An Interchange Justification Report (IJR) is required if a roadway project proposes a new interchange on a limited-access facility, such as Interstate 75 (I-75). Florida Department of Transportation (FDOT) Procedure No. 525-030-160, Interchange Justification, defines the state and federal requirements and the processes to be used when developing an IJR. The purpose of an IJR is to demonstrate the need for the project and its viability based on traffic, engineering, financial and other criteria.
The Federal Highway Administration (FHWA) regulates the addition of access points along the interstate system, and has determined that proposed new interchanges must meet the following eight requirements:
FHWA approval of new access points on the Interstate Highway System is considered a Federal Action. This requires approval of the IJR document, as well as National Environmental Policy Act (NEPA) document approval which is obtained through FDOT's PD&E process.
