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
By the middle of 1930, SR 35 was designated on the unnumbered road south-southeast of Thomasville. Four segments of SR 3 had a completed hard surface: from Thomasville to Albany, from Leesburg to Ellaville, from south-southeast of Thomaston to north-northwest of that city, and from north-northeast of Zebulon to Ringgold. Two segments had a sand clay or top soil surface: from Butler to south-southeast of Thomaston and from north-northwest of that city to north-northeast of Zebulon. Two segments were under construction: from Albany to Leesburg and from Ringgold to the Tennessee state line. By the end of the year, the Albany–Ellaville segment and the Rinngold–Tennessee segment had a completed hard surface. A segment south of Zebulon had a sand clay or top soil surface. From the Florida state line to Thomasville and a segment north-northeast of Zebulon were indicated to be under construction. By the end of 1931, three segments had a completed hard surface: from the Florida state line to Thomasville, a segment north of Ellaville, and a segment north-northeast of Zebulon. Two segments were under construction: from north of Ellaville to Butler and a segment south of Zebulon. In January 1932, the entire highway from Florida to north of Ellaville had a completed hard surface. In April that year, the entire highway from south-southeast of Thomaston to the Tennessee state line had a completed hard surface. A segment south-southeast of Thomaston was under construction. Later that year, the segment from north of Ellaville to Butler had a sand clay or top soil surface. From Butler to the south end of the SR 22 concurrency was under construction. Before the year ended, this segment had a completed hard surface. The segment of SR 3 from the south end of SR 22 concurrency to south-southeast of Thomaston, as well as the segment of SR 35 in the southern part of Thomasville, was under construction. By the middle of 1933, the segment from north of Ellaville to Butler had a completed hard surface. The segment from the south end of the SR 22 concurrency to south-southeast of Thomaston had completed grading, but had no surface course. By the end of the year, all of the then-current path of SR 3 had a completed hard surface. In 1934, the segment north of Ringgold was shifted west to travel northwest from that city. A segment north-northwest of Thomasville, as well as the Pelham–Camilla segment, was under construction. By the end of the year, a segment of SR 35 south-southeast of Thomasville had a completed hard surface. From the Florida state line to south-southeast of the city, this segment was under construction. By April 1935, the central portion of the segment of SR 35 had completed grading, but was not surfaced. By the end of the year, nearly the segment of SR 35 had a completed hard surface. By the middle of 1936, the entire segment of SR 35 had a completed hard surface. Late in 1937, US 19 south of Thomasville was shifted eastward to travel concurrently with this segment of SR 35, with US 319 designated on its former path southwest of Thomasville. SR 3 was split into two parts between Atlanta and the northwest part of Marietta. US 41/SR 3 traveled northwest on the original path, while SR 3E traveled north-northwest on a more eastern path between the two cities. SR 3E's path from SR 120 in the east part of Marietta to US 41/SR 3 in the northwestern part of the city. The rest of SR 3E was under construction. By the end of the year, SR 3W was established, traveling northwest with US 41 on Marietta Street and Old Marietta Road, while SR 3E traveled north-northwest on Hemphill Street and Northside Drive. All of SR 3E in the northern part of Atlanta was hard surfaced. From the north part of the city to the northwest part, the highway had completed grading, but was not surfaced. Later that year, all of SR 3E from Atlanta to northwest of the Fulton–Cobb county line had a completed hard surface.
