Florida State Road 200
State Road 200 (SR 200) is a major diagonal road in central and northeastern Florida. Its southern terminus is at US 41 (SR 45) in Hernando (Citrus County). Its northern terminus is at SR A1A in Fernandina Beach (Nassau County), at the corner of Atlantic Avenue and Fletcher Avenue. Route description. SR 200 is signed from Hernando through Apache Shores and Stokes Ferry in Citrus County through Marion Oaks to Ocala in Marion County, where it becomes an unsigned route for US 301 north to Callahan. Then it is signed again from Callahan where it's  also signed concurrently with SR A1A. The segment that is overlapped with SR A1A runs along the northern edge of the Four Creeks State Forest, through Italia, and later passes under Interstate 95 at Exit 373. From there it passes through Yulee where it crosses the CSX Kingsland Subdivision and then US 17. East of there it passes through the wetlands of Lofton Creek, and then turns southeast heading through O'Neil. The routes curve back to the northeast climbing the Thomas J. Shave Jr. Bridge over the Amelia River and finally enters Fernandina Beach, where it makes a sharp curve  to the north before turning to the right on Atlantic Avenue, and finally terminates at South Fletcher Avenue.
