List of former state roads in Florida

In the mid-1970s, the Florida Department of Transportation (formerly the State Road Department) started a sequence of events that eventually resulted in the transferral of hundred of miles of roadway from State of Florida maintenance to county control. The first step was the addition of an "S-" or "C-" prefix onto the original FDOT designation ("S" represented "secondary"; "C" represented "county"). State Road signs started disappearing from the "C" roads and were replaced by Manual on Uniform Traffic Control Devices (MUTCD) compliant county road signs in the early 1980s; the transition of "S" roads to county control took a bit longer. Many roads that were decommissioned in later years skipped the prefix step.

While the transition occurred throughout the State of Florida, the area most dramatically affected by this process was Florida south of State Road 70 (SR 70) (which runs from Bradenton to Fort Pierce). Several state roads had portions turned over to their respective county jurisdiction and there were cases where entire state roads segments were turned over to the respective county jurisdiction. The following is a list of former state roads in Florida.
