In 1995 the Georgia Senate moved to rename the then Lakewood Freeway to the Arthur Langford, Jr. Memorial Parkway in honor of the former Atlanta city councilman and Georgia state senator.
Proposed eastward extension to I-20 and cancellation
State Route 166, or just "166" as it is known by the locals, was originally supposed to extend (as I-420) from I-20 near Douglasville in the west to the DeKalb Countyseat of Decatur in the east. The eastern portion of this was fought bitterly by residents in court, and was eventually cancelled, along with a number of other interstate highways in Atlanta. The old I-420 was planned to meet the cancelled portion of Georgia 400 near Moreland Avenue, and then end at an interchange with I-20 in Decatur. 166 is multiplexed with S.R. 154 from S.R. 70 (Fulton Industrial Boulevard/Cascade-Palmetto Highway) in the west to the U.S. 29 interchange at Lee Street/Main Street near Fort McPherson in the east.
Since 2003, GDOT has widened 166 between Greenbriar Parkway and Perkerson Road.
