Georgia State Route 166
highway in Georgia
State Route 166 (SR 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 (formerly named the Lakewood Freeway).
SR 166 was originally the Georgia segment of U.S. Route 78S (US 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 (I-420), but that project was cancelled.

Why this record matters
The phrase “highway in Georgia” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Nov 29, 2025. The linked authority identifier is Q2428140. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
