In the mid-1970s, theFlorida 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 ofFlorida 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").
In 1977, House Bill 803, Chapter 77-165 in theLaws of Florida, was passed in theFlorida Legislature. This transportation policy act eliminated the State Highway Secondary System which consisted of county roads that were maintained by the state.[1][2] The provisions went into effect on July 1, 1977.
State Road signs started disappearing from the "C" roads and were replaced byManual 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 weredecommissioned in later years skipped the prefix step.
The following is a list offormer state roads in Florida:
State Road 5A (nowCounty Road 5A): Flagler Street from First Street to South Roosevelt Boulevard (SR A1A) in Key West. Commercially prepared road maps still indicate incorrectly that CR 5A is still a State Road (when it was, it was not signed as such). Some maps even suggest that it includes White Street between US 1 and Flagler Street.[3]
State Road 150 (nowCounty Road 150) – two sections: one fromUS 19/US 27 in rural Madison County toUS 221 inGreenville; another fromUS 90 east of Greenville to formerSR 152 in Hamilton County.
State Road 167 (nowCounty Road 2301 andCounty Road 167) – two sections: one fromUS 231 inBayou George north of Panama City toSR 20 west ofFountain, now CR 2301; another fromUS 231 in Betts through the northwest corner of Calhoun County then into Jackson County where it eventually joinsSR 267 south of Marianna. After I-10, the road branches off to South Street and runs east until joining SR 73, where it turns north until the intersection with US 90. Here SR 73 turns west, and CR 167 joinsSR 166, until it turns onto "Old US Road" and runs north toward the Alabama State Line.
State Road 259 (nowLeon /Jefferson County Road 259) - also known as "The Old Tram Road," Tram Road, Limestone Road, Wacissa Highway, and Waukeenah Highway, is a bi-county route that serves southeasternLeon County and westernJefferson County, Florida. The western terminus is an intersection with Monroe Street (SR 61) inTallahassee; the northern terminus is an intersection withUS 19 (SR 57) inMonticello. Communities served along its route also includeCorey,Cody,Limestone,Wacissa,Thomas City,Waukeenah, andCasa Blanco. Leon County Road 259 is signed east–west, while Jefferson County Road 259 is signed east–west on Tram Road and Paradise Road, and signed north–south betweenSR 59 and the northern terminus.[4]
State Road 313, now coming back and being built from SR-207 at the intersection with SR-312 to SR-16 as a six-lane road to ease congestion in the St Augustine area.
State Road 905A (nowCounty Road 905A) is the Card Sound Bridge and Card Sound Road between the bridge andCR 905 (SR 905A used to extend northward to an intersection withUS 1 nearFlorida City, butMiami-Dade County doesn't sign its county roads and rarely designates them as "County Road ###"). As late as 2005, an old "State Road S-905A" was still posted near the intersection with CR 905.
State Road 940 (northern segment nowCounty Road 940): Big Pine Avenue and Elma Avenue onBig Pine Key. This is the only state road – current or former – that has segments on both sides of theOverseas Highway. A street extending eastward from Big Pine Avenue ontoNo Name Key is locally known asSR 4A (see "State Road 5", above). Much of Big Pine Avenue is located inNational Key Deer Refuge.
