Arizona has experienced unprecedented growth throughout the state during the past decade. This rapid growth has resulted in sprawling development and significant increases in traffic. The necessity of access management to preserve the function, efficiency and safety of state highways has increasingly been recognized throughout the United States and in Arizona. Without access management, highways intended as through routes gradually degrade to local service routes as areas become developed or urbanized.
ADOT is undertaking a Statewide Access Management Plan in accordance with the policies of the State Transportation Board to develop an access management classification system for the State Highways, and to develop a comprehensive access management manual to guide the uniform application of access management throughout the state.
