129, turns north and heads into Ben Hill County and through Fitzgerald, where it splits from US 129 and first heads east, and then north through the northwestern corner of Coffee County, where it meets up and is co-signed with US 441, and crosses the Ocmulgee River into Telfair County, Georgia at Jacksonville, Georgia and on into McRae-Helena. After briefly traversing the western corner of Wheeler County and eastern corner of Dodge County, US 319 continues north through Laurens County, crossing I-16 just before heading into and through Dublin and East Dublin, where US 441 splits off. Continuing northeast, the route heads into Johnson County, runs through Wrightsville, and heads into southern Jefferson County, where it turns east in Bartow, before meeting its northern terminus at US 1 and SR 4 in Wadley. US 319 from Tifton to the Florida State Line is a GRIP corridor. National Highway System The following portions of US 319 and SR 35 are part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense: US 319/SR 35: From its southern terminus in Apalachicola to just north of the concurrency with US 82/SR 520 just east of Tifton US 319 only: From the southern end of the SR 32 concurrency in Ocilla to about Fitzgerald The entire length of the US 441 concurrency, from south of Jacksonville to Dublin. History Florida The entire length of US 319 in Franklin County was designated as "Blue Star Memorial Highway" by the Florida State Legislature in 1957. The section of US 319 that is co-signed with US 98 and SR 30 in Medart in Wakulla County was designated as "Agnes Morrison Memorial Highway" by the Florida State Legislature in 1961. From Kinhega Drive, about north of its intersection with I-10 in Leon County, to the Georgia state line, US 319 and SR 61 were designated as "Kate Ireland Parkway" by the Florida State Legislature in 1992. Georgia US 319 does not make an appearance on Georgia road maps until October 1937, when the spur from the Florida state line to Thomasville is shown, co-signed with SR 3. Prior to October 1937, US 19 appears as the designation of this section of the route. In July 1941, US 319 was extended from Thomasville, and ran through Moultrie, following what was signed as SR 35 at the time,
