Interstate 20

Interstate 20 (I‑20) is a major east–west Interstate Highway in the Southern United States. I‑20 runs 1,535 miles (2,470 km) beginning near Kent, Texas, at I-10 to Florence, South Carolina, at I-95.[2] Between Texas and South Carolina, I‑20 runs through northern Louisiana, Mississippi, Alabama, and Georgia. The major cities that I-20 connects to includes (from west to east) Fort Worth, Texas; Dallas, Texas; Shreveport, Louisiana; Jackson, Mississippi; Birmingham, Alabama; Atlanta, Georgia; Augusta, Georgia; and Columbia, South Carolina.

From its terminus at I‑95, the highway continues about 2 miles (3.2 km) eastward into the city of Florence as Business Spur 20.

I-20 in southern Fort Worth

I-20 begins 10 miles (16 km) east of Kent at a fork with I-10. From there, the highway travels east-northeastward through Odessa, Midland, and Abilene before turning eastward towards Dallas/Fort Worth. The La Entrada al Pacifico corridor runs along I-20 between U.S. Route 385 (US 385) and Farm to Market Road 1788 (FM 1788). Between Monahans and I-10, I-20 has an 80 miles per hour (130 km/h) speed limit.

From the highway's opening in the 1960s through 1971, I-20 originally went through the heart of the Metroplex via the Dallas-Fort Worth Turnpike. This old route is now signed I-30 (Dallas-Fort Worth Turnpike), US 80 (former stretch between I-635 and Terrell) and Texas Spur 557 (bypass around Terrell).

In 1977, I-20 was rerouted to go through the southern sections of Fort Worth, Arlington, Grand Prairie, Dallas, and Mesquite before rejoining its original route at Terrell. Part of I-20 in Dallas is named the Lyndon B. Johnson Freeway and used to be signed as I-635.

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


In Louisiana, I-20 roughly parallels U.S. Route 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 I-49 near downtown Shreveport and passing close to Barksdale Air Force Base in Bossier City.

From that area, the highway traverses mainly rural, hilly terrain, bypassing Minden, Ruston and Grambling before reaching Monroe.

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

Upon entering Mississippi by crossing the Mississippi River, I-20 immediately enters Vicksburg. Between Edwards and Clinton, the highway mostly follows the original two-lane routing of US 80. In Jackson, I-20 sees a short concurrency with both I-55 and US 49. Also in Jackson is an unusually expansive stack interchange, at the junction of I-20, I-55 North and US 49 South. The interchange replaces a former directional interchange at I-55 North and a cloverleaf at Highway 49. From the Stack, I-20 continues eastward to Meridian, where it begins the nearly 160-mile (260 km) overlap with I-59.

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


I-20 (co-signed with I-59) approaching I-65 in downtown Birmingham. This is sometimes referred to as Malfunction Junction.

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

Also in Birmingham, the intersection of I-20 / I-59 and I-65 is known as a Malfunction Junction because of the interchange's somewhat-confusing design, and the number of traffic accidents that occur there. This section of the Interstate is currently (2018) undergoing construction to reconfigure the interchanges.[3][4]

I-20 enters Georgia 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 46 eastbound. The highway then passes through the center of Atlanta, meeting with I-75 and I-85, which share a common expressway (the "Downtown Connector"). It continues through Metropolitan Atlanta eastward and through the eastern half of Georgia until it exits the state, crossing the Savannah River at Augusta.

Throughout the state, I-20 is conjoined with unsigned State Route 402 (SR 402). Also, I-20 from the Alabama state line to 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 to US 441 in Madison, Georgia, and it is called the Carl Sanders Highway from US 441 to the South Carolina state line.

Upon leaving Augusta, I-20 crosses the Savannah River and enters the Palmetto State and heads northeastward, bypassing Aiken and Lexington before reaching the state capital of Columbia, which can be reached most directly by taking I-26 east at Exit 64 ("Malfunction Junction"), then, almost immediately, I-126 / US 76.

At Columbia, I-20 bypasses the city to the north and again turns northeastward, bypassing Fort Jackson and Camden. After crossing the Wateree River, it turns due east, passes by tiny Bishopville, before reaching the Florence area. It is near Florence where I-20 sees its eastern terminus at Interstate 95. However, for about two miles (3 km), the highway continues into Florence as Business Spur 20.

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 US 401 and I-95 (including the business spur), opened in August 1975.


It was built in 1957 connecting Texas to the east coast running through Shreveport La, Ruston La, and Monroe La making it their first interstate.

Exit numbers of I-20 were changed in Georgia in 2000.[5]


Future plate blue

In 2003, the North Carolina Department of Transportation proposed extending I-20 eastward from Florence to Wilmington at the behest of North Carolina Governor Mike Easley and his 'Strategic Transportation Plan' for the southeast portion of the state.[6][7] The proposed route would follow US 76 east from Florence to Whiteville, North Carolina, then parallel US 74 / US 76 into Wilmington.[8] Part of this route is already designated the future eastern extension of I-74. As part of the 2005 SAFETEA-LU transportation legislation, North Carolina received $5 million for a feasibility study for this extension.[6] While this extension has considerable support among towns in southeastern North Carolina, the South Carolina DOT has stated that they have no interest in upgrading their portion of US 76 to an interstate. Instead, South Carolina is concentrating their efforts on plans to build I-73 that will terminate near Myrtle Beach. This proposed extension has not been approved by the Federal Highway Administration or the AASHTO, so any construction remains far in the future, but NCDOT maintains the routing in its Strategic Highway Corridors maps.[9]

Auxiliary routes

Two I-420s were planned, but never completed or built. One was to be a bypass around Monroe, Louisiana, but was never built. The other I-420 was planned as a bypass to the south of Downtown Atlanta. Due to anti-freeway sentiments, this I-420 was never completed, and the already-built portion has been signed as SR 154/SR 166, named Langford Parkway (formerly the Lakewood Freeway).

Big Spring Correctional Center

The Big Spring Correctional Center (BSCC) is a privately operated prison located in Big Spring, Howard County, Texas, operated by the GEO Group under contract with the Federal Bureau of Prisons. It houses federal "deportable alien" detainees.

BSCC should not be confused with the federally owned and operated Federal Correctional Institution, Big Spring in the same town, or its satellite camp. BSCC consists of four separate physical locations:

"Airpark", at 1701 Apron Drive, opened 1991, capacity 564, housed in 13 buildings formerly part of the decommissioned Webb Air Force Base

"Cedar Hill", at 3711 Wright Avenue, opened June 1998, capacity 520

"Flightline", at 2001 Rickabaugh Drive, opened Feb 1995, capacity 520

"Interstate", at 1801 W Interstate 20, opened 1989, capacity 417, in a converted 72-room former Ramada Inn

Business routes of Interstate 20 in Texas

All of the business loops within Texas are maintained by the Texas Department of Transportation (TxDOT). Interstate 20 has fifteen business loops in the state, all located in western Texas. Along I-20, TxDOT identifies each business route as Business Interstate 20 followed by an alphabetic suffix. Along Texas Interstates, the alphabetic suffixes on business route names ascend eastward and northward. There are gaps in the alphabetic values to allow for future system expansion. The alphabetic naming suffixes are included as small letters on the bottom of route shields.

I-20 business routes in Texas generally follow the path of the former U.S. Route 80 through the central portions of towns now bypassed by the Interstate route.

Douglasville, Georgia

The city of Douglasville is the county seat of Douglas County, Georgia, United States. As of the 2010 census, the city had a population of 30,961, up from 20,065 in 2000.

Douglasville is located approximately 20 miles (32 km) west of Atlanta and is part of the Atlanta Metro Area. Highway access can be obtained via three interchanges along Interstate 20.

Interstate 20 in Alabama

In Alabama, Interstate 20 (I-20) travels 214.7 miles (345.5 km) through the center of the state. It enters the state from Mississippi near Cuba, and travels northeastward through Tuscaloosa and Birmingham. At Birmingham, I-20 turns eastward and heads through Oxford before crossing the Georgia state line near Lebanon. Other cities on the route include Livingston, Bessemer, and Pell City.

For approximately 130-mile (210 km), more than half its distance, I-20 is concurrent with I-59 from the Mississippi state line to eastern Birmingham near Birmingham–Shuttlesworth International Airport. Mileage and exits on the concurrency are I-59's, although both highways have the same mileage for the Alabama concurrency.

Interstate 20 in Georgia

In the U.S. 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).

Interstate 20 in Louisiana

Interstate 20 (I-20) is a part of the Interstate Highway System that spans 1,539.38 miles (2,477.39 km) from Reeves County, Texas to Florence, South Carolina. Within the state of Louisiana, the highway travels 189.84 miles (305.52 km) from the Texas state line west of Greenwood to the Mississippi River, which it crosses into Vicksburg, Mississippi.

I-20 traverses the northern portion of the state, serving the metropolitan areas of Shreveport–Bossier City and Monroe, as well as the smaller cities of Minden and Ruston. It entirely parallels the older U.S. Highway 80 (US 80) corridor through Louisiana. The route is mirrored by I-10, which traverses the southern portion of the state. The two are connected by I-49, the state's major north–south interstate highway.

Interstate 20 in Mississippi

Interstate 20 (I-20) is a major thoroughfare through central Mississippi, connecting the area with major metropolitan areas, including Dallas, Texas, Atlanta, Georgia and Birmingham, Alabama.

Interstate 20 in South Carolina

Interstate 20 (I-20) is a major thoroughfare cutting across the state of South Carolina, linking the state with important transportation and business hubs to the north, west and south, including Atlanta, Georgia, Charlotte, North Carolina (via I-77), Savannah, Georgia (via I-95) and Washington, D.C. (via I-95).

Interstate 20 in Texas

Interstate 20 in Texas (abbreviated I-20 or IH-20) is a major east–west Interstate Highway in the Southern United States, running east from a junction with Interstate 10 east of Kent, Texas, through the Dallas-Fort Worth Metroplex to the border with Louisiana near Waskom, Texas. The original distance of Interstate 20 was 647 miles (1,041 km) from I-10 to the Louisiana border, reduced to the current distance of 636 miles (1,024 km) with the rerouting of I-20 in the 1980s and 1990s. I-20 is known as the Ronald Reagan Memorial Highway within the Dallas-Fort Worth Metroplex.

Interstate 220 (Mississippi)

Interstate 220 (I-220) in Mississippi is a loop around Jackson that provides an interstate connection for Interstate 55 and Interstate 20. The northern terminus for the route is in the northern suburb of Ridgeland, at Interstate 55 exit 104. The highway was Mississippi's first Three-digit Interstate, complete by 1981.

This route provides a route for traffic going to and from the western side of the city. It also provides an alternate route for those heading from Interstate 55 south to Interstate 20 west and from I-20 east to I-55 north by avoiding downtown Jackson.

The southern terminus for the route is in western Jackson at Interstate 20, exit 41. The route is about 12 miles (19 km) long. Although control cities of North Jackson and West Jackson are used at the southern and northern termini, respectively, no control cities are used along the interior length of the route (including guide signs at interchanges). Secondary signs at the termini direct drivers to use the route as a shortcut to Memphis and Vicksburg.

Interstate 820

Interstate 820 (I-820) is a loop of Interstate 20 in Fort Worth, Texas of approximately 35.17 miles (56.60 km) around the city and some of its suburbs. Exit numbers begin at its intersection with I-20 in southwest Fort Worth, and continue in a clockwise direction around the city until it ends at its intersection with I-20 in southeast Fort Worth. A portion of I-820 in the northeast quadrant is co-signed with State Highway 121 as well as State Highway 183. The northwest segment of the loop is officially designated as the Jim Wright Freeway after former United States House Speaker Jim Wright. However, the name is not commonly used, the colloquial reference by the general public is "Loop 820", or simply just 820.

Northeast Texas

Northeast Texas is a region in the northeast corner of the U.S. state of Texas. It is geographically centered on two metropolitan areas strung along Interstate 20: Tyler in the west and Longview/Marshall to the east. Mount Pleasant, Sulphur Springs, Paris and Texarkana in the north primarily along Interstate 30, Jacksonville and Palestine to the south are also major cities within the region. Most of Northeast Texas is included in the inter-state region of the Arklatex.

Its climate is warmer and wetter than most of Texas and its geography is more hilly and forested. Its culture is similar to that of Southeast Texas, but does not have as much of a Cajun influence. Many of the largest cities in Northeast Texas still follow a rural Southern way of life, especially in dialect, mannerisms, religion, and cuisine.

Pecanland Mall

Pecanland Mall is an enclosed shopping mall in Monroe, Louisiana. The mall was named Pecanland because the land on which the mall is located was formerly a pecan farm. The mall is on Interstate 20 near U.S. Highway 165, the two major highways in the area.

Pecanland Mall has 6 anchor stores: Belk, Burlington Coat Factory, Dillard's, Dick's Sporting Goods, JCPenney, and Stein Mart. The mall also features a 450-seat food court and 10-screen cinema.

Rylie, Dallas

Rylie is a neighborhood in Dallas, Texas that was formerly an unincorporated community in Dallas County. Rylie is located between Interstate 20 and U.S. Highway 175 along a former Southern Pacific Railroad line, 11 miles (18 km) southeast of Downtown Dallas. Rylie is a part of the Southeast Dallas area.

Texas State Highway Spur 408

Spur 408, officially designated as "Patriot Parkway", is a four-mile (6 km) connecting freeway between Loop 12 and Interstate 20, completely within the city of Dallas, Texas. The road is an integral part of the orbital road around Dallas, in conjunction with Interstate 635, and parts of Loop 12, Interstate 35E, and Interstate 20.

U.S. Route 180

U.S. Route 180 is an east–west United States highway. Like many three-digit routes, US 180 no longer meets its "parent", US 80. US 80 was decommissioned west of Mesquite, Texas, and was replaced in Texas by Interstate 20 and Interstate 10 resulting in U.S. 180 being longer than U.S. 80. The highway's eastern terminus is in Hudson Oaks, Texas (west of Fort Worth, near Weatherford), at an intersection with Interstate 20. Its western terminus is unclear. Signage at an intersection with State Route 64 in Valle, Arizona 40 miles (64 km) northwest of Flagstaff indicates that the route ends at SR 64, which is consistent with the AASHTO U.S. Highway logs. However, many maps continue the US 180 designation to the south rim of the Grand Canyon at Grand Canyon Village. Signage at the SR 64 intersection as late as 2011 indicated that US 180 continues north concurrent with the route. However, no signage along the route exists past this intersection until SR 64 turns east towards Cameron, Arizona. At this intersection, signage makes no mention of US 180 nor is there any mention at the terminus of SR 64 at US 89.


WGAC-FM is a radio station located in Augusta, Georgia. The station is licensed by the Federal Communications Commission (FCC) to the town of Harlem and broadcast on 95.1 FM with an effective radiated power (ERP) of 5.7 kW. It simulcasts a news/talk format with WGAC 580. Its studios are located just two blocks from the Augusta-Richmond County border in unincorporated Columbia County, Georgia and the transmitter is in Grovetown, Georgia at the interchange of Interstate 20 and GA 388.


WJTP is an AM radio station broadcasting on a frequency of 890 kHz with 5,000 watts of power during daytime hours only. The station is licensed to Lithia Springs, Georgia, a suburb of Atlanta. Its signal is transmitted from a facility closer to the city of Atlanta, Georgia as it shares the broadcast towers of WAOK AM 1380 near the western interchange of Interstate 20 and Interstate 285. The station is currently owned by James Su.Because WJTP shares the same frequency as "clear channel" station WLS AM 890 in Chicago, Illinois, this station only broadcasts during the daytime hours.


WWWE (1100 kHz) is a commercial AM radio station licensed to Hapeville, Georgia and serving the Atlanta metro. Owned by Beasley Broadcasting Group, Inc., the station airs an urban adult contemporary/talk/sports radio format, with some hours of the broadcast day being paid brokered programming. WWWE is co-owned with WAEC in Atlanta, Georgia.

WWWE is considered as a Class D station according to the Federal Communications Commission. It broadcasts with 5,000 watts of power during the daytime and 3,800 watts during critical hours, using a non-directional antenna. Because AM 1100 is a clear-channel frequency reserved for Class A WTAM in Cleveland, WWWE must sign-off at night to avoid interference. The transmitter is located off Fayetteville Road Southeast, near Interstate 20 in Atlanta.
