Outer Perimeter was an expressway originally planned to encircle
Atlanta about 20 to 25 miles (about 30 to 40 km) further away
from the city than the existing Perimeter Highway (I-285).
original plan of the highway was to have roughly gone through or
near the communities of Cartersville, Canton, Cumming, Buford,
Dacula, Loganville, Conyers, McDonough, Hampton, Newnan,
Peachtree City, Villa Rica, and Dallas. roadway was to have
roughly paralleled State Route 20 , which goes around three

crossed it: I-75; I-575 ; Georgia 400 The Northern Arc was to
have been a toll under another proposal, which advocates say
would have kept most local traffi
