in adjacent Pinal County, but funding has not been allocated for either project.2
SR 24 overlays the Gateway Freeway from a directional interchange with Loop 202 (Santan Freeway) one mile southeast to Ellsworth Road.
Heading south, Ellsworth Road lines the east side of Phoenix-Mesa Gateway Airport (IWA) en route to the town of Queen Creek. The local arterial parallels Loop 202 going north to the Superstition Freeway (U.S. 60).
SR 24 (Gateway Freeway) west joins Ellsworth Road with the Santan Freeway (Loop 202) to Chandler.
