I-20 runs from Texas to South Carolina serving major southern economic hubs such as [[Dallas–Fort Worth]] and [[Atlanta]].<ref name="Google">{{google maps |url=https://maps.google.com/maps?f=d&hl=en&geocode=9823043144323157679,31.094000,-104.049870%3B15883297316566579360,34.193215,-79.844145&saddr=I-20+E+%4031.094000,+-104.049870&daddr=33.498461,-86.903229+to:I-20+E%2FI-20-SPUR+E+%4034.193215,+-79.844145&mra=dpe&mrcr=0&mrsp=1&sz=11&via=1&sll=33.448058,-86.810532&sspn=0.258963,0.461426&ie=UTF8&ll=32.805745,-92.856445&spn=16.660668,29.53125&z=5 |title=Overview map of I‑20 |access-date=2008-02-15}}</ref>

===Texas===
{{main|Interstate 20 in Texas}}

I-20 begins in western [[Reeves County, Texas|Reeves County]] at a fork with I-10. From there, the highway travels east-northeastward through [[Odessa, Texas|Odessa]], [[Midland, Texas|Midland]], and [[Abilene, Texas|Abilene]] before turning eastward toward the [[Dallas–Fort Worth metroplex]]. The [[La Entrada al Pacífico]] corridor runs along I-20 between [[U.S. Route 385|US Route&nbsp;385]] (US&nbsp;385) and [[Farm to Market Road 1788]] (FM&nbsp;1788). Between [[Monahans, Texas|Monahans]] and I-10, I-20 has an {{convert|80|mph|km/h|adj=on}} speed limit.

From the highway's opening in the 1960s through 1977, I-20 originally went through the heart of the metroplex via the [[Dallas–Fort Worth Turnpike]]. This old route is now signed [[Interstate 30|I-30]] (Dallas–Fort Worth Turnpike and from US&nbsp;80/I-30 intersection at Mesquite to [[Downtown Dallas]]), [[U.S. Route 80|US&nbsp;80]] (former stretch between I-635 and [[Terrell, Texas|Terrell]]), and [[Texas State Highway Spur 557|Spur&nbsp;557]] (bypass around Terrell). In 1977, I-20 was rerouted to go through the southern sections of Fort Worth, [[Arlington, Texas|Arlington]], [[Grand Prairie, Texas|Grand Prairie]], [[Dallas]], and [[Mesquite, Texas|Mesquite]]. It split off from the old route initially at I-820 in west Fort Worth the later on at its current junction near [[Aledo, Texas|Aledo]] in [[Parker County, Texas|Parker County]]. It rejoins the old route near Terrell. Part of I-20 in Dallas used to be signed as I-635 and shares the Lyndon B. Johnson Freeway name with the remainder of I-635. Parts on the south side of Fort Worth were originally signed as I-820.<ref>{{Cite map|url=http://dallasfreeways.com/dfwfreeways/old-highway-maps/1973_exxon_dfw_west_large.jpg|title=Dallas–Fort Worth metroplex|publisher=[[Exxon]]}}</ref>

I-20 continues eastward from Terrell, bypassing [[Tyler, Texas|Tyler]], [[Longview, Texas|Longview]], and [[Marshall, Texas|Marshall]] before crossing the Louisiana border near Waskom.

===Louisiana===
{{main|Interstate 20 in Louisiana}}

In [[Louisiana]], I-20 roughly parallels [[U.S. Route 80 in Louisiana|US&nbsp;80]] through the northern part of the state.

Entering the state from near [[Waskom, Texas]], the highway immediately enters the [[Shreveport–Bossier City metropolitan area]], intersecting [[Interstate 49|I-49]] near downtown Shreveport and passing close to [[Barksdale Air Force Base]] in Bossier City.

I-20 traverses mainly rural, hilly terrain, bypassing [[Minden, Louisiana|Minden]], [[Grambling, Louisiana|Grambling]], and [[Ruston, Louisiana|Ruston]] before reaching [[Monroe, Louisiana|Monroe]].

From Monroe, I-20 enters flatter terrain as it approaches the [[Mississippi River]]. Before crossing the Mississippi, the highway passes [[Tallulah, Louisiana|Tallulah]]. At the Mississippi River, I-20 leaves Louisiana and enters [[Vicksburg, Mississippi|Vicksburg]].

===Mississippi===
{{main|Interstate 20 in Mississippi}}

Upon entering Mississippi by crossing the [[Mississippi River]], I-20 immediately enters [[Vicksburg, Mississippi|Vicksburg]]. Between Edwards and [[Clinton, Mississippi|Clinton]], the highway mostly follows the original two-lane routing of [[U.S. Route 80|US&nbsp;80]]. In Jackson, I-20 sees a short concurrency with both [[Interstate 55|I-55]] and [[U.S. Route 49|US&nbsp;49]]. Also in Jackson is an unusually expansive [[stack interchange]], at the [[Interchange (road)|junction]] of I-20, I-55 north, and US&nbsp;49 south. The interchange replaces a former directional interchange at I-55 north and a [[cloverleaf interchange]] at US&nbsp;49. From the stack, I-20 continues eastward to [[Meridian, Mississippi|Meridian]], where it begins the nearly {{convert|160|mi|km|adj=on}} overlap with [[Interstate 59|I-59]].

The route of the Mississippi section of I-20 is defined in Mississippi Code § 65-3-3.

===Alabama===
{{main|Interstate 20 in Alabama}}

I-20 (along with I-59) crosses the Alabama state line near [[York, Alabama|York]], and it stays conjoined as it passes through western Alabama and [[Tuscaloosa, Alabama|Tuscaloosa]]. At [[Birmingham, Alabama|Birmingham]], the two highways pass through downtown together before splitting at exit&nbsp;130 just east of [[Birmingham–Shuttlesworth International Airport]]. I-20 continues eastward through [[Oxford, Alabama|Oxford]]–[[Anniston, Alabama|Anniston]] and the [[Talladega National Forest]], passing by [[Talladega Superspeedway]] in the process, which is visible from the highway.

Also in Birmingham, the intersection of I-20/I-59 and [[Interstate 65|I-65]] was known as a [[Malfunction Junction (disambiguation)|Malfunction Junction]] because of the interchange's somewhat-confusing design, and the number of traffic accidents that occurred there. This section of the Interstate and its interchanges have since been reconfigured.<ref>{{Cite web|url=https://www.al.com/news/birmingham/index.ssf/2017/11/birmingham_malfunction_junctio.html|title = Malfunction Junction: What are those massive columns?|date = 3 November 2017}}</ref><ref>{{Cite web|url=https://www.al.com/news/index.ssf/2018/04/dysfunction_at_malfunction_jun.html|title = What went wrong on Malfunction Junction?

===Georgia===
{{main|Interstate 20 in Georgia}}

I-20 enters Georgia near [[Tallapoosa, Georgia|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 Six Flags Hill. The [[Six Flags Over Georgia]] amusement park is easily visible off exit&nbsp;46 eastbound. The highway then passes through the center of [[Atlanta]], meeting with [[Interstate 75|I-75]] and [[Interstate 85|I-85]], which share a common expressway (the [[Downtown Connector]]). It continues through the Atlanta metropolitan area eastward and through the eastern half of Georgia until it exits the state, crossing the [[Savannah River]] at [[Augusta, Georgia|Augusta]].

Throughout the state, I-20 is conjoined with unsigned [[Georgia State Route 402|State Route&nbsp;402]] (SR&nbsp;402). Also, I-20 from the Alabama state line to [[Interstate 285 (Georgia)|I-285]] in Atlanta is named the "Tom Murphy Freeway", but it is called the "Ralph David Abernathy Freeway" within I-285. The Interstate Highway is also named the Purple Heart Highway from I-285 in [[DeKalb County, Georgia|DeKalb County]] to [[U.S. Route 129|US&nbsp;129]]/[[U.S. Route 441|US&nbsp;441]]/[[Georgia State Route 24|SR&nbsp;24]] in [[Madison, Georgia]], and it is called the Carl Sanders Highway from US&nbsp;129/US&nbsp;441/SR&nbsp;24 to the South Carolina state line.

===South Carolina===
{{main|Interstate 20 in South Carolina}}

Upon leaving Augusta, I-20 crosses the [[Savannah River]] and enters the Palmetto State and heads northeastward, bypassing [[Aiken, South Carolina|Aiken]] and [[Lexington, South Carolina|Lexington]] before reaching the state capital of [[Columbia, South Carolina|Columbia]], which can be reached most directly by taking [[Interstate 26|I-26]] east at exit&nbsp;64 ("Malfunction Junction"), then, almost immediately, [[Interstate 126|I-126]]/[[U.S. Route 76|US&nbsp;76]].

At Columbia, I-20 bypasses the city to the north and again turns northeastward, bypassing [[Fort Jackson (South Carolina)|Fort Jackson]] and [[Camden, South Carolina|Camden]]. After crossing the [[Wateree River]], it turns due east and passes by tiny [[Bishopville, South Carolina|Bishopville]], before reaching the [[Florence, South Carolina|Florence]] area. It is near Florence where I-20 sees its eastern terminus at [[Interstate 95|I-95]]. However, for about {{Convert|2|mi|km|spell=in}}, the highway continues into Florence as [[Interstate 20 Business (Florence, South Carolina)|I-20 Bus.]]

I-20 in the Palmetto State is known as either the J. Strom Thurmond Freeway or John C. West Freeway. The first section to be completed was the [[bridge]] over the Savannah River in 1965; the last, the section between [[U.S. Route 401|US&nbsp;401]] and I-95 (including the business spur), opened in August&nbsp;1975.
