In the U.S. state of Georgia, Interstate 20 (I-20) travels from the Alabama state line to the Savannah River, which the Georgia–South Carolina state line straddles. The highway enters the state near Tallapoosa. It travels through the Atlanta metropolitan area and exits the state in Augusta. The highway also travels through the cities of Douglasville, Covington, and Thomson. I-20 has the unsigned state highway designation of State Route 402 (SR 402).

Route description

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

I-20 enters the Peach State near Tallapoosa and after traveling through Western Georgia, it enters the Atlanta metropolitan area. On clear days, eastbound motorists get their first view of downtown Atlanta as they crest the top of Six Flags Hill. The Six Flags Over Georgia amusement park is easily visible off exit 46 eastbound. In Atlanta, the highway travels through the heart of the city, crossing I-75/I-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 I-20 are named for various people and reasons:

History

I-20 eastbound at I-520 interchange. Flyover ramp under construction for I-20 westbound to I-520 eastbound
Although the designation does not appear on shields, Georgia DOT refers to the highway as SR 402

Within Georgia, the first segment of I-20 opened between Downtown Atlanta to Conyers, Georgia. The last part of the highway opened in 1977 or 1978 between Alabama state line to Villa Rica, Georgia[9][10]

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.[11][12][13]

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