Interstate 22


Interstate 22 is the designation for the U.S. 78 / Corridor X freeway (High Priority Corridor 10) between Memphis, Tennessee, and Birmingham, Alabama. I-22 begins where future Interstate 269 crosses paths with U.S. 78 outside Byhalia, Mississippi. Taking a mostly rural route, I-22 runs east southeasterly to Holly Springs and through Holly Springs National Forest before reaching the south side of New Albany. Beyond an older stretch there that was upgraded, Corridor X continues to the Tupelo area, where it crosses paths with the U.S. 45 freeway leading south to Shannon and north to Saltillo.

The remainder of Interstate 22 in Mississippi ventures east over hilly terrain to Fulton and the Alabama state line east of Tremont. Once in Alabama, I-22 passes by Hamilton, Guin and Winfield to Walker County. The freeway doubles as Alabama 4 throughout the Heart of Dixie.

Advancing eastward, I-22 travels north of Eldridge and Carbon Hill through areas of the Appalachian piedmont. The freeway passes between Horseshoe Mountain and Mc Clesky Hill before swinging southeast by Jasper and Cordova. Once near Graysville, U.S. 78 separates from Interstate 22 for an arterial route south to Adamsville, Forestdale and Birmingham while I-22 parallels Fivemile Creek east to Coalburg and Interstate 65 near Lewisburg. A ribbon cutting ceremony took place on June 20, 2016 for the final segment, between Coalburg Road and I-65. Future work will connect the east end with U.S. 31.

The first official Interstate 22 signs were installed in Marion and Walker Counties, Alabama by April 2013. Interstate 22 was formally designated in Mississippi at a signage ceremony held on October 23, 2015 at New Albany.16

High Priority Corridor

Proposed Interstate 22 is part of High Priority Corridor 10: ADHS Corridor X from Memphis to Birmingham. Its designation is written into law. The "Corridor X" designation is a result of its placement within the alphabetical listing of Appalachian Regional Planning Commission highway corridors. Corridor X is the 24th corridor in a listing from A to Z (notwithstanding some derivative routes such as A-1 and O-1).

According to Bill Minor, Mississippi DOT Northern District transportation commissioner, signs would go up as soon as possible labeling U.S. 78 as future Interstate 22 ... and to that end, Future Interstate 22 markers were placed along Mississippi's U.S. 78 in November 2004. On April 18, 2005, signs marking the new route were erected in Jasper, Alabama. Completion of the route was initially expected in 2012, with the major section from Graysville to the Mississippi State Line open by December 2006.5

Parallel U.S. Routes

Interstate 22 parallels or overlays U.S. 78 for its entire duration. It is thought that U.S. 78 will return to its original alignment, parts of which are retained as U.S. 78 Alternate, in Alabama upon completion of I-22. Mississippi may do the same, decommision the US route or retain it as a concurrency with I-22.16


Interstate 22 was officially written into law by H.R. 2673, Section 111(2)(B) of the Consolidated Appropriations Act, 2004. On 1/23/2004, it became Public Law No: 108-199. Interstate 22, along with Interstates 66, 69, 73, 74, and 99, is part of a growing pantheon of Interstate routes whose designation was written into law. Some background on this follows.

In the article, "Wicker: Interstate status for 78 near: Congressman hopes U.S. 78 will become I-22 soon" (03/04/02) from the Northeast Mississippi Daily Journal of Tupelo, Interstate 22 became publicized as a potential number for the first time by a politician.

The Interstate 22 designation was to have been written into law as part of the federal Fiscal Year 2003 Transportation Appropriations Bill, but the Senate did not ratify a measure included in the bill to do this in February 2003. According to the Birmingham News article, "Corridor X transition to Interstate 22 stalled" by Ryan Mahoney (03/07/03), the goal was to install "Future Interstate 22" signs along U.S. 78/Corridor X prior to the completion of the route to attract businesses to locate along the route. This process only delayed the inevitable.

Proposed federal legislation designating Corridor X as Interstate 22 followed. U.S. Rep. Robert Aderholt, R-Haleyville stated that a U.S. House committee approved language in a bill that designated the corridor as Interstate 22. The designation encourages the prospects for industrial recruiting along the freeway and opens the door to potential new highway funds as well. On July 24, 2003, Aderholt inserted language in the House Transportation and Treasury Appropriation bill for fiscal 2004 that applied the Interstate 22 designation. "The interstate occurs when the road is connected on either end to an existing interstate." Additionally it was stated that this bill language allowed for portions that were already completed to Interstate standards to receive official signs proclaiming that they are apart of Future Interstate 22.1 The Interstate 22 designation was also included in the Senate version of the appropriation bill.2

On September 9, 2003, the U.S. House of Representatives passed the Transportation-Treasury Appropriations Act for Fiscal Year 2004, paving the way for the Interstate 22 designation along U.S. 78. Congressman Roger Wicker, R-Tupelo stated, "We actually already have gotten beyond the bigger hurdle, the committee vote," with regards to getting Interstate 22 official. The vote continued to the Senate, where Mississippi Republican senators Thad Cochran and Trent Lott had already supported the measure.3 In November 2003, a House-Senate conference committee approved the Interstate 22 designation for U.S. 78. The 2004 appropriations bill for transportation contained language indicating that once the Corridor X freeway extends to Interstate 65, U.S. 78 can be designated Interstate 22. This ruling cleared the way for the installation of "Future Interstate 22" signs along the corridor.4

Construction Progress - Alabama

Alabama began work on Corridor X / Interstate 22 with initial construction appropriations in 1983; under this schedule, completion of the route would occur nearly 30 years later. Since 2001 eventual Interstate 22 traveled from the Mississippi/Tennessee state line near Memphis east southeastward to Alabama 129 near Winfield (Exit 30). Additionally the Jasper bypass, I-22 between Exits 52 and 65, was also in use. Construction on the 6.5-mile segment between Carbon Hill and Eldridge began in 2001. On November 22, 2005, the Carbon Hill segment opened between Exit 34 (Alabama 233) and Exit 52.

13 more miles of freeway opened between Walker County 81 (Exit 78) and Cherry Avenue (Exit 91) from near Dora to Forestdale by June 9, 2007. This section of highway was opened to local traffic only with a truck restriction to prevent commercial vehicles from using neighborhood streets to connect with the freeway.8 An additional 13 miles of new freeway were slated to open on November 14, 2007 (a ribbon cutting ceremony eventually took place on November 22, 2007) between Jasper (Industrial Parkway [Exit 65]) and Exit 91, bringing future Interstate 22 to within five miles of completion.9

Future Interstate 22 at I-65

Most of the base pavement for the final 2.5 miles of Interstate 22 between Coalburg Road and Interstate 65 was in place. This view looked from an adjacent subdivision at the interchange with Interstate 65. Photo taken October 20, 2012.

The final five mile stretch of Interstate 22 in Alabama linked the new freeway to the Interstate system, with a $145 million interchange proposed at Interstate 65. Associated work included a $73 million widening project for I-65 between 41st Avenue North and 16th Street North near the junction. That work began in 2007 and was followed by additional widening of Interstate 65 from 41st Avenue North to Walker Chapel Road starting in 2009. The work added three-lane collector distributor roadways along a four-mile stretch of Interstate 65. Completion of the Interstate 22 and 65 interchange was estimated for 2010.9, two years earlier than a previously suggested Fall 2012 completion date, but ultimately one year after officials initially thought.7

2.5 miles of freeway, between Cherry Avenue (Exit 91) and Coalburg Road (Exit 93) opened to local traffic on December 9, 2009. Following was a $168.6-million contact let on May 21, 2010 for work commencing July 2010 on the final 2.5 miles of I-22 in Alabama. Construction continued through October 15, 2014, the revised completion date, on the I-22/65 interchange project.10 Delays surrounding the design of one of the bridges pushed back completion of the new interchange to late August 201515, and again until June 2016.

The interchange under construction between Interstates 22 and 65 includes a connection to adjacent U.S. 31.6 Further east, a feasibility study was conducted to extend Corridor X to Interstates 20 & 59 east of Downtown Birmingham.8

Construction Progress - Mississippi

Meanwhile along the Mississippi stretch of Interstate 22, much of the route was completed in the mid-1990s as a freeway. Certain portions of the freeway however were not up to Interstate standards. These included stretches of shoulder less freeway especially near Fulton and west of Tupelo and the curbed median through New Albany. It was thought that approximately $30 million and three years of roadwork including edge draining, fencing, and other work was needed to bring the freeway to Interstate standards. This work was not a part of the original construction; at that time, planners did not feel the U.S. 78 freeway would eventually be considered for inclusion in the Interstate highway system.2

Shoulders were added to the sections between New Albany and Tupelo and from Fulton to the state line by summer 2010. A $30-million project was awarded in September 2010 for a three-year reconstruction of Interstate 22 between Coldwater Road and the West Holly Springs exit.11 A project to upgrade the New Albany interchange was awarded on November 8, 2011 with an expected completion on November 22, 2013.12 Work in Marshall County, which included upgrades to the median, was expected to be completed in November 2012. Rubblization and repaving through Desoto and Marshall Counties continued to June 2013.13 Completion of the needed improvements to I-22 lead to the route being made official in Mississippi by AASHTO on May 15, 2015.

Future Interstate 22 at I-65

The U.S. 78 freeway through New Albany (Exits 63 through 61) and the Tallahatchie River bridge was previously substandard in nature with a narrow curbed median and no barrier to separate traffic. The New Albany bypass was under construction by 1967. Photo taken June 1, 2010.

The ultimate plans, funding and construction of the I-22 western extent was thought to take seven to eight years, with connections to the existing Memphis Interstate network via U.S. 78, U.S. 72, Tennessee 385, or Mississippi 304.2 The end point was eventually narrowed down to I-269, the Memphis outer beltway. This is confirmed with the June 28, 2016 sign plans showing End and Begin shield assemblies planned for the interchange with I-269 [see page 50 of the MDOT document "Section 905 - Proposal"].

Construction for Interstate 269 in Mississippi runs through 2018, which upon completion, will complete the link between I-22 and Interstate 55 and 69 at Hernando, Mississippi.

Western Terminus - Interstate 269 and U.S. 78 - Byhalia, Mississippi
A full cloverleaf interchange with collector distributor roadways along both Interstate 22 and Interstate 269 will join the two freeways in a rural area near Byhalia. This view looks along U.S. 78 east under the four sets of bridges that will eventually carry I-269 and the c/d roadways. Photo taken by Chris Kalina (03/08/14).
Eastern Terminus - Interstate 65 - Birmingham, Alabama
Perspective from Interstate 22 east
Beyond Coalburg Road (Exit 93) Interstate 22 comes to within one mile of its eastern terminus with Interstate 65. This segment opened to traffic June 20, 2016, completing I-22 through Alabama. Photo taken by Chris Patriarca (07/08/16).
Traffic departs for the ramps to I-65 north and south while base-grade pavement continues a short distance ahead to a stub end atop a bluff. The mainline for I-22 will eventually duck under the multilevel directional interchange for a connection to U.S. 31. Flyover ramps in the distance carry motorists from I-22 east to the c/d roadway to I-65 north ahead of the Fultondale off-ramp (Exit 266) and from I-65 north to I-22 west. Photo taken by Chris Patriarca (07/08/16).
Interstate 22 ends as two lanes depart for Interstate 65 north to nearby Fultondale. Huntsville lies in the northern part of the state and is linked to the north-south freeway by Interstate 565. Otherwise drivers bound for I-65 south will bypass downtown Birmingham in five miles just beyond the I-20/59 exchange. Photo taken by Chris Patriarca (07/08/16).
Historical Perspective from Interstate 22 east
The future travel lanes of Interstate 22 ended abruptly on a bluff above Interstate 65. Eventually these dropped quickly below I-65 mainline with a stub end ahead of U.S. 31. A flyover otherwise joins the northbound collector distributor roadway of Interstate 65 ahead of the Fultondale off-ramp (Exit 266) to U.S. 31. Photo taken 10/20/12.
Perspective from Interstate 65 south
Walker Chapel Road (Exit 267) passes overhead on the one mile approach to U.S. 31 to Fultondale and Interstate 22 west to Memphis (Exit 265). A trumpet interchange joins I-65 with U.S. 31 while a multilevel directional interchange connects the Memphis-bound freeway with I-65. Photo taken by Chris Patriarca (07/08/16).
As the mainline of Interstate 65 spans Ellard Road and Fivemile Creek, a collector distributor roadway prepares to depart for U.S. 31 and Interstate 22. The c/d roadway funnels traffic between the two interchanges returning to I-65 ahead of Daniel Payne Drive (Exit 264). Photo taken by Chris Patriarca (07/08/16).
Interstate 65 arcs southwest at the egress point for U.S. 31 (Exit 265B) and Interstate 22 (Exit 265B). The U.S. 31 (Decatur Highway) mainline can be seen in the background as the U.S. highway continues south toward Downtown Birmingham. The final two miles of Interstate 22 opened to traffic June 2016 connecting I-65 and Birmingham with the outer reaches of Memphis, Tennessee. Photo taken by Chris Patriarca (07/08/16).
Exit 265A prepares to leave for Interstate 22 west along the collector distributor roadway as drivers pass through the high speed interchange. Motorists entering from U.S. 31 are directed to continue ahead for Interstate 65 south to Birmingham and Montgomery. The freeway will travel through the state capitol city in 96 miles. Photo taken by Chris Patriarca (07/08/16).
Historical Perspective from Interstate 65 south
Pier supports and some girders were in place for the eventual flyover ramps connecting Interstates 22 and 65. The $168.6-million project interchange includes an 85 foot tall flyover from I-65 north to I-22 west.14 Photo taken 10/20/12.
The Interstate 22 mainline now passes below Interstate 65 in this scene to connect with adjacent U.S. 31 in the future. A separate contract was to focus on construction of 3,000 feet of roadway linking I-22 and U.S. 31. Completion of this element of the project was expected in 2014,14 then in 2015. It ultimately opened to traffic on June 20, 2016. Photo taken 10/20/12.
Perspective from Interstate 65 north
A ramp leaves for Daniel Payne Drive (Exit 264) along Interstate 65 north on the 0.75-mile approach to Interstate 22 west (Exit 265A) to the Memphis area. I-22 spokes on a northwest course from Exit 265A through west central Alabama toward the city of Jasper. The Memphis-bound freeway enters Mississippi to the west of Hamilton. Otherwise I-65 meets U.S. 31 to Fultondale in one mile (Exit 265B). Photo taken by Chris Patriarca (07/08/16).
Traffic departs for Interstate 22 west at a multilevel interchange built between 2010 and 2016. The high speed exchange opened June 2016 with provisions for an eventual extension of I-22 a short distance southeast to U.S. 31 (Decatur Highway). A separate ramp 0.25 miles ahead joins Interstate 65 with U.S. 31 to nearby Fultondale. Photo taken by Chris Patriarca (07/08/16).
Historical Perspective from Interstate 65 north
