Selected Alternative

The EA process, which includes both the Draft EA and Final EA, was conducted in accordance with the National Environmental Policy Act and has identified a recommended alternative for this intersection. It also formally documents the analysis of potential impacts associated with the proposed alternative. The Draft EA was published on May 1, 2014, and a public hearing was held on May 15, 2014.

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.
