context_page_description: State Route 166 is a state highway in the U.S. state of Georgia. It connects the Alabama state line with the city of Atlanta. The highway travels through Carrollton, McWhorter, and East Point. Except for the Carrollton and East Point/Atlanta areas, the highway is fairly rural. In Atlanta, it has a limited-access freeway portion that is known as the Arthur B. Langford Jr. Parkway.
  SR 166 was originally the Georgia segment of U.S. Route 78S, which was later redesignated as US 78 Alt. The Lakewood Freeway portion of this highway was, at one time, slated to become designated as Interstate 420, but that project was cancelled.
