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 {{Convert|8|mi|km|spell=in}} 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 {{Convert|2|mi|km|spell=in}} of I-285 southbound from Hollowell Parkway to Martin Luther King Jr. Drive.<ref>{{Cite web|url=https://0013918-gdot.hub.arcgis.com/|title=I-285/I-20 West Interchange}}</ref> 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.<ref>{{Cite web|url=https://0013915-gdot.hub.arcgis.com/|title=I-285/I-20 East Interchange}}</ref> ===Express lanes=== GDOT proposed to add express lanes known as [[High occupancy/toll and express toll lanes|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 [[High-occupancy vehicle lane|HOV lanes]] on I-20 needs to be extended westward from a interchange of I-75 and I-85 to a 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.<ref>{{Cite web|url=http://www.dot.ga.gov/DS/GEL|title=Express Lanes}}</ref><ref>{{Cite web|url=https://www.youtube.com/watch?v=rJ4mNLQLlHw|title=I-285/I-20 East Interchange Project Visualization}}</ref> ===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, Georgia|Villa Rica]].

In 2015, the widening project began. Phase&nbsp;1, which detailed resurfacing the roadway for future expansion preparation, has been completed in 2021. Phase&nbsp;2 is being prepared to add the additional third lane on I-20 from the Alabama state line to the Villa Rica interchange (exit&nbsp;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&nbsp;104 interchange (I-20 GA exit&nbsp;200) and it will terminate at South Carolina Highway&nbsp;230 (SC&nbsp;230) interchange (I-20 SC exit&nbsp;1). The project will widen {{convert|1.8|mi|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&nbsp;million and is scheduled to be completed in 2022.<ref>{{Cite web|url=http://www.dot.ga.gov/BS/Projects/SpecialProjects/I20SavannahRiver|title=I-20 @ Savannah River Bridge Replacements}}</ref> ==Exit list== {{jcttop|state=GA|old|length_ref=}} {{GAint|old |county=Haralson |cspan=4 |location=none |mile=0.00 |road={{jct|state=AL|I|20|dir1=west|city1=Birmingham}} |notes=Continuation into Alabama }} {{jctbridge|old |location=none |type=incomplete |mile=1.32 |bridge=Georgia Visitor Information Center; accessible from eastbound lanes only }} {{GAint|old |location=Tallapoosa |mile=4.67 |old=1 |exit=5 |road={{jct|state=GA|GA|100|city1=Tallapoosa|city2=Bowdon}} }} {{GAint|old |location=none |mile=8.95 |old=2 |exit=9 |road=Waco Road&nbsp;– [[West Georgia Technical College]] }} {{GAint|old |county=Carroll |cspan=4 |location=none |mile=11.11 |old=3 |exit=11 |road={{jct|state=GA|US|27|name1=[[Georgia State Route 1|SR&nbsp;1]]|city1=Bremen|city2=Carrollton|location3=[[University of West Georgia]]}} }} {{jctbridge|old |location=none |type=incomplete |mile=14.99 |bridge=Weigh station; accessible from westbound lanes only }} {{GAint|old |location=Temple |mile=18.70 |old=4 |exit=19 |road={{jct|state=GA|GA|113|city1=Temple}} }} {{GAint|old |location=Villa Rica |mile=23.81 |old=5 |exit=24 |road={{jct|state=GA|SR|61|SR|101|city1=Villa Rica|city2=Dallas}} |notes=Southern terminus of SR 101; former [[U.S. Route 78S in Georgia|US&nbsp;78S]] and [[U.S. Route 78 Alternate (Alabama–Georgia)|US&nbsp;78 Alt.]] }} {{GAint|old |county=Douglas |cspan=8 |location=none |mile=26.05 |old=6 |exit=26 |road=Liberty Road ([[Georgia State Route 8 Connector (Villa Rica)|SR&nbsp;8 Conn.]] north)&nbsp;– [[Villa Rica, Georgia|Villa Rica]] |notes=Southern terminus of SR&nbsp;8 Conn. }} {{GAint|old |location=none |mile=30.00 |old=7 |exit=30 |road=Post Road }} {{GAint|old |location=Douglasville |lspan=3 |mile=34.15 |old=8 |exit=34 |road={{jct|state=GA|SR|5|name1=Bill Arp Road|city1=Douglasville}} }} {{GAint|old |mile=35.62 |old=9 |exit=36 |road=Chapel Hill Road }} {{GAint|old |mile=37.39 |old=10 |exit=37 |road={{jct|state=GA|SR|92|name1=Fairburn Road|city1=Douglasville}} }} {{GAint|old |location1=Douglasville |location2=Lithia Springs |mile=41.26 |old=11 |exit=41 |road=Lee Road&nbsp;– [[Lithia Springs, Georgia|Lithia Springs]] }} {{GAint|old |location=none |mile=43.47 |old= |exit= |bridge=[[Blair Bridge (Georgia)|Blair Bridge]] over [[Sweetwater Creek (Chattahoochee River)|Sweetwater Creek]] }} {{GAint|old |location=Lithia Springs |mile=44.00 |old=12 |exit=44 |road={{jct|state=GA|GA|6|name1=Thornton Road|city1=Austell|city2=Powder Springs|location4=[[Sweetwater Creek State Park]]|location5=[[Camp Creek Parkway]]|location6=[[Hartsfield–Jackson Atlanta International Airport|Atlanta Airport]]|extra=airport}} }} {{GAint|old |county=Cobb |cspan=2 |location=none |mile=46.60 |old=13 |exit=46 |road=Riverside Parkway&nbsp;– [[Six Flags Over Georgia|Six Flags Park]] |notes= Six Flags Drive has been renamed to Riverside Parkway }} {{GAint|old |location=Mableton |mile=47.10 |old=13C |exit=47 |type=incomplete |road=Six Flags Parkway&nbsp;– [[Six Flags Over Georgia|Six Flags Park]] |notes=Westbound exit and eastbound entrance }} {{jctbridge|old |state=GA |county1=Cobb |county2=Fulton |river=[[Chattahoochee River]] |mile=47.84 |bridge=[[Debra Mills Commemorative Bridge]] }} {{GAint|old |county=Fulton |cspan=14 |location=none |mile=48.57 |old=14 |exit=49 |road={{jct|state=GA|SR|70|name1=Fulton Industrial Boulevard|location1=[[Fulton County Airport (Georgia)|Fulton County Airport]]|extra=airport}} }} {{GAint|old |location=Atlanta |lspan=17 |mile=50.57 |old=15 |exit=51 |road={{jct|state=GA|I|285|name1=Atlanta Bypass / [[Georgia State Route 407|SR&nbsp;407]]|location1=[[Montgomery, Alabama|Montgomery]]|city2=Macon|location3=[[Chattanooga, Tennessee|Chattanooga]]|location4=[[Greenville, South Carolina|Greenville]]}} |notes=I-285 exits 10A-B; signed as exits 51A (south) and 51B (north) }} {{GAint|old |mile=52.07 |old=16 |exit=52 |road={{jct|state=GA|SR|280|name1=Hamilton E.
