[1] 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.
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.
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.
[9] The first construction contract was set for SIU 7 on October 30, 2009, covering Section 4 (middle leg of the Union City Bypass).
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.
[11] 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.
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.
[1] 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.
From that interchange, I-69 continues south, merged with I-55 for approximately 12 miles (19 km), 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.
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.
