State Route 24: Ellsworth Road to Ironwood Drive
Interim Phase II

Overview

The Arizona Department of Transportation, in conjunction with the Federal Highway Administration, is currently designing the Interim Phase II section of State Route 24 (SR 24) also referred to as Gateway Freeway.  This section will include approximately five miles of new freeway extending from Ellsworth Road in Maricopa County to Ironwood Drive in Pinal County. The project is currently in the final design phase with construction anticipated to begin in Fall 2020.

The Interim Phase II segment of SR 24 follows the completion of Phase I in 2014, which opened the segment of freeway between State Route 202 (Loop 202/Santan Freeway) and Ellsworth Road.

Since the ultimate build-out of State Route 24 is not anticipated until Phase V of the Maricopa Association of Governments’ Regional Transportation Plan, ADOT and FHWA have planned for an interim facility that will help serve the transportation needs of the region until additional funding is made available. The interim facility will preserve the access control plan for this corridor outlined in the 2011 Design Concept Report, and be built at-or-above grade throughout.

Features of the new roadway will include:

  • Two paved lanes in each direction separated by a graded median.
  • At-grade intersections at the following locations:
    • Ellsworth Road
    • Williams Field Road
    • Signal Butte Road
    • Meridian Road
    • Ironwood Drive 
  • A grade separation at Mountain Road.
  • A drainage channel along the north side of the freeway.
  • Signage, traffic signals, lighting and pavement marking, as necessary.

Recent project updates include:

  • Bridges on State Route 24, in each direction, over Ellsworth Road.
