Most of the county roads in Collier County were formerly state roads. In the mid 1970s, the Florida Department of Transportation (formerly the State Road Department) downgraded a number of the state roads to secondary state roads. On January 5, 1976, many of the roads were also renumbered to have a more streamlined numbering system. By the mid 1980s, the secondary state roads were turned over to county control.
