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 sides of Atlanta.
incarnation of the highway only encompassed what was termed the
Northern Arc and included the portion of the
original planned highway from Interstate
75 near Cartersville across to Interstate 85 near the Mall of
Georgia in Buford.
One proposal tied to this version
would have reportedly limited exits to five major highway interchanges
, at the freeways
that 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 traffic away from the highway, while freeing it for
trucks. Opponents said that despite the toll, the road would have
encouraged additional development and congestion, creating the
continued urban sprawl
that, at times,
threatens to overwhelm areas much closer to Atlanta-proper.
The highway was to have been officially designated Georgia
state route 500
. Although officially denied by the
, it may also have carried an internal
. Advocates of the highway touted
its use by long-distance truck drivers to have them completely
avoid the congestion of the highways much closer to Atlanta.
The original Perimeter, I-285, which was originally planned as a
of the city and was completed in 1969,
has in effect become one of the main freeway routes for both local
traffic and traffic passing through the Atlanta area.
Budgetary constraints, political pressure, and public opposition
supposedly killed plans for both incarnations of the road. However,
the Northern Arc resurfaced in February 2007, with suggestions that
it be placed further north, out of the current path of exurban land
