SR 401 Georgia 402.svg SR 403

In Georgia, Interstate 20 runs from the Alabama border to the Savannah River, which the Georgia-South Carolina border straddles. It passes through the heavily congested Atlanta metropolitan area and exits the state at Augusta. The highway allows Georgians and various cargo to travel to various locations, including Columbia, South Carolina; Birmingham, Alabama; Jackson, Mississippi and Dallas, Texas. I-20 has the unsigned state highway designation of State Route 402.

Route description[edit]

I-20 is four lanes in much of the state. In the Atlanta metro area, the highway ranges from six lanes in the most outlying counties to 10 lanes in downtown Atlanta.

I-20 enters the Peach State near Tallapoosa and after passing through western Georgia, it enters the Atlanta metropolitan area. On clear days, eastbound motorists get their first view of downtown Atlanta as they come over the top of the Six Flags Hill. The Six Flags Over Georgia amusement park is easily visible off exit 47 eastbound. In Atlanta, the highway passes through the heart of the city, crossing Interstate 75 and Interstate 85, which share a common expressway (the "Downtown Connector"). It continues though Metropolitan Atlanta eastward and through the eastern half of Georgia until it exits the state, crossing the Savannah River at Augusta.

Several stretches of Interstate 20 are named for various people and reasons:

  • From the Alabama state line to I-285 on the west side of Atlanta, I-20 is named the Tom Murphy Freeway, after the former speaker of the Georgia House of Representatives.[3][4]
  • Between both the west and east sides of The Perimeter (I-285), I-20 was named the Ralph David Abernathy Freeway in 1991 after the late civil rights activist.[5]
  • From I-285 in Dekalb County to U.S. Route 441 near Madison, I-20 is named the Purple Heart Highway for military veterans who either died or were injured in combat while in service on or after April 15, 1917.[6]
  • Between U.S. 441 and the South Carolina border, I-20 is named the Carl Sanders Highway after the former Georgia governor who was born in Augusta.[7]

Auxiliary routes[edit]

  • I-520.svg Interstate 520, a freeway spur that goes around the western and southern sections of Augusta before crossing into South Carolina.

History[edit]

Although the designation does not appear on shields, Georgia DOT refers to the highway as SR 402

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.[8][9]

Future[edit]

From the Alabama state line to Villa Rica, I-20 is currently being widened from 4 to 6 lanes in ultimate plans to widen to at least six lanes from Birmingham to Atlanta. Some sections are currently under construction.
