shield, modified when the road was given to the county Prior to the 1945 renumbering, State Roads were given numbers in the order they were added to the system. The
1945 renumbering removed many roads that were never built and added some that had not existed
prior to 1945. In 1955, the
State Road Department (SRD) slowed the addition of new state roads and began to classify roads into primary, secondary, and local roads. Primary roads would continue to be state-maintained, while secondary roads would have an S before the number, and would only be state-maintained during a construction project. Local roads would be completely removed from the system. In 1969, the State Road Department was superseded by
Florida Department of Transportation (FDOT). In 1977, House Bill 803 (HB 803), Chapter 77-165 in the
Laws of Florida, was passed in the
Florida Legislature. This transportation policy act eliminated the secondary roads, roads that consisted of county roads that were maintained by the state. When the provisions went into effect on July 1, 1977, the division of roads became state, county, and local. Most secondary roads and some primary roads were given to the counties, and occasionally a new state road was taken over; some main roads in incorporated areas were given to the localities. ==Numbering system==
