State Route 24 Study

Study Update: October 2017

In 2011, ADOT in conjunction with Federal Highway Administration (FHWA), completed a Design Concept Report (DCR) and an Environmental Assessment (EA) for the Gateway Freeway (State Route (SR) 24; formerly SR 802) between the Santan Freeway (SR 202L) and Ironwood Road. The first segment of the SR 24 freeway between SR 202L and Ellsworth Road, including an interim traffic interchange with SR 202L, was completed and opened to traffic in 2014.

Since the ultimate SR 24 freeway build-out is not anticipated until Phase V of the Regional Transportation Plan, ADOT and FHWA are planning an interim roadway that would help serve the transportation needs of the region until funding is available for the ultimate build-out of the freeway. In order to evaluate and incorporate the proposed interim roadway improvement, the DCR was updated in January 2017 and a reevaluation of the EA is currently underway.

The purpose of the interim improvements is to provide a transportation corridor that supports existing and predicted traffic demands and improves connectivity in the region prior to Phase V improvements. ADOT and FHWA also revisited the vertical alignment for the ultimate SR 24 design as a part of interim improvements.

The proposed interim roadway includes two paved travel lanes in each direction separated by a graded median that would be constructed within the footprint of the future SR 24 freeway between Ellsworth Road and Ironwood Road. The interim roadway pavement surface would be used for the ultimate SR 24 freeway build-out. The interim roadway would preserve the access control plan for this corridor and would not change access points or their crossroad locations from what was outlined in the 2011 DCR. The proposed improvements would maintain the horizontal geometry of the 2011 DCR, but would modify the vertical geometry/profile for SR 24 so that the freeway would be at or above grade throughout. A detailed description of the proposed interim improvements can be found in the finalized January 2017 DCR.

Both the 2011 and 2017 final DCR documents have been posted to this project website. The original EA has also been posted to this project website. The EA reevaluation is still underway and anticipated to be complete in late December 2017. The January 2017 DCR shows the right-of-way and SR 24 project lines. The right-of-way and project line work are preliminary and subject to final design modifications. If you would like to be notified via email when the EA reevaluation document is uploaded, please subscribe for email updates on the SR 24.
