Interstate 69 (I-69) is an Interstate Highway in the United States consisting of disjointed parts with an original continuous segment from Indianapolis, Indiana, northeast to the Canadian border in Port Huron, Michigan, at 355.8 miles. The remaining separated parts are variously completed and posted or unposted parts of a long-distance extension southwest to the Mexican border in Texas. Of this extension – nicknamed the NAFTA Superhighway because it would help trade with Canada and Mexico spurred by the North American Free Trade Agreement – five pieces—a 6.2-mile (10.0 km) section near Corpus Christi, Texas signed as I-69E, two sections totaling 63 miles (101 km) near Houston, Texas, a 42-mile (68 km) section in northwestern Mississippi and in the Memphis, Tennessee area and a 67-mile (108 km) segment near Evansville, Indiana—have been newly built and/or upgraded and signposted as I-69 (see Interstate 69 in Texas, in Mississippi, and in Indiana). A sixth segment of I-69 through Kentucky, 145 miles (233 km) long, utilizing that state's existing parkway system and a section of Interstate 24, was established by federal legislation in 2008, but the Federal Highway Administration did not authorize the parkways to be signposted as I-69 until upgrades of certain sections are complete. A 55-mile (89 km) section of the previously existing Western Kentucky Parkway from Eddyville to Nortonville was approved and signposted in late 2011. This brings the total length to 589 miles.
The proposed extension evolved from the combination of Corridors 18 and 20 of the National Highway System as designated in the Intermodal Surface Transportation Efficiency Act of 1991, but the federally recognized corridor also includes connecting and existing infrastructure, including Interstate 94 between Chicago and Port Huron and several spurs from I-69. Among these proposed spurs are an extension of Interstate 530 from Pine Bluff, Arkansas (known as "the Dickey Split," for its champion, congressman Jay Dickey), an upgrade of U.S. Route 59 from Texarkana, Texas, and a split in southern Texas to serve three border crossings at Laredo, Pharr, and Brownsville.
In August 2007, I-69 was selected by the USDOT as one of six Corridors of the Future, making it eligible for additional federal funding (which has since been withheld causing some states to suspend construction indefinitely) and streamlined planning and review.

I-69 currently exists as a number of distinct SIUs (Sections of Independent Utility):
- The original (with later additions), fully completed route from Indianapolis, Indiana, to the Blue Water Bridge at Port Huron, Michigan (SIU 1);
- Portions of the Indianapolis beltway (I-465), though not currently signed as such (SIU 2);
- A 67-mile (108 km) section from I-64/I-164 north of Evansville, Indiana to US 231 near the Crane Naval Surface Warfare Center, sections 1-3 of (SIU 3);
- An 18-mile (29 km) section of Interstate 164 near Evansville, Indiana, though not currently signed as such (SIU 4);
- The upgraded portions of the Kentucky Parkway system: Pennyrile, Western Kentucky and Purchase parkways (SIU 5) and (SIU 6);
- A 42-mile (68 km) section from Tunica Resorts, Mississippi, to the I-40/I-69/State Route 300 (SR 300) interchange in Memphis, Tennessee part of (SIU 9) and (SIU 10);
- The existing US 59 freeway from Rosenberg, Texas, to Cleveland, Texas (SIU 19);
- A six-mile (9.7 km) segment of US 77 between I-37 and State Highway 44 (SH 44) near Corpus Christi, Texas (SIU 22) designated as I-69E on May 30, 2013
- A 13.5-mile (21.7 km) section of US 281 between Edinburg, Texas and Pharr, Texas, designated as I-69C on May 30, 2013
- A 53-mile (85 km) section of US-77 from the Veterans International Bridge at Brownsville, Texas to Raymondville, Texas, designated as I-69E on May 30, 2013 (SIU 23).
The original portion of Interstate 69 in Indiana (SIU 1 of the overall national plan) starts at an interchange with Interstate 465, the beltway around Indianapolis on the northeast side of that city. I-69 heads northeast to near Anderson, where it turns more easterly to provide indirect access to Muncie before turning more northerly towards Marion, and Fort Wayne. In Fort Wayne, I-69 runs along the western edge of the city while I-69's only current signed auxiliary route, I-469, loops east of the city. After crossing the Indiana East-West Toll Road (I-80/I-90) near Angola and Fremont, I-69 enters Michigan just south of Kinderhook.
I-69 in Michigan runs north passing through Coldwater and Marshall. There it crosses I-94 east of Battle Creek. Near Olivet, I-69 begins to turn in a northeasterly direction passing through the Lansing metropolitan area. Here I-69 is cosigned with I-96 as an overlap west of Lansing, the only such palindromic pairing in the Interstate Highway System. Where it splits from I-96, I-69 turns east, both in compass direction and in signed direction, and heads north of Lansing and through Flint (where it crosses I-75) to a junction with I-94 just outside Port Huron. At its eastern terminus, I-69 joins I-94 to the Blue Water Bridge across the St. Clair River, where traffic continues on Highway 402 in the Canadian province of Ontario to London, Ontario.
The new section of Interstate 69 in southern Indiana presently begins at the I-64/I-164/SR 57 interchange north of Evansville, at the boundary between the SIU 3 and SIU 4; from there, it runs north to SR 68. Construction was completed on November 19, 2012 on a 67-mile (108 km) segment (SIU 3, Section 1-3). This extension takes the route north-northeast from there to SR 64 near Oakland City, then north-northeast to US 50/US 150 at Washington and finally northeast to US 231 near the Crane Naval Surface Warfare Center. Construction is currently underway for the final new terrain segment (SIU 3, Section 4), which will take I-69 from Crane NSWC northeast to SR 37 on the southwest side of Bloomington and is scheduled to be completed by the end of 2014. From there the existing SR 37 expressway corridor, including Sections 5 (Bloomington to Martinsville) and 6 (Martinsville to Indianapolis) of I-69's SIU 3, will eventually be upgraded to full Interstate Highway standards all the way north-northeast to I-465 on the southwest side of Indianapolis.
The new I-69 in Mississippi and Tennessee starts at an at-grade intersection with the former route of Mississippi Highway 304 (MS 304) in Banks, Tunica County, Mississippi. It continues roughly north-northeast, crossing into DeSoto County, to a partial interchange with the current route of MS 304, then runs easterly to an interchange with I-55 in northern Hernando. It then continues north, overlapping I-55 to the Tennessee state line, and continues northward concurrently with I-55 to the south side of Memphis. It then follows I-240 northward through downtown before joining I-40. Presently, the northern end of this section of I-69 is at the I-40/I-69/SR 300 interchange on the north side of Memphis. This portion of the route was the first "section of independent utility" (SIU) of the proposed extension to be signed as part of the national I-69 route, and the first portion designed as part of the extension.
As of 2013[update], SIU 1 (all of original I-69 north of Indianapolis) and SIU 2 (which will likely use I-465 around Indianapolis, but is as yet unsigned) are open, as is the short SIU 10 in northwestern Mississippi, and part of SIU 9 in the Memphis, Tennessee area. SIUs 5 and 6 in Kentucky are built as freeways, but not yet up to Interstate standards in all areas. On June 6, 2008, President George W. Bush signed HR 1195, designating these parkways as I-69. Kentucky officials planned to place I-69 signs on the Pennyrile Parkway, Western Kentucky Parkway and Purchase Parkway in 2008, but the Federal Highway Administration (FHWA) has not yet given Kentucky approval to do so for the entire route.
Two mainline SIUs are under construction; SIU 3 in Indiana (using $700 million from the 2006 Major Moves deal) and SIU 9 in Tennessee; also a small part of one mainline SIU in Arkansas (Monticello bypass). Portions of these SIUs are open to traffic. Most of the remaining parts of the mainline are in the environmental impact statement (EIS) stages; FHWA has signed records of decision approving the final EIS for SIUs 11, 12, and 13.
While federal legislation established a mandate to extend I-69 from Indiana to Texas, it did not provide funding for its construction. I-69 construction must compete against other projects for traditional funding. Despite approval of several segments, work has been completed on only a few scattered segments, due in part to increasing costs for construction materials and machinery. As a result, several states have indicated that construction of I-69 may not be possible without the use of tolls as the primary means to finance building the highway. Tennessee, Arkansas, and Mississippi passed legislation authorizing toll roads within each state. Indiana examined building most of SIU 3 as a toll road, but quickly reverted to making it toll-free in 2006 with an announcement to that effect by Indiana Governor Mitch Daniels after widespread opposition from I-69 opponents and supporters alike. Due to a lack of funding to build I-69, Tennessee and Mississippi have suspended work on the highway indefinitely for sections outside of the Memphis metropolitan area. Arkansas has halted work on its mainline portion of I-69, aside from the Monticello Bypass. A spur known as the I-530 connector is however under construction. Louisiana officials have stated that that state's current priority is completing Interstate 49, and it will focus on constructing its portion of I-69 after it finishes work on I-49. In contrast to that, Texas, Kentucky and Indiana continue to actively pursue completing their portions of I-69 with or without federal funding.
In Texas, I-69 planning has become part of the Trans-Texas Corridor (TTC) studies. This part of the TTC, called I-69/TTC, includes I-69 and all of its spurs authorized by Congress. It will extend from three border crossings, at Laredo, Pharr, and Brownsville, along US 59, US 281, and US 77 towards Victoria. After the three branches join, I-69 will continue along the general US 59 corridor through Houston to Tenaha, where it will turn easterly to Louisiana along US 84. In metro Houston, I-69 will follow the US 59 freeway corridor through town. A planned branch continues north on US 59 from Tenaha to Texarkana. Most of the proposed I-69 route in Texas already exists as four-lane highways, with a lengthy freeway section stretching north and south of Houston along US 59 and shorter freeway sections of US 77, US 83, and US 281 in the Rio Grande Valley.
The I-69/TTC project has been split into 15 SIUs, which match the original ones but do not share numbers. SIUs 1 to 8 (original 16 to 23) cover the mainline along the "Interstate 69 East" branch to the Mexican border at Brownsville. The "Interstate 69 Central" branch to Pharr is SIUs 9, 11, and 12 (original 24 to 26). The "Interstate 369" and "Interstate 69 West" branches to Texarkana and Laredo are SIUs 13 and 14 (original 29 and 30), and two connections to Brownsville and Pharr are SIUs 10 and 15 (original 31 and 32). The I-69/TTC study also includes SIU L-CC, a connection between Freer and Corpus Christi that was not in the 2000 study. The Texas Department of Transportation (TxDOT) originally considered building the I-69/TTC over new terrain paralleling US 59, US 77, and US 281.
Responding to widespread opposition from environmental groups and property rights activists, TxDOT announced in June 2008 that it will complete I-69 by upgrading the existing US 59, US 77, and US 281 roadways to Interstate standards through rural areas, with bypasses around urban centers along the route. Instead of building the Trans-Texas Corridor as originally planned, TxDOT now plans to finance upgrading the existing highways to I-69 through private sector investment. Under the proposed arrangement, I-69 would remain toll-free where it overlaps pre-existing highways, while bypasses of cities may be tolled. The private firms awarded contracts for I-69 would also build and operate toll roads throughout the state; some of those revenues would then be applied to I-69 construction.
A stated goal of TxDOT's I-69 initiative is that "existing suitable freeway sections of the proposed system be designated as I-69 as soon as possible." In response to TxDOT's request, a six-mile (9.7 km) segment of US 77 between I-37 and State Highway 44 (SH 44) near Corpus Christi was approved for "I-69" designation by FHWA in August 2011, and was approved by the American Association of State Highway and Transportation Officials (AASHTO) in October 2011; signage was posted at an official ceremony on December 5, 2011; it will be re-signed as I-69E as of May 29, 2013.
At the May 18, 2012, meeting of AASHTO, 35 miles (56 km) of US 59 from I-610 in Houston to Fostoria Road in Liberty County were also approved as ready for I-69 signage.
On May 29, 2013, the Texas Transportation Commission gave approval to naming completed Interstate-standard segments of US 77 and US 281 as I-69. US 77 through Cameron and Willacy counties will be signed as I-69E, including 52 miles (84 km) of existing freeway starting at the Rio Grande in Brownsville and running north past Raymondville. The 13 miles (21 km) of US 281 freeway in Pharr and Edinburg will be signed as I-69C.
Louisiana, Arkansas, and Mississippi
As well as covering the part in Texas northeast of Nacogdoches, SIU 16 also extends into Louisiana, ending at US 171 near Stonewall. SIU 15 continues around the south and east sides of the Shreveport area, crossing I-49 and ending at I-20 near Haughton. SIU 14 extends northeast from I-20 to US 82 near El Dorado, Arkansas, and SIU 13 continues northeast to US 65 near McGehee, mainly paralleling US 278. Also included in Corridor 18, as SIU 28, is an extension of I-530 from Pine Bluff south along the US 425 corridor to I-69 west of Monticello; a short piece at the south end opened in mid-2006 as Highway 530. The Charles W. Dean Bridge, SIU 12, will cross the Mississippi River between McGehee, Arkansas and Benoit, Mississippi, while SIU 11 will parallel US 61 to Tunica Resorts. SIU 10, the first completed portion of the I-69 extension, runs east from Robinsonville to I-55 near Hernando, and opened in late 2006. With the record of decision signed in 2007, the FHWA authorized MDOT to add I-69 signs on I-55 from the I-55/I-69 interchange in Hernando to the Tennessee state line.
Tennessee, Kentucky, and Southern Indiana
I-69 SIU 9 overlaps I-55 into Memphis, Tennessee, switching there to I-240 and then I-40 before leaving onto the short State Route 300 (SR 300) connection and then paralleling US 51 to near Millington. On January 18, 2008, FHWA authorized the Tennessee Department of Transportation (TDOT) to erect I-69 signs on I-55, I-240, and I-40 from the Mississippi state line to the I-40/SR 300 interchange. The proposed Interstate 269 will bypass this part of I-69, beginning where I-69 joins I-55 in Mississippi and ending near Millington, and will include the northern part of SR 385 near Millington. SIU 8 will continue beyond Millington, near US 51, to I-155 near Dyersburg, while SIU 7 will use the existing US 51 freeway and new bypasses to the state line at Fulton, Kentucky. TDOT Commissioner John Schroer plans for SIU 7 to be gradually completed over the next 10 years. It is unclear if I-69 through Tennessee will ever be completed, as the state has suspended work indefinitely on SIU 8 due to a lack of funding.
In Kentucky, I-69 mostly follows existing freeways originally built as toll roads. SIU 6 follows the Julian M. Carroll Purchase Parkway (originally called just the Purchase Parkway) and I-24 from Fulton to Eddyville, while SIU 5 continues along the Wendell H. Ford Western Kentucky Parkway (originally called just the Western Kentucky Parkway) and the Edward T. Breathitt Pennyrile Parkway (originally called just the Pennyrile Parkway) to Henderson. While these parkways received the I-69 designation by federal legislation signed in 2008, they will require upgrading to meet Interstate standards—but will not need as much work as in other states, where entirely new highways must be built. The interchanges, designed for tollgates (where all ramp traffic must stop), must be replaced. Kentucky and Indiana plan to finance a new bridge across the Ohio River with tolls. The preferred alternative for SIU 4 will leave the Edward T. Breathitt Pennyrile Parkway near its north end and cross the Ohio River to I-164 near Evansville, Indiana, and will then use I-164 to I-64. At the October 18, 2013, AASHTO meeting, an INDOT request for redesignation of 20.70 miles (33.31 km) of I-164 to I-69 between US 41 and I-64 was approved, pending concurrence from the FHWA.
SIU 3, connecting I-69 to I-465 in southern Indianapolis, will roughly parallel State Road 57 (SR 57) and SR 45, and will use an upgraded version of the existing SR 37 from just south of Bloomington to a point just south of Indianapolis. The segment from I-69 to Bloomington is currently under construction with a 67-mile (108 km) stretch from Evansville to the Crane Naval Surface Warfare Center completed on November 19, 2012. Completion of the entire Evansville to Bloomington segment is expected by 2014. Finally, it has long been assumed that SIU 2 will most likely follow I-465 around the city, though INDOT has never officially confirmed that. The location of an interchange with either I-70 or I-465 has not yet been determined.
On August 31, 2011, Kentucky Governor Steve Beshear announced an agreement between the state and FHWA which will allow the Kentucky Transportation Cabinet to erect I-69 signage along the new Interstate's 17-mile (27 km) overlap with I-24 and the 38-mile (61 km) stretch of the Wendell H. Ford Western Kentucky Parkway between I-24 and the Edward T. Breathitt Pennyrile Parkway. Signage is expected to be placed in the fall of 2011, with construction on necessary upgrades of the portion of the Wendell H. Ford Western Kentucky Parkway expected to be bid in September. On October 25. 2011, I-69 was officially designated by Governor Steve Beshear along the Wendell H. Ford Western Kentucky Parkway along a 55-mile (89 km) stretch between Eddyville and Nortonville. Signage and mile markers were replaced on the 38-mile (61 km) stretch of the Wendell H. Ford Western Kentucky Parkway in mid-December 2012.
A route from Indianapolis northeast via Fort Wayne to I-80/I-90 near Angola was added to the proposed "Interregional Highway System" by the early 1940s. Unlike most of the routes, it was not drawn along an existing U.S. Highway corridor, except north of Fort Wayne (where it used US 27); most of it ran roughly parallel to SR 9 and SR 37. The extension beyond Angola to I-94 near Marshall, Michigan, actually started out as part of what evolved into I-94. On early plans, the Chicago–Detroit route would have replaced US 112 (now US 12), splitting from I-80/I-90 at South Bend. By 1947, the route had been shifted north to present I-94, along what was then US 12, but the connection to South Bend remained, splitting at Kalamazoo.
The I-69 designation was assigned to the Indianapolis–Angola route in 1957, while the short South Bend–Kalamazoo route became proposed Interstate 67. The I-67 designation was shifted east to the US 27 corridor by early 1958, eventually being absorbed into the extension of I-69 to I-94 near Marshall which was built in 1967. The Federal-Aid Highway Act of 1968 authorized an additional 1,500 miles (2,400 km) of Interstates, to be chosen by FHWA; among Michigan's proposals was a 156-mile (251 km) extension of I-69 northeast and east via US 27 to Lansing, M-78 to Flint, and M-21 to Port Huron. However, the FHWA initially only approved the route to I-475 in Flint. The continuation to Port Huron was eventually approved in February 1987. Michigan's 1,241-mile (1,997 km) portion of the Interstate system was completed in 1992, when the last piece of I-69 opened southwest of Lansing between I-96 and Charlotte.
The Intermodal Surface Transportation Efficiency Act of 1991 included two High Priority Corridors that would later become parts of a proposed cross-country extension of I-69:
- (18) Corridor from Indianapolis, Indiana, to Memphis, Tennessee, via Evansville, Indiana.
- (20) US 59 Corridor from Laredo, Texas, through Houston, to the vicinity of Texarkana, Texas.
Corridor 18 was extended southwest to Houston, where it connected to Corridor 20, by the Department of Transportation and Related Agencies Appropriations Act, 1993; the new definition read "Corridor from Indianapolis, Indiana, through Evansville, Indiana, Memphis, Tennessee, Shreveport/Bossier, Louisiana, and to Houston, Texas." The National Highway System Designation Act of 1995 made further amendments to the description of Corridor 18, specifying that it would serve Mississippi and Arkansas, extending it south to the Mexican border in the Lower Rio Grande Valley, and adding a short connection at Brownsville, Texas. This act also specified that Corridors 18 and 20 were "future parts of the Interstate System", to become actual Interstates when built to Interstate standards and connected to other Interstates. Although the act designated Corridor 9 as I-99, no number was assigned to Corridors 18 and 20 yet.
The Transportation Equity Act for the 21st Century (TEA-21), enacted in 1998, greatly expanded the definition of Corridor 18 to include the existing I-69, as well as I-94 between Port Huron and Chicago. A connection to Pine Bluff, Arkansas was added, and the extension to the Lower Rio Grande Valley was detailed as splitting into two routes at Victoria, one following US 77 and the other following US 59 and US 281 to the Rio Grande. This act also assigned the I-69 designation to Corridors 18 and 20, with the branches on US 77, US 281, and US 59 to the Rio Grande being "Interstate 69 East", "Interstate 69 Central", and "Interstate 69 West", respectively. With TEA-21, the I-69 extension took shape, and remains today as those segments.
In 2000, Corridors 18 and 20 were split into 32 Sections of Independent Utility (SIUs) as part of the I-69 (Corridor 18) Special Environmental Study. In Texas, it was originally envisioned that private firms will build, operate, then transfer portions of the highway to the state after a specified period of time. Lawmakers in Kentucky once considered a bill that would authorize the re-tolling of three parkways slated to become part of I-69.
Opposition and controversy
The construction of I-69 has angered environmentalists. In particular, the portion of the route in Indiana would run through wetlands, existing farmland, and forested areas, and cut through geologically sensitive karst topography, which environmentalists argue threatens to pollute underground water systems and harm the rare species that live there. Fiscal conservatives also oppose completion of I-69, arguing that federal legislation establishing the I-69 corridor amounts to an unfunded mandate imposed by the federal government upon the states through which the highway will travel, as the legislation requires states to pursue construction of their portions of I-69, but provides no funding mechanism to cover its estimated $25 billion cost, thereby leaving cash-strapped states to figure out how to finance its construction.
