Interstate 420 represents a planned southern bypass of the Atlanta Central Business District by way of the Lakewood Freeway (Georgia 166). The Interstate was to run east from I-285 in west Atlanta along northern reaches of East Point to reenter Atlanta through Lakewood Heights. This portion was built in the mid-1960s and signed as Georgia State Route 166. The remainder of the route east to Interstate 20 near Gresham Park was unconstructed.

Interstate 420 was approved by AASHTO on June 17, 1975. It was never signed along the Lakewood Freeway however, with I-420 dropped on the Georgia Official Highway Map in 1985. The freeway was renamed Langford Parkway in 1995 to honor Arthur Langford, Jr., a former Georgia State Senator and Atlanta City Councilman.
