Interstate 69 in Tennessee

Interstate 69 (I-69) is a proposed Interstate Highway that will pass through the western part of the US state of Tennessee, serving the cities of Union City, Dyersburg, and Memphis. Currently, a 21 mi section of already-existing freeway in Memphis has been approved for the I-69 designation (although it has not been signed as such) while another segment near Union City opened on February 21, 2024, under the temporary designation of Tennessee State Route 690. However, state officials have stated that they will not commit to finishing the interstate in their state until they receive more federal funding.

Route description
From Fulton, Kentucky, I-69 is planned to continue to the southwest, replacing and bypassing existing U.S. Route 51, serving Union City, Dyersburg (where it will intersect I-155), Ripley, Covington, Millington, and Memphis. It will pass near Discovery Park in Union City.

On January 18, 2008, the Federal Highway Administration (FHWA) authorized the states of Mississippi and Tennessee to extend I-69 from the I-40/State Route 300 (SR 300) interchange in north Memphis to the I-55/I-69 interchange in Hernando, Mississippi; Tennessee has signed the extension of the route, although Mississippi has.

Planned extension
I-69 in Tennessee has been divided into three segments of independent utility (SIUs).

Tennessee considered legislation that would allow I-69 to be built as a toll road, thereby accelerating its design and construction timetable by several years should such legislation be approved. Tennessee's toll road legislation came as Congress withdrew $171 million (equivalent to $ in ) allocated for Tennessee highway projects, including funds for I-69, in 2007. This federal highway allotment was diverted to fund military operations in Iraq under U.S. Troop Readiness, Veterans' Care, Katrina Recovery, and Iraq Accountability Appropriations Act, 2007.

SIU 7
This SIU begins at the Kentucky–Tennessee border in Fulton and closely follows US 51 to Dyersburg. The 20 mi stretch between Dyersburg and Troy is at Interstate Highway standards—opening with the completion of I-155 west of Dyersburg. An additional 10 mi stretch north of Union City to within 1100 ft of the Kentucky border is also a freeway. Thus, the vast majority of the work on SIU 7 will involve bypassing the 15 mi portion of US 51 between Troy and Union City (where it is currently a four-lane surface arterial with at-grade intersections) and redesigning the US 51/US 45 interchange in South Fulton. The redesign is projected to start construction in 2028. This stretch has been divided into five smaller sections. The first two sections make up the Troy Bypass, while the northern three sections represent the Union City Bypass. Tennessee State Route 690 will be the temporary designation for the Union City bypass until I-69 is completed between the Purchase Parkway and I-155.

The first construction contract was set for SIU 7 on October 30, 2009, covering Section 4 (middle leg of the Union City Bypass). The winning bid for constructing the 4.3 mi section between SR 21 and SR 5 northwest of Union City was awarded to Ford Construction Company of Dyersburg for $33 million (equivalent to $ in ). Construction on this section of the Union City Bypass began in the spring of 2010 and was completed in the summer of 2012. However, it remained closed to traffic until adjacent sections were completed. , land acquisition and utility relocations were underway in all five sections from Troy to Union City. The Tennessee Department of Transportation (TDOT) awarded a construction contract for 2.4 mi Section 3 (southern leg of the Union City Bypass) in March 2016 and planned to let a second contract for Section 5 (northern leg of the Union City Bypass) in December 2016. Work began on Section 3 in June 2016.

There is no current timetable for letting contracts to construct the Troy Bypass (Sections 1 and 2). However, TDOT Commissioner John Schroer estimated in February 2013 that it would take around 10 years to gradually complete work on SIU 7 due to lack of funding.

This situation (and the next one below) regarding funding was solved on May 23, 2017, with the signing of the IMPROVE (Improving Manufacturing, Public Roads and Opportunities for a Vibrant Economy) Act. The legislation raised taxes and fees for drivers and others: $0.06 for regular fuel, $0.10 for diesel fuel, and $0.08 for liquefied and compressed natural gases (a total of $355 million). The state would get $250 million, counties $70 million, and cities $35 million. Most vehicle owners saw their registration fees go up by $5; private and commercial owners had their fees go up by $10, with ride-sharing exempt; and heavy truck operators would pay $20 more. Electric vehicle owners in Tennessee (about 2,500) would pay an additional $100 in registration and renewal fees (since they do not pay fuel taxes); hybrid-electric car owners are exempt from the extra charges. The new money would fund parts of I-69 in the state. The Union City sections (3, 4, and 5) of this segment begin construction in 2017. Paving on the three segments begin in July 2021 and the segment opened to traffic on February 21, 2024 as SR 690. While TDOT has acquired the right-of-way and is finalizing design for the Troy portion (1 and 2), a timeline for construction has not yet been established.

SIU 8
SIU 8 proceeds south from Dyersburg, paralleling US 51 to a planned interchange with SR 385 (I-269) in Millington. To facilitate work on the draft environmental impact statement (EIS) for this segment, TDOT has divided SIU 8 into three smaller segments. In April 2006, TDOT has announced the preferred routing for the northern and southern subsections, favoring an alignment to the west of US 51. Meanwhile, studies are still ongoing for the central section, which include alignments both east and west of the existing US 51. Once TDOT identifies the preferred alignment for the central segment, it is expected that a supplemental draft EIS will be necessary before the final EIS can be prepared.

The routing of I-69 has been criticized by the state Sierra Club chapter for not making use of the existing right-of-way for US 51 and for potentially impacting the Hatchie River, a state-designated scenic river.

TDOT has suspended work indefinitely on segment 8 due to a lack of funding. TDOT has further stated that it does not intend to resume work on the Dyersburg–Millington section until Congress commits federal funding to complete environmental studies, right-of-way acquisition, and construction. However, the revived completion of segment 7 of I-69 in northwestern Tennessee connecting to I-155 and I-55 will provide an unbroken freeway route from that region to Memphis. It will bypass the uncompleted segment 8 by following the west side of the Mississippi River before crossing the river into Memphis and linking to partly finished segment 9. TDOT officials determined "there would be value" in finishing just enough of I-69 to link it to I-55, a major north–south route that runs through Memphis.

SIU 9
South of Millington, I-69 will intersect the I-269 Memphis Outer Beltway, then continue southwest, roughly parallel to US 51, then abruptly turn east near General DeWitt Spain Airport to connect with I-40 at the existing SR 300 interchange in the Frayser neighborhood. I-69 follows I-40 for about 3 mi to the I-40/I-240 Midtown Interchange, where I-69 continues south along the Midtown portion of I-240 (mileposts 25–31) to the I-240/I-55 interchange in Whitehaven. From that interchange, I-69 continues south, merged with I-55 for approximately 12 mi, crossing the Mississippi state line. The Mississippi Department of Transportation (MDOT) has been working on widening I-55/I-69 between Hernando and the Tennessee state line, adding travel lanes in each direction, reconstructing bridges, and improving traffic flow at interchanges. Meanwhile, TDOT is reconstructing I-55 and I-240 from the Mississippi line to Memphis. With much of the route already built and at Interstate standards through Memphis, the FHWA authorized TDOT to sign I-69 over I-55, I-240, and I-40 on January 18, 2008; however, TDOT has done so. However, it is still signed as an "I-69 FUTURE CORRIDOR".

Similar to segment 8, TDOT has suspended work indefinitely on the unbuilt section between SR 300 and the proposed interchange with I-269 near Millington due to a lack of funding. TDOT has further stated that it does not intend to resume work on this section until Congress commits federal funding to complete environmental studies, right-of-way acquisition and construction.

Exit list
This exit lists includes exits from existing I-55, I-240, I-40, SR 300, I-155, and US 51. The I-69 designation has only been approved on the southern 15 mi. I-69 is not currently signed along this route.

Tennessee State Route 690
Tennessee State Route 690 is the designation given to highways currently open that are not yet part of I-69, but will be in the future. The first of these opened on February 21, 2024 around Union City. Planning began on the bypass on October 30, 2009, with construction commencing in the spring of 2010. The central portion of the bypass was completed in the summer of 2012 without mainline paving, however the segments connecting both ends to US 51 on both sides of Union City remained incomplete, until construction on those segments began in 2016, and was completed in early 2024.

It is estimated TN 690 will be extended northward to the Kentucky state line in the future, as the interchange in South Fulton between US 51, US 45W, US 45E, and US 45 is completely rebuilt to allow I-69 mainline traffic to continue into Kentucky on a free-flowing roadway. Construction will commence on the interchange in 2028, but upon completion, the TN 690 designation is expected to be replaced by the I-69 designation, connecting with the eventual segment of Interstate 69 in Kentucky.

Auxiliary routes
There are to be two auxiliary routes of I-69 in Tennessee. The first, I-169 in Martin and Union City, will be a spur route that is currently designated as SR 22. The second, I-269, is a beltway around Memphis. Currently, I-269 is designated south of I-40. The northern segment of SR 385 is expected to be redesignated as I-269 in the future.
