The Multimodal Planning Division (MPD) of the Arizona Department of Transportation has been tasked with identifying corridors throughout the state where improvements to the transportation infrastructure supports the greatest potential commercial and economic benefits. These "Key Commerce Corridors" represent a strategic statewide approach to leverage infrastructure improvements to enhance Arizona's competitive economic position. This document presents the basis for the identification and evaluation of the Key Commerce Corridors.

The State Management Plan documents the procedures of the State of Arizona in managing and utilizing federal funds to assist public, Tribal, private for-profit, and private non-profit passenger transportation systems in Arizona. This document updates the 2007 plan and includes the State’s objectives, policies, procedures, and administrative requirements, in a form that is readily accessible to ADOT staff, the Federal Transit Administration, potential subrecipients, and the public.

The Arizona Department of Transportation is the primary decision maker for federal-aid transportation plans and investments in non-metropolitan areas with populations below 50,000. However, ADOT understands the importance of consulting with local governments before, during, and after the decision making process to ensure participation results in improved transportation system planning, performance and project development. Therefore, ADOT has developed guidelines that outline the consultation process, and defines how and when outreach will occur with officials from rural areas. It is intended that this document is subject to review and revision every 5 years. In the event that Congress enacts new transportation language, this document will be subject to immediate revision.
