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. Improvements to this corridor would benefit the region by addressing a number of different customers traveling around and through the region.

The City of Prescott was awarded funding to conduct this corridor study through the Planning Assistance for Rural Areas program administered by the Arizona Department of Transportation. The City of Prescott, with support from ADOT, has worked with other local agencies in the region to conduct this study to evaluate and recommend a corridor alignment for the Sundog Connector located in Yavapai County, Arizona. The western corridor terminus is located in the City of Prescott and the eastern terminus is located in the Town of Prescott Valley. The corridor study area is defined as the area between State Route (SR) 69 and Prescott Lakes Parkway. The focus of the study was to document the current and future conditions through a review of all relevant planning studies, land use designation, development plans, needs assessments, and stakeholder input. Using the documented purpose and need for the corridor, the study team has identified, evaluated and recommended a preferred corridor for the planned roadway including alignment, typical sections, recommended right-of-way, and utilities and drainage recommendations.

The primary goals of the study are to define the current circulation system, evaluate its performance, forecast future needs, and prepare a plan for fulfilling the identified needs. The study is prepared for the Town of Sahuarita, pursuant to an intergovernmental agreement with the Arizona Department of Transportation through the auspices of ADOT's small area transportation studies program. The Town of Sahuarita General Plan was adopted in November 1996 to guide development within the town and its sphere of influence. The circulation element contained in the General Plan identifies specific objectives for consideration in the planning and development process.

The Transportation Needs Study is a planning effort undertaken cooperatively by Yuma County and the Multimodal Planning Division of the Arizona Department of Transportation. It has been funded and supported through the Planning Assistance for Rural Areas program of ADOT. The Study addresses the needs of multiple jurisdictions, as well as the needs of neighborhoods within these jurisdictions. It encompasses a mix of uses within developed and undeveloped zoning areas of the Mesa Del Sol and Foothills areas.

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.

The Sahuarita/El Toro Corridor Study is a joint effort by the Town of Sahuarita and the Arizona Department of Transportation. The purpose of the study is to assess the feasibility of a transportation corridor that will provide adequate capacity for the potential future growth of the Town of Sahuarita and surrounding areas as well as increase local and regional connectivity in Pima County. The study is being funded by Federal Highway Administration’s State Planning and Research Program and administered through ADOT’s Multimodal Planning Division. In the completed Town of Sahuarita Transportation Study, it was recommended that El Toro Rd be constructed as a six-lane parkway to alleviate the severely congested principal thoroughfares due to the future growth identified in that study.

The proposed Meridian Road Corridor Study is needed to support the continuing development and growth, occurring and anticipated, in the East Mesa, West Apache Junction, and within Pinal County. The purpose of the Meridian Road Corridor Study is to document conditions along the existing roadway and to develop alternatives that will increase the safety and future level of service of Meridian Road. This study will also establish a roadway footprint and develop the ultimate right‐of‐way requirement for the corridor. Finally, the study will be utilized as a guide for local agencies and future development along the corridor. The study area for the Meridian Road Corridor Study is approximately 13 miles in length.
