Florida Highway Systems, Numbering and Jurisdiction

Picture of a Florida Roadway
The Transportation Statistics Office coordinates and maintains data on various highway system designations. Federal Aid Systems, the National Highway System, functional classification, and urban boundaries are developed in a cooperative process with local officials and FDOT according to Federal Highway Administration (FHWA) requirements, and approved by FHWA before becoming effective. The SIS and FIHS are designated by FDOT, with input from local governments, highway users, and other interested parties.

State Road numbers are assigned by FDOT, and County Road numbers by the counties (with guidance from FDOT). US and Interstate numbers are approved by the American Association of State Highway and Transportation Officials (AASHTO).
