Ernest W. Barrett Parkway (more commonly Barrett Parkway) is a major thoroughfare in the northwestern part of the Atlanta metropolitan area, in the north-central part of Cobb County, in the U.S. state of Georgia. It travels from the southeastern edge of Kennesaw to a point north of Marietta, and continues on in both directions under other names. The portion of Barrett Parkway between Interstate 575 (I-575/SR 5) and US 41/SR 3 (Cobb Parkway) is designated State Route 5 Connector. The road is named after Ernest W. Barrett, the first chairman of the Cobb County Board of Commissioners in the 1960s, after home rule was enacted under a Georgia State Constitution amendment. The initial portion was constructed through Barrett family land, enabling it to be later sold for major development.
Much of the original Barrett Parkway was taken from the two-lane Roberts Road, which generally went from Cobb Parkway (constructed around 1949 for US 41) to Bell's Ferry Road and served an area that was rural in nature. During the 1980s, dramatically-increased land development, most notably the extension of I-75 in 1977 (which cut Roberts Road in half south of Barrett Parkway), the construction of I-575 in 1980, and the completion of the major regional Town Center at Cobb shopping mall in 1986, strained the road to capacity, and was subsequently widened to six lanes (three in each direction, plus turn lanes) with a median by the Cobb County Department of Transportation. Turn lanes were only at the numerous traffic lights. In the mid-1990s, Barrett Parkway was extended by a completely new median-divided highway southwest of US 41 to Burnt Hickory Road, then by widening Ridgeway Road south to SR 120, west of the city of Marietta. This was briefly called West Cobb Parkway (which created potential confusion with Cobb Parkway).
