Interstate 420 Georgia


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 through northern reaches of East Point to reenter Atlanta through Lakewood Heights. This portion was built as Georgia 166 in the mid-1960s. 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.

Highway Guides

Western Terminus - Interstate 285/Perimeter Highway - southwest Atlanta, Georgia
Perspective from Interstate 285 north
One half mile south of the historic western terminus of Interstate 420 on Interstate 285 north. Originally the Lakewood Freeway only carried Georgia 166 across the Perimeter Highway to Interstates 75-85. During the mid 1990s Georgia 154 was added to the fold. The two routes overlap from Interstate 285 east to Exit 4 - Lee Highway where the highway overlaps with U.S. 29 northward into Downtown. Photo taken 08/22/03.
Entering the Exit 5 interchange with the west end of the Langford Parkway. The name change from that of Lakewood Freeway to Langford Parkway occurred in 2000. Thus it was after the 1999 exit renumbering of Georgia's Interstates. This explains why the lettering appears newer on these set of signs. Otherwise this freeway to freeway connection is rather substandard with sharp and narrow ramps. Photo taken 08/22/03.
Eastern Terminus - East End of Langford Parkway @ Lakewood Avenue, south Atlanta, Georgia
Perspective from Georgia 166 east
Beyond the Interstate 75-85 junction, Georgia 166/Langford Parkway ascends toward its terminus near the HiFiBuys Amphitheatre. The entertainment complex is situated nearby to the southeast. Otherwise traffic is directed onto local surface streets while Georgia 166 continues east via Lakewood Avenue. Photo taken 08/22/03.
At the Lakewood Avenue interchange, the east end of the freeway portion of Georgia 166, a stub end exists. Now used as a maintenance storage depot, the Interstate 420 mainline would have continued eastward to a merge onto Interstate 20 near its Exit 63. Photo taken 08/22/03.
The end of the Langford Parkway as Georgia 166 enters surface streets. Note that departing traffic is given precedence as descends to grade-level. Photo taken 08/22/03.
Perspective from Georgia 166 west
Traveling north from the ramp end Pictured above. A Georgia 166 westbound shield points the return onto Langford Parkway/Historic Interstate 420 westbound. Interstate 20 itself is approximately four miles to the north at this point. Photo taken 08/22/03.
Westbound Georgia 166 traffic quickly encounters the Interstate 75-85 overlap as it leaves Lakewood Avenue. These overheads indicate that both lanes are defaulted onto the Interstate pair. However, traffic can also continue westward to U.S. 29, Interstate 285, and Campbellton Road as well. Photo taken 08/22/03.
