The CANAMEX Corridor Project is a joint project of Arizona, Nevada, Idaho, Utah and Montana, with the primary objective of developing and implementing the CANAMEX Corridor Plan. The Plan provides areas of collaboration by the states with the goals of stimulating investment and economic growth in the region and enhancing safety and efficiency within the corridor. A comprehensive and coordinated plan will ensure the efficient allocation of resources along the corridor necessary to maximize the economic potential for the US, Canada and Mexico.

CANAMEX includes transportation, commerce and communications components. The transportation component calls for the development of a continuous four-lane roadway from Mexico through the US CANAMEX states, into Canada.

The term CANAMEX is far more than a line on a map or a specific highway, however. Recognition must be given to the fact that the area that would benefit from CANAMEX development extends well beyond the highway. People and products may enter or leave the CANAMEX at any point. Consequently, integrated development of the entire CANAMEX Corridor provides the extensive benefits to the region.

The Arizona Department of Transportation, as the lead state, received in FY 99 $1 million from TEA 21, National Corridor Planning and Development (NCPD) funds to develop a comprehensive plan of the CANAMEX Corridor including strategies for addressing deficits and needs along the Corridor.
