In Georgia, Interstate 20 runs from the Alabama border to the Savannah River, which the Georgia-South Carolina border straddles. The highway enters the state near Tallapoosa. It passes through the Atlanta metropolitan area and exits the state near Martinez. The route also passes through the cities of Douglasville, Covington, and Thomson. I-20 has the unsigned state highway designation of State Route 402.

Route description

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:

I-20 eastbound at I-520 interchange. Flyover ramp under construction for I-20 westbound to I-520 eastbound

History

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][10]

Future

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.
