Joint Project Agreements are primarily utilized as a vehicle to provide for the exchange of funds between the Department and other agencies or organizations, or to memorialize in writing any agreement of the parties. Joint Project Agreements (JPA) and Private Sector Agreements (PSA) are essentially the same and carry the same statutory requirements as an Intergovernmental Agreement (IGA). These may involve different parties outside of ADOT and be for different types of arrangements (e.g. projects, private sector or utilities), however, they are all primarily the same.

Coordination of agreement activities requires an awareness on behalf of the Joint Project Administration and the individual requestor on all matters pertaining to the project, such as bid schedules; Transportation Board meeting dates; payment schedules and other agreement conditions, e.g., exchange of property, in-kind services, inspection of facilities, etc.; and status of projects under construction.
