'''Interstate&nbsp;22''' ('''I-22''') is a {{convert|202.22|mi|km|adj=mid|-long}} [[Interstate Highway System|Interstate Highway]] in the US states of [[Mississippi]] and [[Alabama]], connecting [[Interstate 269|I-269]] near [[Byhalia, Mississippi]], to [[Interstate 65|I-65]] near [[Birmingham, Alabama]]. I-22 is also '''Corridor&nbsp;X''' of the [[Appalachian Development Highway System]] (ADHS). Designated in 2012, I-22 follows the route of older [[U.S. Route 78]] (US&nbsp;78) and is concurrent with the route for all but its eastern most {{Convert|11|mi|km}}. The freeway mainly spans rural areas and passes numerous small towns along its route, including [[Fulton, Mississippi|Fulton]], [[Tupelo, Mississippi|Tupelo]], [[New Albany, Mississippi|New Albany]], and [[Holly Springs, Mississippi|Holly Springs]] in Mississippi and [[Jasper, Alabama|Jasper]], [[Winfield, Alabama|Winfield]], and [[Hamilton, Alabama|Hamilton]] in Alabama.

I-22 was upgraded to [[Interstate Highway standards]] to close a gap in the Interstate Highway System, allowing for more direct connections between cities in the southeast with cities in the central part of the country. I-22 indirectly connects [[Interstate 240 (Tennessee)|I-240]], [[Interstate 40|I-40]], [[Interstate 55|I-55]], and [[Interstate 69|I-69]] in the [[Memphis metropolitan area]] via US&nbsp;78 and [[Interstate 269|I-269]], and indirectly connects with [[Interstate 459|I-459]], [[Interstate 20|I-20]], and [[Interstate 59|I-59]] in the [[Birmingham metropolitan area, Alabama|Birmingham metropolitan area]] via [[Interstate 65|I-65]].

I-22 serves as a connection between Birmingham and suburban Memphis, filling in a gap in the [[Interstate Highway System]]. It also fills a gap that provides freeway passage between [[Atlanta]] and [[Oklahoma City]].<ref>{{cite web |title = Alabama Engineering Hall of Fame |url = https://engrhof.org/members/interstate-22-corridor-x/ |website = engrhof.org |access-date = March 18, 2023 }}</ref> It begins at an interchange with [[Interstate 269|I-269]] at [[Byhalia, Mississippi]], approximately {{convert|25|mi|km}} from downtown [[Memphis, Tennessee|Memphis]] and travels southeast across northern [[Mississippi]] and [[Alabama]], before ending at an interchange with [[Interstate 65 in Alabama|I-65]] approximately {{convert|5|mi|km|spell=in}} north of downtown [[Birmingham, Alabama]].{{cn|date=November 2024}}

===Mississippi===
[[File:Interstate 22 eastbound at Potts Camp, Mississippi.jpg|thumb|Eastbound I-22/US&nbsp;78 in [[Potts Camp, Mississippi]]]]
I-22 begins at a [[cloverleaf interchange]] with [[Interstate 269|I-269]] just west of [[Byhalia, Mississippi|Byhalia]] in [[DeSoto County, Mississippi|DeSoto County]] in northwestern [[Mississippi]] in the [[Memphis metropolitan area|far southeastern suburbs of Memphis]]. It is concurrent with [[U.S. Route 78 in Mississippi|US&nbsp;78]], which is a four-lane freeway through its entire length in Mississippi and the exit numbers for its overlap with I-22 remain based on its mileage. I-22/US&nbsp;78 then continues southeastward into [[Marshall County, Mississippi|Marshall County]] parallel to [[Mississippi Highway 178]] (MS&nbsp;178; the former alignment of US&nbsp;78) with latter route providing local access to small towns along the route. The first major community the freeway passes is [[Holly Springs, Mississippi|Holly Springs]], the county seat of Marshall County. I-22/US&nbsp;78 bypasses the city to the southwest; exits&nbsp;26 (Landfill Road) and 30 ([[Mississippi Highway 4|MS&nbsp;4]]/[[Mississippi Highway 7|MS&nbsp;7]]) provide access to the city. Continuing southeastward, the freeway than passes through the [[Holly Springs National Forest]] and into [[Benton County, Mississippi|Benton County]] passing near several small towns that are accessible through interchanges with or connecting to MS&nbsp;178. Upon exiting the forest into [[Union County, Mississippi|Union County]], I-22/US&nbsp;78 approaches the county seat of [[New Albany, Mississippi|New Albany]] before passing just southwest of it with four exits (60, 61, 63, and 64) providing direct access to the city. [[Mississippi Highway 30|MS&nbsp;30]] shares a brief concurrency with I-22/US&nbsp;78 between exits&nbsp;61 and 64 with the latter exit being at [[Mississippi Highway 15|MS&nbsp;15]]. To the southeast of the city near the town of [[Sherman, Mississippi|Sherman]] in [[Pontotoc County, Mississippi|Pontotoc County]], I-22/US&nbsp;78 has a second brief concurrency with [[Mississippi Highway 9|MS&nbsp;9]] starting between the exits&nbsp;73 and 76. Exit&nbsp;73 is a six-ramp [[partial cloverleaf interchange]], the first non-diamond interchange on the freeway since its starting point at I-269, a distance of about {{convert|61.2|mi|km}}. I-22/US&nbsp;78 then enters [[Lee County, Mississippi|Lee County]] and passes north of [[Tupelo, Mississippi|Tupelo]], its county seat, with five exits (81, 82, 85, 86, and 87) connecting to the city, including an interchange with MS&nbsp;178 (exit&nbsp;81) northwest of Tupelo along with interchanges with the [[Natchez Trace Parkway]] (exit&nbsp;85) and [[U.S. Route 45|US&nbsp;45]]/[[Appalachian Development Highway System#Corridor V|Corridor&nbsp;V]] (exit&nbsp;86) north of the city with Corridor&nbsp;V becoming concurrent with I-22/US&nbsp;78. The freeway then turns eastward and has an interchange with [[Mississippi Highway 371|MS&nbsp;371]] north of [[Mooreville, Mississippi|Mooreville]] before crossing into [[Itawamba County, Mississippi|Itawamba County]]. I-22/US&nbsp;78/Corridor&nbsp;V then has an interchange with MS 178 (to [[Mississippi Highway 363|MS 363]]) in [[Peppertown, Mississippi|Peppertown]] before crossing the [[Tennessee–Tombigbee Waterway]] to its next interchange with South Adams Street (exit 104), which provides access to the community of [[Fulton, Mississippi|Fulton]], the county seat. [[Mississippi Highway 25|MS&nbsp;25]] becomes concurrent with I-22/US&nbsp;78/Corridor&nbsp;V and heads eastward along the route at the exit as well. A weigh station is also just beyond the exit. One exit later (108), MS&nbsp;25 and Corridor&nbsp;V branch off and head northward. I-22/US&nbsp;78 then turns east-southeastward with one final interchange (exit&nbsp;113) with [[Mississippi Highway 23|MS&nbsp;23]] south of [[Tremont, Mississippi|Tremont]] before crossing into [[Alabama]].{{cn|date=November 2024}}

===Alabama===
[[File:Corridor X shields along future Interstate 22 in Alabama.jpg|thumb|upright|Corridor&nbsp;X [[Appalachian Development Highway System|ADHS]] shields in [[Marion County, Alabama]], prior to its redesignation as I-22]]
Still a four-lane freeway, I-22/[[U.S. Route 78 in Alabama|US&nbsp;78]] (internally designated as [[Alabama State Route 4|State Route&nbsp;4]], or SR&nbsp;4) enters into northwestern [[Alabama]] northwest of [[Bexar, Alabama|Bexar]] in [[Marion County, Alabama|Marion County]] and heads east-southeastward. Its first interchange (exit&nbsp;3) is located just east of town at County Route&nbsp;33 (CR&nbsp;33). I-22/US&nbsp;78/SR&nbsp;4's next four exits (7, 11, 14, and 16) serve the city of [[Hamilton, Alabama|Hamilton]], the county seat. The freeway curls around the southwest side of the city. Exit&nbsp;7 gives I-22/US&nbsp;78/SR&nbsp;4 access to [[Alabama State Route 19|SR&nbsp;19]] and [[Alabama State Route 74|SR&nbsp;74]], exit&nbsp;11 is an interchange with [[Alabama State Route 17|SR&nbsp;17]] and exit&nbsp;16 is an interchange with [[U.S. Route 43|US&nbsp;43]]/[[U.S. Route 278|US&nbsp;278]]/[[Alabama State Route 171|SR&nbsp;171]]. The final exit also provides access to the community of [[Guin, Alabama|Guin]]. I-22/US&nbsp;78 then passes south of [[Brilliant, Alabama|Brilliant]] which is accessible by interchanges with [[Alabama State Route 44|SR&nbsp;44]] (exit&nbsp;26, which also serves the town of [[Twin, Alabama|Twin]] and the city of Guin) and [[Alabama State Route 129|SR&nbsp;129]] (exit&nbsp;30, which also serves the community of [[Winfield, Alabama|Winfield]]). An interchange with [[Alabama State Route 233|SR&nbsp;233]] (exit&nbsp;34) serves the community of [[Glen Allen, Alabama|Glen Allen]] before I-22/US&nbsp;78/SR&nbsp;4 crosses into [[Walker County, Alabama|Walker County]]. Its next interchange, [[Alabama State Route 13|SR&nbsp;13]] (exit&nbsp;39), serves the communities of [[Eldridge, Alabama|Eldridge]] and [[Natural Bridge, Alabama|Natural Bridge]]. [[Carbon Hill, Alabama|Carbon Hill]] is served by CR&nbsp;11 (exit&nbsp;46, which also serves [[Nauvoo, Alabama|Nauvoo]]) and [[Alabama State Route 118|SR&nbsp;118]] (exit&nbsp;52; former [[U.S. Route 78 Alternate (Carbon Hill–Jasper, Alabama)|US&nbsp;78 Alternate]]). I-22/US&nbsp;78/SR&nbsp;4 then widens to six lanes and has an unsigned interchange (exit&nbsp;53) with future [[Alabama State Route 102|SR&nbsp;102]]. I-22/US&nbsp;78/SR&nbsp;4 then passes just south of [[Jasper, Alabama|Jasper]], the county seat, which is served by four exits (57, 61, 63, and 65) with SR&nbsp;118, [[Alabama State Route 69|SR&nbsp;69]], [[Alabama State Route 269|SR&nbsp;269]], and Industrial Parkway. The freeway narrows to four lanes at exit&nbsp;57 but expands back to six lanes at exit&nbsp;63. The next three exits (70, 72, and 78) serve [[Cordova, Alabama|Cordova]], [[Parrish, Alabama|Parrish]], [[Dora, Alabama|Dora]], [[Sumiton, Alabama|Sumiton]], [[Wyatt, Alabama|Wyatt]], and [[Quinton, Alabama|Quinton]]. I-22/US&nbsp;78/SR&nbsp;4 then enters [[Jefferson County, Alabama|Jefferson County]] and has an interchange with CR&nbsp;45 (exit&nbsp;81), which serves [[West Jefferson, Alabama|West Jefferson]]. Its next interchange is with [[Alabama State Route 5|SR&nbsp;5]] (exit&nbsp;85); the exit marks the end of the concurrency with US&nbsp;78/SR&nbsp;4 which branches off and becomes concurrent with SR&nbsp;5 south, which serves as a local road for [[Graysville, Alabama|Graysville]] and the [[Birmingham metropolitan area, Alabama|northwestern suburbs of Birmingham]]. Between exits&nbsp;85 and 87 (CR&nbsp;112) is the future site of the interchange with [[Interstate 222|I-222]] (exit&nbsp;86), which would connect I-22 to the proposed [[Interstate 422|I-422]] (Corridor&nbsp;X-1/Birmingham Northern Beltline). I-22 than passes through [[Coalburg, Alabama|Coalburg]] before ending at an interchange with [[Interstate 65 in Alabama|I-65]] (unsigned exits&nbsp;95A and 95B) approximately {{convert|5|mi|km|spell=in}} north of downtown Birmingham. Ramp stubs for an additional interchange (future exit&nbsp;95C) just beyond I-65 to [[U.S. Route 31 in Alabama|US&nbsp;31]] have been made, but construction on this won't begin until at least 2030.<ref name="Projects">[https://cpmsapps.dot.state.al.us/OfficeEngineer/ProjectReports/RuralRpts/Rural37.pdf Project reports] state.al.us</ref>

==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&nbsp;years.<ref name="lynch">{{cite web |url = http://www.businessalabama.com/Business-Alabama/October-2015/Lynchpin-I-22-Nears-Completion/ |title = Lynchpin I-22 Nears Completion |date = October 2015 |work = Business Alabama |access-date = February 20, 2016 |archive-date = July 3, 2018 |archive-url = https://web.archive.org/web/20180703133249/http://www.businessalabama.com/Business-Alabama/October-2015/Lynchpin-I-22-Nears-Completion/ |url-status = dead }}</ref> 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]], and end at [[Interstate 240 (Tennessee)|I-240]] and [[Interstate 69|I-69]]. 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 [[Interstate 55|I-55]], but those plans never materialized.

The part of I-22 just east of [[Fulton, Mississippi]], was approved by [[United States Congress|Congress]] as "Corridor&nbsp;X" in 1978, as a part of the [[Appalachian Development Highway System|ADHS]], and parts of I-22 have been under construction ever since.<ref name="December 22, 2003">{{cite news |title = Shelby's Clout Has Helped Put Corridor X on the Brink of Completion |first = Jeffery |last = McMurray |publisher = Associated Press State and Local Wire |date = December 22, 2003 }}</ref> Corridor X was also designated as "High Priority Corridor&nbsp;10" in the federal [[National Highway System Designation Act]] of 1995 and as "High Priority Corridor&nbsp;45" in later legislation.{{cn|date=November 2024}} Over the many years of development, the project changed multiple times.

In 2004, Corridor&nbsp;X was designated as Future I-22 by Public Law Number&nbsp;108-199,<ref name="January 28, 2004">{{cite news |title = Corridor X Gets Official Seal as I-22 |first = Ginny |last = MacDonald |newspaper = The Birmingham News |date = January 28, 2004 }}{{page needed|date=February 2016}}</ref> and the designation was made official on April 18, 2005.<ref name="April 15, 2005">{{cite news |title = Corridor X Becomes I-22: Signs Bearing Name to Be Unveiled Monday in Jasper by Officials |first = Ginny |last = MacDonald |newspaper = [[The Birmingham News]] |date = April 15, 2005 |page = 1C }}</ref> 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.<ref name="April 15, 2005"/>

The first major completed section of the route between the Mississippi state line and [[Jasper, Alabama|Jasper]] was opened to traffic on November 22, 2005.<ref name="November 23, 2005">{{cite news |title = Corridor X Section Opens in West Alabama |first = Kent |last = Faulk |newspaper = The Birmingham News |date = November 23, 2005 |page = 4C }}</ref> 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.

A {{convert|6|mi|km|adj=on|spell=in}} segment between Graysville and Brookside was opened in June 2007,<ref name="June 2, 2007">{{cite news |title = 13&nbsp;Miles of Corridor X to Open: End of Long Road in Sight for I-22 |first = Ginny |last = MacDonald |newspaper = The Birmingham News |date = June 2, 2007 |page = 1A }}</ref> and another {{convert|20|mi|km|adj=on}} section of Future I-22 between Jasper and [[Graysville, Alabama|Graysville]] was opened in November 2007.<ref name="October 31, 2007">{{cite news |title = 26&nbsp;Miles of Corridor X to Open Nov. 14: Stretch Offers Straight Shot from Forestdale to Memphis |first = Ginny |last = MacDonald |newspaper = The Birmingham News |date = October 31, 2007 |page = 1A }}</ref> A {{convert|1.8|mi|adj=on}} segment between Cherry Avenue in [[Forestdale, Alabama|Forestdale]] to a point about {{convert|2.5|mi|km}} short of I-65 near Fultondale, including an interchange with Coalburg Road, was opened in December 2009.<ref name="December 10, 2009">{{cite news |title = Corridor X Opens New Section: Interchange Lags |last = Staff Reporters |newspaper = The Birmingham News |date = December 10, 2009 |page = 2A }}</ref> Next came the connection of I-22 with I-65 and US&nbsp;31.<ref name="December 10, 2009"/> The [[Alabama Department of Transportation]] (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.<ref>{{cite news |url = http://www.al.com/news/birmingham/index.ssf/2015/05/coalburg_looks_nice_and_smooth.html#incart_related_stories |title = Coalburg Road Looks Nice and Smooth, but Not Done ...

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 [[U.S. Route 31|US&nbsp;31]], with the construction to begin shortly afterward. Funding delays postponed these into 2010, however. On March 19, 2010, President [[Barack Obama]] 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&nbsp;million (equivalent to ${{Formatprice|{{inflation|US-GDP|168600000|2010}}}} in {{Inflation/year|index=US-GDP}}{{Inflation/fn|index=US-GDP}}).<ref name="June 16, 2010">{{cite news |title = Construction Contract Awarded for Final Link of Corridor X |first = Jeremy |last = Gray |newspaper = The Birmingham News |date = June 16, 2010 |url = http://blog.al.com/spotnews/2010/06/construction_contract_awarded.html |access-date = June 21, 2010 }}</ref> The project is the most expensive highway project ever undertaken in Jefferson County, and it is the highest-priced contract awarded by the ALDOT {{As of|2010|lc=y}}.<ref name="July 26, 2010">{{cite news |title = Birmingham I-65/Corridor X Project Set to Launch August 1 |first = Jeremy |last = Gray |newspaper = The Birmingham News |date = July 26, 2010 |url = http://blog.al.com/spotnews/2010/07/birmingham_i-65corridor_x_proj.html |access-date = July 26, 2010 }}</ref>

On November 12, 2012, ALDOT's application for establishing I-22 was conditionally approved by the [[American Association of State Highway and Transportation Officials]] (AASHTO) at a special committee, pending for the [[Mississippi Department of Transportation]] (MDOT) to submit their own application for I-22 and [[Federal Highway Administration]] (FHWA) approval. This therefore officially established the existence of I-22.<ref>{{AASHTO minutes|year=2012A|page=2|link=yes|access-date=September 23, 2014}}</ref>

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, Alabama|Walker County]] into the outskirts of Birmingham.<ref>{{cite news |url = http://www.mountaineagle.com/view/full_story/22151613/article-Interstate-22-signs-going-up |title = Interstate 22 Signs Going Up |work = Daily Mountain Eagle |location = Jasper, AL |date = April 4, 2013 |access-date = June 2, 2013 |archive-date = May 14, 2013 |archive-url = https://web.archive.org/web/20130514233602/http://mountaineagle.com/view/full_story/22151613/article-Interstate-22-signs-going-up |url-status = dead }}</ref> On August 21, 2014, ALDOT reported that I-22's interchange with I-65 would not be completed until October 2015.<ref>{{cite news |url = http://www.bizjournals.com/birmingham/news/2014/08/21/i-22-interchange-with-i-65-wont-be-completed-until.html |title = Interstate 22 Progress: I-65 Interchange with Corridor X Won't Be Completed Until at Least 2015 |date = August 22, 2014 |work = Birmingham Business Journal |access-date = September 25, 2014 }}</ref> The interchange's connections via exit&nbsp;95 to I-65 and the continuation under I-65 as exit&nbsp;95C at US&nbsp;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&nbsp;years; this was completed when I-269 was opened in December 2017.
