Interstate 285
Encyclopedia
Interstate 285 is an Interstate Highway loop
encircling Atlanta, Georgia
, for 63.98 miles (103 km). I-285 is also known as unsigned State Route 407 and is colloquially referred to as the Perimeter. Suburban sprawl has made it one of the most heavily traveled roadways in the United States, and portions of the highway slow, sometimes to a crawl, during rush hour
. It is also signed as Atlanta Bypass on Interstate 75
and Interstate 85
.
It is estimated that more than two million people use the highway each day. It is by far the busiest interstate in the Atlanta Metropolitan Area.
to I-85 the most heavily traveled. One segment of the highway near Spaghetti Junction
(a large, flyover highway interchange northeast of Atlanta) with Interstate 85
widens to 18 lanes, including collector-distributor lanes. Exits are numbered
clockwise
, starting at the southwestern-most point at I-85, and ending just east of there where it meets I-85 again near Hartsfield-Jackson Airport.
Between I-85 and I-20
in southwest Fulton County
, I-285 is designated as the "Bob A. Holmes Freeway", where I-285 heads north, and has an interchange with the Langford Parkway
. Between I-20 in northwest Atlanta and I-75 near Cumberland Mall
, it is designated as "James E. 'Billy' McKinney Highway" as it continues north, and starts to curve to the east just west of the I-75 interchange.
The northern portion of I-285, east of the "Cobb Cloverleaf
" (I-75 junction) to "Spaghetti Junction
" (I-85 junction), is frequently referred to as the Top End perimeter in traffic reports, especially by Captain Herb Emory (ABC
affiliate WSB-TV
and WSB
AM) and Jason Durden on WSB-FM
. This section, which includes an interchange with Georgia 400 at exit 27 (frequently cited as the most dangerous intersections in Atlanta), is one of the busiest freeways in the United States, handling about 250,000 cars per day and crossing through three counties. Through that stretch, the freeway expands from six or eight lanes to between ten and fourteen lanes.
Much of Atlanta's high-end commercial real estate
has developed along I-285, particularly at the northwestern I-75 and the Georgia 400 junctions. Notable buildings include the 35-story King and Queen towers
in the Perimeter Center
business district and the Cobb Galleria
complex in the Cumberland/Galleria area.
East of the Spaghetti Junction, I-285's direction switches from east to south, as it connects with the Stone Mountain Freeway
at exit 39, and intersects with I-20 at exit 46, where I-285 starts to curve towards the southwest. At exit 52, it intersects with Interstate 675
, and heads straight west after the intersection with I-75 near the Hartsfield-Jackson Atlanta International Airport
.
A portion of the section between I-75 and I-85 on the south side of I-285 has been bridge
d with a new runway
and taxiway
of Hartsfield-Jackson Atlanta International Airport
, the only interstate in the nation to a have an underpass on a runway (underpasses for taxiways do occur elsewhere). Computer animation
s were developed prior to construction to simulate a jumbo jet touching down on the runway from a driver's perspective. The entire highway within the tunnel
s is outfitted with stopped-vehicle
sensors and fire detectors. Two electronic signs on either side of the tunnels can warn drivers if the tunnel is closed in an emergency
. For 1.21 miles (1.95 km) in the southwest corner, I-85 occupies the median
of I-285, yet the roadways remain separate.
Heavy truck
s traveling through (but not into) Atlanta are required to bypass the city on I-285, as there is a well-signed and heavily enforced ban on through truck traffic along I-75, I-85, I-20, Georgia 400, and many other major Atlanta thoroughfares. As with highways just outside I-285, trucks are also prohibited from the far-left one or two lanes (except where there are left exits open to trucks).
The complete circumference of I-285 is covered by Georgia NaviGAtor
, Georgia's intelligent transportation system
(ITS). One hundred fifty-three CCTV video camera
s, twenty-six electronic message signs and traffic

s have been installed in phases between 1999 and 2010 by Georgia DOT. Additionally, ramp meters are present at nearly all entrance ramps onto I-285, with the exception of the southeast section of I-285 and the major freeway-to-freeway connection ramps.
To many residents of Atlanta, the Perimeter defines a useful boundary to separate metro Atlanta's core from its surrounding suburb
s. People distinguish a location as being inside or outside the Perimeter, sometimes abbreviated as ITP and OTP, a recent local neologism. This was also the rough boundary chosen by BellSouth
for separating landline
telephone exchanges in suburban area code 770
from the existing area code 404
in 1995.
The reconstruction of I-285, particularly on the top-end and the Spaghetti Junction reconfiguration (covered by the revive285 project), has cost about $355 million.
Until 2000, the state of Georgia used the sequential interchange numbering system on all of its Interstate Highways. The first exit on each highway would begin with the number "1" and increase numerically with each exit. In 2000, the Georgia Department of Transportation switched to a mileage-based exit system, in which the exit number corresponded to the nearest milepost.
, the plans were dropped from the Regional Transportation Plan, in favor of the expansion of the rural state road network outside of Atlanta. The state still retains ownership of most of the land that would be needed to complete at least the northern section of the Outer Loop, known as the Northern Arc
. , ideas have been considered to build that highway even further north, through areas that are still rural.
The I-285 and Georgia 400 interchange is slated to be reconfigured with collector/distributor roads along Georgia 400 and a complete full stack interchange
that will make it the largest freeway interchange east of Los Angeles
. The new interchange is expected to be able to handle around 300,000 cars per day. Feasibility studies have been completed, and it is in Atlanta's 2025 Regional Transportation Plan.

History
I-285 was opened in 1969 at a cost of $90 million as a four lane highway throughout (two lanes each way).The reconstruction of I-285, particularly on the top-end and the Spaghetti Junction reconfiguration (covered by the revive285 project), has cost about $355 million.
Until 2000, the state of Georgia used the sequential interchange numbering system on all of its Interstate Highways. The first exit on each highway would begin with the number "1" and increase numerically with each exit. In 2000, the Georgia Department of Transportation switched to a mileage-based exit system, in which the exit number corresponded to the nearest milepost.
