Road Naming and Numbering
State Road numbers are assigned by FDOT and County Road numbers by the counties. U.S. and Interstate numbers are approved by the American Association of State Highway and Transportation Officials (AASHTO). State Road numbers should conform as much as possible to Section 335.08 F.S.:
Florida Statute 335.08 – Determination of Road Number.
- The department is authorized to number and renumber the roads of the State Highway System and to advise the counties and municipalities on the numbering of the roads in their respective road systems.
- The department may establish a systematic numbering plan, giving even numbers to roads extending in the general direction of east and west, and odd numbers to roads extending in the general direction of north and south

Every State Road must have a State Road (SR) number. Any County Road may have a County Road (CR) number, but is not required to do so. Every SR and CR number that is in use must apply to only one road. This road may be discontinuous, but two separate segments with the same SR or CR number must have a logical and sequential connection between them. A road must never split into two different roads with the same SR or CR number, unless it is to allow for a one-way pair to connect to a two-way road. Currently there is no minimum length requirements for a state road.
Retaining the Road Number from the Previous System Following a transfer, a road may retain the same road number but with a different prefix (e.g. change from CR 99 to SR 99), unless this results in duplicate numbers for different roads. In such cases, TDA and the District shall locate and assign an appropriate vacant State Road Number.
Interstate establishment requires Federal Highway Administration (FHWA) and the American Association of Safety and Highway Transportation Officials (AASHTO) approval. Corridors must be built to interstate standards. See the Transportation System Designations and Road Jurisdiction Transfer Handbook for the steps.
MEMORIAL ROADWAYS (LEGISLATIVE)
Consists of designating a transportation facility, contained in an act of the Legislature, for honorary or memorial purposes or to distinguish it as a particular facility. The Florida Legislature designates memorial roadways based on recommendations from a city or county commission, individual state agency, or civic groups. Memorial Roadway Designations are not maintained by the TDA Office. Additional information can be found on the Systems Implementation Office’s Memorial Roadway Designations web page.
LOCAL ROAD NUMBERS
Local entities are not required to adhere to the State Road Numbering System and guidance for local road naming is provided in Florida Statutes for the situations to follow. The District should encourage and implement methods to coordinate with local entities through signed petitions, public meetings and updating all parties involved (law enforcement, 911 responders, utility providers, FDOT, residential and commercial property owners, etc.); should the road number change.
LOCAL ROAD NAMING
Local road names are the jurisdiction of the local government:
a. County: Florida Statute 336.05: “The commissioners are authorized to name and rename streets and roads, except State Roads designated by number by the department, lying outside the boundaries of any incorporated municipality.”
b. Municipality: Florida Statute 166.021: “Municipalities shall have the governmental, corporate, and proprietary powers to enable them to conduct municipal government, perform municipal functions, and render municipal services, and may exercise any power for municipal purposes, except when expressly prohibited by law.”
c. Bridges: For state owned bridges, the legislature has the authority to officially name a bridge. This requires a bill that would be signed by the Governor. This would apply to Interstates, U.S. Routes and State Routes. Bridges on County highways or local roads could be named by the respective owners.
LOCAL ROAD NAME/NUMBER CHANGE PROCESS
See the Transportation System Designations Road Jurisdiction Transfer Handbook for process steps.
PUBLIC HEARING OPPORTUNITY
After it has been determined that a road number will change, the District should send notices to emergency service providers, the Post Office, and other interested parties. The number of notices/meeting-places advertised is at the discretion of the District and may depend on general acceptance of the project by the local citizens, the number of people affected, and their familiarity with the change. If the City/County is transferring a road to the State, the District can suggest notifications be sent to emergency service providers, the Post Office, and other interested parties, but cities/counties are not required to follow FDOT’s advice.
The District should maintain all pertinent information about the road number change in its project files for historical reference.
