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.

By March 1980, I-575/SR 713 was completed to SR 92 southwest of Woodstock and one exit to the south in the Canton area. SR 713 was proposed to be extended northwest to SR 5 in Talking Rock. SR 713 Spur was proposed from SR 5 to SR 713 at the northern terminus of I-575. SR 719 was proposed from SR 5 south-southwest of Ellijay to US 76/SR 5 northeast of that city. Later that year, the southern completed part of I-575/SR 713 was extended south to I-75. The next year, SR 5's path from south of Nelson to southeast of Talking Rock was shifted westward, replacing SR 713 Spur and the northern extension of SR 713. The former path of SR 5 was redesignated as SR 5 Alt. At this time, SR 719 was under construction. In 1982, I-575/SR 713 was under construction from SR 92 southwest of Woodstock to south of Canton and from east of Canton to I-575's northern terminus north-northwest of Ball Ground. SR 713 was proposed to be extended northwest to SR 5 west-northwest of Talking Rock and north to the southern terminus of SR 719 at SR 5. The next year, SR 5's path from Powder Springs to Marietta was shifted eastward, replacing SR 340. I-575/SR 713 was completed from SR 92 southwest of Woodstock to south of Canton. SR 5 in the Ellijay area was shifted eastward. US 76/SR 282 was extended southeast to East Ellijay to rejoin it. This shifting of SR 5 replaced SR 719. The former path of SR 5 was redesignated as SR 5 Alt. In 1985, SR 5's path from Marietta to northeast of Canton was shifted westward, onto I-575. Its former path from Marietta to Lebanon was redesignated as SR 754. I-575 was completed northeast to a point southwest of Ball Ground. SR 5's path from Talking Rock to south-southwest of Ellijay was shifted westward, replacing all of SR 713. In 1986, all of I-575 was completed. SR 5's path from northeast of Canton to north-northwest of Ball Ground was shifted westward, onto I-575. The northern part was redesignated as a northern extension of SR 372. Between 1981 and 1986, SR 5's path in the Ball Ground–Nelson area was shifted westward, onto I-575. Part of the former path was redesignated as a northern extension of SR 372. In 1989, SR 515 was designated on SR 5 from I-575's northern terminus west of Nelson to Blue Ridge. Between 1984 and 1991, US 76/SR 5/SR 515 was shifted onto the path of SR 733 and SR 734, replacing them.
