The Arizona Department of Transportation, in coordination with Apache County District II and the Fort Defiance Chapter of the Navajo Nation, analyzed the traffic circulation conditions of Navajo Routes 7, 12, 54, 110, and 112 within the Fort Defiance Industrial Area which is designated as a major growth area on the Navajo Nation. The study was funded by the Federal Highway Administration’s State Planning and Research Program and administered through ADOT’s Multimodal Planning Division's Planning Assistance for Rural Areas (PARA) program. The study was initiated to develop a planning strategy to improve the mobility and safety within the Fort Defiance Industrial Area.

This study focuses in the area surrounding the municipalities of: Town of Pima, City of Thatcher and City of Safford. The junction of the two major state routes, US 191 and US 70 is located in the heart of these communities and serves as major arterials for local travelers. Parsons Brinckerhoff has been commissioned by ADOT to perform this preliminary assessment for the development of an alternate route through the Thatcher/Safford/Pima area.

Through the Planning Assistance for Rural Areas program, the Arizona Department of Transportation and the City of Yuma cooperatively conducted the Yuma Expressway Corridor Study to develop a preliminary assessment and feasibility of a proposed corridor alignment along the south and western portions of the City of Yuma.

The study is being funded by the Arizona Department of Transportation Multimodal Planning Division’s Planning Assistance for Rural Areas program.

The historical advantages of Grand Avenue and the railroad that led to the development of the West Valley cities have become a detriment to the further development or redevelopment in the past few decades. There is general agreement that significant improvements are needed for the Grand Avenue Corridor. Identified transportation funds provide an opportunity to develop a more modern transportation corridor along Grand Avenue. This study addresses these concerns by developing, evaluating, and recommending transportation investment options.

Following the completion of the 2005 report, an Act was passed that contained a number of important new and continued funding sources for safety related projects, programs, and initiatives. This required every state to develop a Strategic Highway Safety Plan. This 2007 report represents Phase 1, Development Plan and is a comprehensive, collaborative, high level, statewide safety strategy that will guide Arizona's safety change initiative. The Arizona Department of Transportation was assigned the role of project manager for this SHSP phase by the Governor's Traffic Safety Advisory Council.
