Georgia State Route 5
Between August 1950 and the beginning of 1952, the entire Powder Springs–Marietta segment had a completed hard surface. A portion north-northeast of McWhorter had a sand clay or top soil surface. In 1953, the northern two-thirds of the McWhorter–Douglasville segment was hard surfaced. A portion east of Roopville had a sand clay or top soil surface. Three segments had completed grading, but was not surfaced: from the Alabama state line to Roopville, the Carroll County portion of the Whitesburg–McWhorter segment, and a portion north-northeast of McWhorter. Between June 1955 and July 1957, a portion east of Roopville had completed grading, but was not surfaced. Between July 1957 and June 1960, three segments were paved: the central portion of the Bucktown–Roopville segment, the western half of the Roopville–Whitesburg segment, and from southwest of Whitesburg to north-northeast of McWhorter. By June 1963, the segment from west-northwest of Tyus to Roopville was paved. By the end of 1965, the segment from the Alabama to east-southeast of Lowell was hard surfaced. The segment from east-southeast of Lowell to south-southwest of Whitesburg had a "topsoil or gravel" surface. At this time, SR 5 Byp. was built and hard surfaced from US 76/SR 5 southwest of Blue Ridge to SR 5 north of the city. In 1966, SR 5 was hard surfaced from Alabama to Douglasville. In 1973, SR 705 was proposed from SR 3 (Church Street) in Marietta to SR 5 south of Blackwell, with an interchange with I-75. In 1977, I-575/SR 713 was proposed from I-75 north of Marietta to just south of the Cherokee–Pickens county line. It was completed from SR 140 south of Canton to SR 20 east of the city. The next year, the entire Cobb County portion (except for the southern end) of I-575/SR 713 was under construction. SR 5 through Blue Ridge was shifted westward, replacing the entire length of SR 5 Byp. Its former path through the city was redesignated as SR 5 Bus. By the end of the decade, SR 733 was proposed between two intersections with US 76/SR 5 northeast of Ellijay. At this time, SR 734 was proposed from US 76/SR 5 south-southwest of Cherry Log, across US 76/SR 5 north-northeast of Cherry Log, and then to another intersection with US 76/SR 5 in Lucius.
Georgia State Route 3
SR 3 was established at least as early as 1919 starting at the Florida state line southwest of Thomasville; no numbered highway extended south-southeast from that city at the time. SR 3 traveled on essentially the same path as it currently does. The main differences were the southern terminus and the northern terminus. It traveled north from Ringgold to the Tennessee state line. By the end of 1926, US 41 had been designated on the entire length of SR 3 from Griffin to the Tennessee state line. Seven segments of the highway had a "completed hard surface": a segment in the northern part of Thomasville, from approximately Ochlocknee to north-northeast of Camilla, from the Mitchell–Dougherty county line to Albany, from south of Americus to Ellaville, from north-northeast of Zebulon to just south of the Spalding–Henry county line, from just north of this county line to just south-southeast of the Henry–Clayton county line, and from just north-northwest of this county line to Marietta. Five segments of the highway had a "completed semi hard surface": a segment south of the Mitchell–Dougherty county line, from Leesburg to the Lee–Sumter county line, from Cartersville to the southeastern part of Calhoun, a segment in the northwestern part of Dalton, and from Ringgold to the Tennessee state line. Ten segments of the highway had a "sand clay or top soil" surface: a segment on both sides of the Grady–Thomas county line, a segment north-northwest of Thomasville, from Ellaville to north-northeast of Rupert, a segment just north-northeast of Butler, from the south end of the SR 22 concurrency to south-southeast of Thomaston, from south of the Upson–Pike county line to Zebulon, a segment in the northwestern part of Marietta, from just south of the Cobb–Bartow county line to Cartersville, from just south of the Gordon–Murray county line to Dalton, and from northwest of Dalton to Ringgold. Six segments of the highway were indicated to be under construction: a segment north of the Lee–Sumter county line, from south-southeast of Thomaston to north-northwest of that city, a segment north-northeast of Zebulon, from just south of the Spalding–Henry county line to just north of that line, from northwest of Marietta to just south of the Cobb–Bartow county line, and from the southeastern part of Calhoun to just south of the Gordon–Murray county line. By the end of 1929, US 19 was designated on the then-current highway from the Florida state line to Atlanta. Also, an unnumbered road was built on the current path of SR 3 south-southeast of Thomasville.
