In the US state of Georgia, Interstate 20 (I-20) travels from the Alabama state line to the Savannah River, which is the South Carolina state line. 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 Bremen, Douglasville, Conyers, Covington, and Madison. I-20 has the unsigned state highway designation of State Route 402 (SR 402).

Route description

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

I-20 is the main east–west Interstate in Georgia. It is four lanes wide in much of the state.[4] In the Atlanta metropolitan area, the highway ranges from six lanes wide in the most outlying counties to 10 lanes wide in downtown Atlanta.[4] As with all Interstate Highways, all of I-20 in Georgia is included as part of the National Highway System, a system of routes determined to be the most important for the nation's economy, mobility, and defense.[5][6][7]

Named sections

Several stretches of I-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.[8][9]
  • Between both the west and east sides of I-285, I-20 was named the Ralph David Abernathy Freeway in 1991 after the late civil rights activist.[10]
  • From I-285 in Dekalb County to US 129/US 441/SR 24 in the southern part of 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.[11]
  • From US 129/US 441/SR 24 to the South Carolina state line, I-20 is named the Carl Sanders Highway after the former Georgia governor who was born in Augusta.[12]

History

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

I-20's path through Atlanta was designed in the late 1950s, during the era of segregation.[13] The first segment opened between 1960 and 1963 from downtown Atlanta to Conyers.[3][14] It was under construction from just south of Douglasville to downtown Atlanta, from Conyers to a point south of Social Circle, and from Evans to Augusta.[3] By 1966, the highway was proposed from the Alabama state line to SR 5 in Douglasville, was open from Douglasville to the western part of Atlanta, under construction in the western part of Atlanta, was open from downtown Atlanta to US 278/SR 12 near Social Circle, was under construction from that point to SR 83 in Madison; proposed from Madison to the Warren–McDuffie county line, under construction from there to the South Carolina state line.[3][15] Later that year, I-20 was open from Douglasville to the Social Circle area and from SR 383 on the Evans–Martinez city line to the South Carolina state line.[15][16] In 1967, it was under construction from the Social Circle area to Siloam. It was open from US 221/SR 47 south of Appling to the South Carolina state line.[16][17] In 1968, it was open from Douglasville to Madison and from just north of Thomson to the South Carolina state line.[17][18] In 1969, the highway was open from Douglasville to US 129/US 441/SR 24 in Madison.[18][19] In 1970, it was under construction from Madison to the Thomson area.[19][20] In 1971, I-20 was open from Douglasville to SR 44 in Greensboro.[20][21] In 1972, the highway was open from Douglasville to the South Carolina state line.[21][22] In 1973, it was under construction from US 27/SR 1 in Bremen to Douglasville.[22][23] In 1974, it was under construction from the Alabama state line to Douglasville.[23][24] In 1975, it was open from Villa Rica to Douglasville.[24][25] The last part of I-20 opened in 1977 between the Alabama state line and Villa Rica.[26][27]

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.[28][29][30]

From a period of late 2014 to mid-2015, GDOT proposed to widen I-20 from the Alabama state line eastward to Villa Rica, GA. Most of that length had the roadway widened from four to six lanes, with ultimate plans to widen to at least six lanes from Birmingham, Alabama, to Atlanta. In 2015, the widening project begin. Phase 1, which detailed resurfacing the roadway for future expansion preparation, has been completed in 2021. Phase 2 is being prepared to add the additional third lane on I-20 from the Alabama state line to the Villa Rica interchange which is I-20 exit 24.

On April 17, 2017, an abandoned gas pipeline exploded under I-20.[31]

Future

I-285 interchanges

I-20 West approaching the I-285 interchange on the west side of Atlanta

Outside of the west side of Atlanta, this project calls for improvements of the interchange and addition of lanes along I-20 in Cobb, Douglas, and Fulton counties. Additional work includes construction of collector–distributor (CD) lanes and the modification or replacements of bridges along I-20. This project, once completed, will provide more efficient traffic flow through the interchange. This project focuses on reconstructing the interchange to remove left hand exits and improve design speed, and modification and/or replacement of existing bridges and ramps, construction of an I-20 westbound CD system from the interchange to Fulton Industrial Boulevard (FIB), construction of lanes and improvements along eight miles (13 km) of I-20 in both directions from Thornton Road to Hamilton E. Holmes Drive, modification and/or replacement of bridges along I-20, including bridges over CSX Railroad and the Chattahoochee River and finally, the addition of new lanes and improvements along two miles (3.2 km) of I-285 southbound from Hollowell Parkway to Martin Luther King Jr. Drive.[32] The Georgia State Transportation Board on August 15, 2024, awarded the bid for this project to Legacy Infrastructure Contractors for approximately $1.25 billion with construction expected to begin in 2025 and completion expected in 2030.[33]

I-20 East approaching the I-285 interchange on the east side of Atlanta

Outside of the east side of Atlanta, this project will improve traffic flow and safety at this busy interchange. This critical junction in DeKalb County requires operational and geometric improvements to address inefficient flow of traffic and safety performance. This project focuses on reconstructing I-285/I-20 East Interchange ramps with more direct alignments and additional lanes where warranted, constructing new CD road along westbound I-20 and an additional lane in the eastbound I-20 CD road between the I-285/I-20 East Interchange and Wesley Chapel Road, adding auxiliary lanes along I-20 and I-285, replacing the Miller Road and Fairington Road bridges over I-20, and the I-20 bridge over Snapfinger Creek, widening the I-285 northbound bridge over Snapfinger Road and finally, constructing new noise barriers where feasible and reasonable per the preliminary noise impact assessment.[34] Construction on this project began in 2023 with expected completion in 2026.[35]

Express lanes

GDOT proposed to add express lanes known as HOT lanes on I-20 at the outer western and eastern side of Atlanta where the two interchanges of I-285 are located. Part of the plan of I-20 and I-285 interchange project is to make the bridges crossing above I-20 and I-285 to be built with higher height, so the HOT lanes can easily fit on I-20 and I-285 in the future right after the interchange project is complete. The construction will happen right after the I-285 interchange project at the western and eastern side of Atlanta is complete. Of course in the western side of Atlanta, the HOV lanes on I-20 needs to be extended westward from an interchange of I-75 and I-85 to an interchange of I-285 right before construction, so the HOV lanes can directly connect to the HOT lanes on I-20 at the outer western and eastern side of Atlanta where the two interchanges of I-285 are located.[36][37]

Widening projects

From a period of late 2014 to mid-2015, GDOT proposed to widen I-20 from the Alabama state line eastward to Villa Rica. Most of that length had the roadway widened from four to six lanes, with ultimate plans to widen to at least six lanes from Birmingham to Atlanta. In 2015, the widening project began. Phase 1, which detailed resurfacing the roadway for future expansion preparation, has been completed in 2021. Phase 2 is being prepared to add the additional third lane on I-20 from the Alabama state line to the Villa Rica interchange (exit 24).

Another project represents the first bistate agreement between GDOT and SCDOT for a design–build project. This design–build project is for the widening of I-20 with an additional lane in each direction. The widening begins just west of SR 104 interchange (I-20 GA exit 200) and it will terminate at South Carolina Highway 230 (SC 230) interchange (I-20 SC exit 1). The project will widen 1.8 miles (2.9 km) of I-20, replace four bridges over the Augusta Canal and Savannah River, and make intersection improvements at the West Martintown Road interchange in South Carolina. This project will cost $72 million and is scheduled to be completed in 2022.[38]

Interstate 520 (I-520) is a 23.34-mile-long (37.56 km) auxiliary route from Augusta, Georgia, to North Augusta, South Carolina. Approximately 15.62 miles (25.14 km) of the highway is in Georgia. It is also known as the Bobby Jones Expressway in Georgia and the Palmetto Parkway in South Carolina. The Georgia part of the highway has an unsigned designation of State Route 415 (SR 415). Despite its odd first number, both of its endpoints are at I-20 (albeit in two different states), as it loops around the Augusta–North Augusta area to the south.

Interstate 420 (I-420) was an auxiliary Interstate Highway that was planned to bypass south of Atlanta. It is now known as Arthur B. Langford Jr. Parkway. If built, it would have had the unsigned designation State Route 414 (SR 414). It was not built because of opposition from communities in its path.
