U.S. Route 60 (Grand Avenue) and Thunderbird Road / Thompson Ranch Road

Study Updates

The Arizona Department of Transportation, in conjunction with the Federal Highway Administration, anticipates the release of the Draft Environmental Assessment and Design Concept Report for US 60 (Grand Avenue) and Thunderbird Road / Thompson Ranch Road on April 23, 2014. The report will be placed under the "documents" tab under this project and include these items:

  • The project's purpose, need and consistency with the goals and objectives of the local transportation plan
  • The project's recommended alternatives, preferred alternative and major design features
  • The social, economic, environmental and other impacts of the project
  • The relocation assistance program and the right-of-way acquisition process
Project Funding

The current Five-Year Transportation Facilities Construction Program for fiscal year 2014 has identified $14.7 million for improvements to Grand Avenue between Loop 101 and Loop 303. The results of current studies will be used to determine if this project will be funded in 2014.

Project Background

In 2008, ADOT prepared a report that recommended further study of top priority projects along Grand Avenue, including the Grand Avenue / Thunderbird Road intersection. It proposed that a study be completed to determine the intersection configuration that would accommodate growth and increased traffic volumes in this area.

In 2009, the Maricopa County Department of Transportation (MCDOT) completed the El Mirage Road, Northern Avenue to Bell Road Final Design Concept Report (DCR). This DCR identified a concept for the Grand Avenue and Thunderbird Road intersection similar to the ADOT Feasibility Report concept.
