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-mile (34 km) 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.

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 not yet^[update] signed the extension of the route, although Mississippi has.

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 $248 million in 2024) 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.

This SIU begins at the Kentucky–Tennessee border in Fulton and closely follows US 51 to Dyersburg. The 20-mile (32 km) stretch between Dyersburg and Troy is at Interstate Highway standards—opening with the completion of I-155 west of Dyersburg. An additional 10-mile (16 km) stretch north of Union City to within 1,100 feet (340 m) of the Kentucky border is also a freeway. Thus, the vast majority of the work on SIU 7 will involve bypassing the 15-mile (24 km) 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-mile (6.9 km) section between SR 21 and SR 5 northwest of Union City was awarded to Ford Construction Company of Dyersburg for $33 million (equivalent to $46.8 million in 2024). 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. As of July 2014^[update], 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-mile (3.9 km) 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.
