Marshall County parallel to
Mississippi Highway 178 (MS 178; the former alignment of US 78) with latter route providing local access to small towns along the route. The first major community the freeway passes is
Holly Springs, the county seat of Marshall County. I-22/US 78 bypasses the city to the southwest; exits 26 (Landfill Road) and 30 (
MS 4/
MS 7) provide access to the city. Continuing southeastward, the freeway than passes through the
Holly Springs National Forest and into
Benton County passing near several small towns that are accessible through interchanges with or connecting to MS 178. Upon exiting the forest into
Union County, I-22/US 78 approaches the county seat of
New Albany before passing just southwest of it with four exits (60, 61, 63, and 64) providing direct access to the city.

Natchez Trace Parkway (exit 85) and
US 45/
Corridor V (exit 86) north of the city with Corridor V becoming concurrent with I-22/US 78. The freeway then turns eastward and has an interchange with

Tennessee–Tombigbee Waterway to its next interchange with South Adams Street (exit 104), which provides access to the community of
Fulton, the county seat.
MS 25 becomes concurrent with I-22/US 78/Corridor V and heads eastward along the route at the exit as well. A weigh station is also just beyond the exit.

History
The concept of a Memphis-to-Birmingham expressway was discussed as early as the 1950s but did not move beyond talk for more than 20 years.
Political push for Corridor X began in the 1970s under the leadership of Congressman Tom Bevill. After Bevill's retirement, Congressman Robert Aderholt was involved with completing the project.
When studies for I-22 began, the highway was proposed to continue west to downtown
Memphis, Tennessee
Memphis is a city in Shelby County, Tennessee, United States, and its county seat. Situated along the Mississippi River, it had a population of 633,104 at the 2020 United States census, 2020 census, making it the List of municipalities in Tenne ...

. Several other proposals were also considered. One took I-22 along I-269 to I-55/I-69 and another took it along Crump Boulevard to end at
I-55, but those plans never materialized.
The part of I-22 just east of
Fulton, Mississippi, was approved by

as "Corridor X" in 1978, as a part of the
ADHS, and parts of I-22 have been under construction ever since.
Corridor X was also designated as "High Priority Corridor 10" in the federal
National Highway System Designation Act of 1995 and as "High Priority Corridor 45" in later legislation. Over the many years of development, the project changed multiple times.
In 2004, Corridor X was designated as Future I-22 by Public Law Number 108-199,
and the designation was made official on April 18, 2005.
In Alabama and Mississippi, blue signs reading "FUTURE/I-22/CORRIDOR" at left and an I-22 shield with "FUTURE" instead of "INTERSTATE" at the right were unveiled on April 18, 2005.

was opened to traffic on November 22, 2005.
Exits on the Jasper Bypass portion of I-22 were originally numbered using a kilometer-based sequence because, at the time this stretch was opened, it appeared that all highways in the US were going to be measured using the metric system. The final decision was made to remain using miles, and they have been renumbered according to the highway's
milepost

s. A segment between Graysville and Brookside was opened in June 2007,
and another section of Future I-22 between Jasper and
Graysville was opened in November 2007.
A segment between Cherry Avenue in
Forestdale to a point about short of I-65 near Fultondale, including an interchange with Coalburg Road, was opened in December 2009.
Next came the connection of I-22 with I-65 and US 31.
The
Alabama Department of Transportation
The Alabama Department of Transportation (ALDOT) is the government agency responsible for transportation infrastructure in Alabama. The Department is organized into five geographic regions, with a Central Office located in Montgomery, Alabama, ...
(ALDOT) widened Coalburg Road from its interchange with I-22 southward to Daniel Payne Drive (which leads to I-65) to allow heavy trucks to use it; this project was nearly complete as of May 2015. Signs are now in place on Daniel Payne Drive (westbound) informing truckers that access to I-22 is not allowed from Daniel Payne Drive.
ALDOT was to award contracts in August 2009 for the construction of the final segment of I-22, including its large interchange with I-65 and
US 31, with the construction to begin shortly afterward. Funding delays postponed these into 2010, however. On March 19, 2010, President

signed the
Hiring Incentives to Restore Employment Act (HIRE Act) into law, which included an extension of federal highway funding through the end of 2010. This extension gave the ALDOT the opportunity to proceed with its plans for the construction of final segment of I-22 in Alabama. The opening of the bids for this project began on May 21, 2010. ALDOT announced on June 16, 2010, that the project has been awarded to the company Archer Western Contractors for $168.6 million (equivalent to $ in ).
The project is the most expensive highway project ever undertaken in Jefferson County, and it is the highest-priced contract awarded by the ALDOT .
On November 12, 2012, ALDOT's application for establishing I-22 was conditionally approved by the
(AASHTO) at a special committee, pending for the
Mississippi Department of Transportation
The Mississippi Department of Transportation (MDOT) is the organization in charge of developing and maintaining all state and federal roadways in the U.S. state of Mississippi. In addition to highways, the department also has a limited role in s ...

(FHWA) approval. This therefore officially established the existence of I-22.
In April 2013, the first actual I-22 shields were deployed in
Marion County, Alabama, immediately east of the Mississippi state line. Such signs will extend east at least through
Walker County into the outskirts of Birmingham. On August 21, 2014, ALDOT reported that I-22's interchange with I-65 would not be completed until October 2015. The interchange's connections via exit 95 to I-65 and the continuation under I-65 as exit 95C at US 31 remained under construction. In March 2016, the interchange with I-65 and continuation to US 31 was still under construction. New lanes north and southbound were opened on I-65 passing through the interchange and construction and painting operations were carried out on the I-22 entrance and exit ramps. The interchange to I-65 opened to traffic on June 20, 2016, while the connector to US 31 remained under construction.
Mississippi officials announced May 5, 2015, that the state officially began the process to designate its portion as I-22. The two requirements to be able to apply for this designation were to upgrade the route to Interstate standards and to connect to an existing Interstate within 25 years; this was completed when I-269 was opened in December 2017. The I-65 interchange was opened in October 2015. The route was officially signed in Mississippi in a ceremony on October 23, 2015.

Mississippi exit numbers are based on US 78 mileage.

. There will be no exits other than its termini. The highway has been proposed because an
interchange directly between I-22 and I-422 cannot be built due to environmental issues. AASHTO approved the designation on May 18, 2012.
Construction on this new route has not been scheduled at this time.

; on May 18, 2012, it was approved by AASHTO.
Construction on a short section of the route between SR 79 and 75 was started shortly afterwards, but issues with funding and local opposition held up the project. More funding for the interstate was provided in Spring 2023. It covered the construction of I-422 between SR 79 to US 31 for a total of . The construction of this part of the interstate, which will be four lanes, was expected to begin later in the Spring and be completed by 2028, but the completion date was delayed to 2032. A complaint has been filed over construction resuming, and although ALDOT expected to break ground on the resumption of the project in November 2023, no new information was made public for several months. Work finally resumed on the initial phase between SR 75 and SR 79 in late-June 2024, this phase is expected to be completed in 2027.
