Grand-35 Study

The Arizona Department of Transportation (ADOT) has released the Final Environmental Assessment (EA) and Design Concept Report (DCR) for the Grand-35 study, which identifies ADOT’s recommended project to reconstruct the intersection of US 60 (Grand Avenue), 35th Avenue and Indian School Road. Issuance of the EA, along with a Finding of No Significant Impact (FONSI), allows ADOT to move forward with project design, right-of-way acquisition and construction.

The project is being conducted in coordination with the city of Phoenix and Maricopa Association of Governments (MAG). Construction is expected to begin in summer 2026.

ADOT prepared the Final EA in compliance with the National Environmental Policy Act, which requires agencies to evaluate, disclose and identify mitigation for various environmental impacts of a proposed project receiving federal funding before determining whether to proceed with the project. The FONSI represents ADOT’s final decision on the project.

The final documents include and address public comments received during the public comment period for the draft EA and DCR, which was released in October 2023 and included an in-person public hearing.

Right-of-Way Acquisition

Right-of-Way Acquisition Facts

Acquisitions and Relocations will be performed in accordance with Public Law 91-646, The Uniform Relocation Assistance and Real Property Acquisition Act of 1970 (49 CFR Part 24).
If it has been determined that a property is to be acquired as part of a project, an appraisal will be performed to determine the fair market value of the property.
If a property owner does not agree with the determined valuation, they can obtain an appraisal at their own expense and submit it to ADOT for review and consideration. Relocated housing must be decent, safe and sanitary.
Replacement housing assistance can be made within the general area based on availability.
