The Arizona Department of Transportation (ADOT), in cooperation with the Federal Highway Administration (FHWA), is initiating a corridor study along State Route 86 (SR 86) within the City of Tucson in Pima County, Arizona. The study limits extend approximately 5.5 miles across land under the jurisdiction of the City of Tucson and Pima County, from Kinney Road at milepost (MP) 166.3 to Holiday Isle Boulevard at MP 170.9. Holiday Isle Boulevard is located approximately 0.2 miles west of the Santa Cruz River. The purpose of this study is to investigate concepts to accommodate projected regional increases in traffic volumes, recommend improvements and present a phased construction plan. SR 86/Ajo Way is a regional transportation route on the western edge of the Tucson metropolitan area, connecting Kitt Peak, Sasabe and other populated areas with the employment centers in Tucson. In recent years the Tucson urban area has started expanding to the west. Because of this growth SR 86 is experiencing a steadily increasing volume of commuter traffic between the developing residential areas to the west and the employment destinations in Tucson.
As part of this study, a Planning and Environment Linkages (PEL) process is underway to integrate environmental, community, and economic goals into the transportation planning process. Funding for design and construction of transportation projects within the study limits is not yet planned or programmed.
This study began in August 2015 and will produce a comprehensive project assessment in accordance with PEL guidelines. The study will be finalized in April 2016.
