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.
