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 Transportation and Trade Corridor Alliance (TTCA) is focused on creating better jobs and higher household incomes by growing value-added industries that bring new money to Arizona. To achieve this mission, Arizona requires modern and efficient infrastructure to ensure effective connectivity to both domestic and global markets. This Roadmap provides strategic direction for the state of Arizona to maximize opportunities for trade development.
