The Arizona Department of Transportation (ADOT) has established a handbook for the private development community as a uniform protocol for requesting new traffic interchanges (TI) or modifications to existing interchanges. The policy requires that private entities proposing the change adequately assess and mitigate impacts of their development on the state highway transportation system. Applicants shall be required to conduct the appropriate level of technical and environmental analysis/studies, public outreach, community involvement, and government relations as determined by ADOT.
The objective of this policy is to manage access, ensure responsible long term planning, ensure optimal operations given future traffic conditions, and reduce the possibility of future failure and required retrofit, as well as associated expenditures of ADOT-owned transportation facilities.
If you have not yet contacted the District Engineer relevant to your request, this should be your first step. District Engineers and contact information are available on the District Map.
We look forward to building partnerships, fostering multi-agency collaborations, and strengthening relationships between ADOT, developers, and the community. This process is an example of agency level implementation of Governor Napolitano’s Growth and Infrastructure Initiative, requiring developers and other relevant entities to evaluate impacts of development on the state system early in the planning process.
