Interstate 22 (I-22) is an Interstate highway that, upon completion, will follow the U.S. Route 78 (US 78) corridor on a 213-mile-long (343 km) route from Memphis, Tennessee, to Birmingham, Alabama.[3] I-22 will connect I-240, I-40, I-55, and I-69 (indirectly) in the northwest with I-65 and (indirectly) I-20/I-59 in the southeast. Hence, I-22 will help form a freeway to connect downtown Atlanta with Birmingham, Memphis, Little Rock, Fort Smith, and Oklahoma City.

Along its way through the two states, I-22 will also serve the towns of Jasper, Winfield, and Hamilton, Alabama and Fulton, Tupelo, New Albany, and Holly Springs, Mississippi. Major portions of this highway have either been built new or converted to Interstate Highway standards as of early 2011. According to the American Association of State Highway and Transportation Officials (AASHTO), a connection to another Interstate highway must be completed before this highway is officially designated as part of the Interstate Highway System.[4][5] As of 2013 an interchange with I-65 near Birmingham is under construction. An interchange to be constructed near Byhalia designated as I-269 would be the western terminus of I-22. The portion of I-269 just north of this area was completed by early 2013.


The part of I-22 just east of Fulton, Mississippi, was approved by Congress as "Corridor X" in 1978, as a part of the Appalachian Development Highway System, and parts of I-22 have been under construction ever since.[6] 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.[7]

The one missing part of I-22 is only 2.5 miles (4.0 km) long in Jefferson County, which runs from Coalburg Road near Fultondale to U.S. Highway 31 (US 31) on the northern edge of Birmingham.[8] This short section consists mostly of the major highway interchange with I-65 and US 31.[8]

Future I-22 now covers nearly the full distance between Birmingham and suburban Memphis, stopping short of its lone major interchange in Alabama at I-65.[8] Government funding for the two remaining sections of I-22 has been a priority for Senator Richard Shelby, who served as the Chairman of the Senate's Transportation Subcommittee.[6] In Mississippi, I-22 runs from the Alabama state line across the state to I-269, the future Memphis outer beltway, near Byhalia. This is about twelve miles (19 km) short of the Memphis city limits. While I-22 itself will not continue past I-269 to Memphis, some theorize that an I-22 spur route may be named along the existing US 78 from I-269 northward to the Tennessee state line, creating a better connection between Memphis and I-22.

In 2004, Corridor X was designated as Future I-22 by Public Law Number 108-199,[9] and the designation was made official on April 18, 2005.[10] 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.[10]

U.S. Highway 78[edit]

Future I-22 is also called US 78. Nearly all of US 78 today has been moved from its original roadway from Graysville, Alabama, through to Memphis. The fate of US 78 once Corridor X officially becomes I-22 is still undecided. Its original highway between Graysville and Memphis now bears several different state highway designations. From Graysville to Jasper, it is called State Route 5 (SR-5). For a short stretch in western Jasper, it is designated as SR-69, but once it turns south in western Jasper, the highway becomes SR-118. This remains its designation as until it reaches Winfield, where it becomes US 43, and at Guin, US 278 joins the highway. This continues through the town of Hamilton. In Hamilton, the former route of US 78 becomes SR-74 westward to its intersection with I-22 at exit 7. From that exit though the Mississippi state line, the current US 78 and Future I-22 are the same highway. (Here, the new I-22 has been built on top of the old US 78.)

At the Mississippi state line, travelers can look to the north to see the old US 78. This is still used today as a local road, but it is not accessible from Corridor X. At exit 113 on Corridor X, the old highway is accessible via Mississippi Highway 23 (MS 23) just north of Corridor X, and westbound from there it is MS 178.

MS 178 continues into Fulton, Miss. At Fulton, due to the existence of the Tennessee Tombigbee Waterway, the original highway no longer exists just west of downtown Fulton. Then it can be entered again via I-22 at exit 101 as MS 178 again. The old highway (as MS 178) continues to run parallel with and south of I-22 into and past the town of Tupelo where it crosses Corridor X again at exit 81. The original routing remains parallel to and north of Corridor X through Sherman, Blue Springs, New Albany, Myrtle, and Hickory Flat before crossing Corridor X again at exit 48. It now runs parallel to and south of Corridor X through Potts Camp before crossing Corridor X the last time between Potts Camp and Lake Center and then it continues into Holly Springs, Red Banks, Victoria, Byhalia, and finally through Olive Branch. The decision to be made by the three departments of transportation is to whether to decommission US 78 from Birmingham all the way to downtown Memphis; or to redesignate the former US 78 routing once again as US 78; or to have I-22 also designated as US 78 on its entire distance between Birmingham and Metro Memphis. There has been no indication as of January 2011 as to when such a decision might be made.

Approximately 93 miles (150 km) of Future I-22 is open to traffic in Alabama. The completed section of the route between the Mississippi state line and Jasper was opened to traffic on November 22, 2005.[11] 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 U.S. 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 mileposts. A six-mile (9.7 km) segment between Graysville and Brookside was opened in June 2007,[12] and another 20-mile (32 km) section of Future I-22 between Jasper and Graysville was opened in November 2007.[13] A 1.8-mile (2.9 km) segment between Cherry Avenue in Forestdale to a point about 2.5 miles (4.0 km) short of I-65 near Fultondale, including an interchange with Coalburg Road, which was opened in December 2009.[8] This has been the last segment of I-22 in Alabama to open for traffic so far. Next comes the connection of I-22 with I-65 and US 31.[8] The Alabama Department of Transportation (ALDOT) also plans to widen Coalburg Road from its interchange with I-22 southward to Daniel Payne Drive (which leads to I-65) in order to allow heavy trucks to use it.[14] No timetable for this project has been announced by ALDOT, however.[14] Signs are now in place on Daniel Payne Drive (westbound) informing truckers that access to I-22 is not allowed from Daniel Payne Drive.

I-22 was to be completed in October 2014, with the 14-bridge stack interchange in Birmingham.[15] Construction to widen I-65 to four lanes in both directions has begun from just south of the upcoming highway interchange southward to the 16th Street interchange in Birmingham. Under the present design, I-22 will terminate at I-65, but the highway will continue a short distance beyond I-65 as a long pair of ramps to US 31.[16] Another associated project is a widening of I-65 from its interchange with I-22 northward to the Walker Chapel Road exit.[17]

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 afterwards. Funding delays postponed these into 2010, however. On March 19, 2010, President Barack Obama signed the HIRE (Hiring Incentives to Restore Employment) 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.[18]

The project is the most expensive highway project ever undertaken in Jefferson County, and it is the highest-priced contract that the Alabama Department of Transportation has ever awarded.[15] On August 21, 2014, ALDOT reported that I-22's interchange with I-65 will not be completed until October 2015.[19]

Various lighting projects have been completed along I-22 since 2008. These include lighting at exits 85, 30, and 14. I-22 is a six-lane highway between exit 63, at Jasper, and the current terminus of the highway at exit 93, at Coalburg Road. A stretch of I-22 between exits 57 and 52 is also six-lane freeway. ALDOT, as of July 2010, has no plans to construct an Alabama Welcome Center for eastbound travelers from Mississippi into Alabama.

Exit 53 is currently an unnamed exit. ALDOT stated that the original intent was for this interchange to serve as SR-102 and connect to the existing SR-102 at Townley. The mileage signs on the interchange bridge facings indicate the route as SR-102 but ALDOT has stated that funds are not currently available to extend SR-102 from I-22 to the intersection of SR-124 and SR-102 at Townley. This unbuilt roadway is approximately five miles (8.0 km) long. As of summer 2011, this exit serves only as a connection to SR-118 (the old US 78) on the northside of I-22 and as a local road serving a few residences on the southside of I-22.

In April 2013, the first actual Interstate 22 shields were deployed in Marion County, Alabama, immediately east of the Mississippi state line. Such signage will extend east at least through Walker County into the outskirts of Birmingham.[20]


Future I-22 in Potts Camp

All of existing US 78 in Mississippi has been upgraded to freeway standards. While it was originally stated that I-22 would continue all of the way to the Tennessee state line, the decision was made to have I-22 terminate at the I-269 interchange near Byhalia. Another theory took I-22 along I-269 to I-55/I-69, but those plans also never materialized. However, I-269 and US 78 from I-269 northward to Memphis will create indirect connections to all Memphis-area interstates.

Because US 78's exits and mile posts in Mississippi currently start at the Tennessee state line, there is a discrepancy between the mile posts of Future I-22 and the exit numbers. When I-22 is officially designated, it is assumed that MDOT will re-number the exits to match I-22's terminus at I-269.

Roadway lighting is in place at the following Mississippi exits: 2 (Olive Branch), 26 and 30 (Holly Springs), 61 (New Albany), 86 (Tupelo), and 104 (Fulton). Roadway lighting is also installed as of August 2010 at exits 73 and 76 (Blue Springs and Sherman) which provide access to the Toyota automotive facility.

Mississippi also has currently one welcome center for westbound travelers approximately two miles (3.2 km) from the Alabama state line.[21] There is also a truck weigh station near Fulton.

Interstate 422[edit]

Main article: Corridor X-1

U.S. Congressman Spencer Bachus announced in The Birmingham News in May 2009 that the proposed Northern Beltline had been numbered as I-422.[22] This Interstate Highway should intersect with I-22 near Graysville, and then continue southwest to connect with Interstate 20/Interstate 59, and also from I-22 eastward to connect with I-59 near Argo.[22]

The plans for this highway call for a short spur from I-22, near mile marker 86, northward to connect with I-422. I-422 would pass over I-22 just west of Graysville without an interchange there. Drivers on I-22 would need to use the spur to transit from I-22 to I-422 under this current plan.
