The
Tennessee Department of Transportation's (TDOT) plans called for the two sections to be connected in phases. Plans had the portion extending south from an incomplete interchange with SR 385 south to the Mississippi state line to completed in October 2015 to coincide with completion of the section in Mississippi from the Tennessee state line to
Mississippi Highway 302 (MS 302). On January 29, 2007, the
Federal Highway Administration (FHWA) issued a record of decision giving final federal approval for I-269, paving the way for the two states to design and construct the remaining section between Hernando and Collierville. The first section of what is now I-269, the Winfield Dunn Parkway, from I-40 to
US 64 opened on September 4, 2007, signed as SR 385. The segment between US 64 and to
SR 193 (Macon Road) opened on June 15, 2009, and the segment between SR 193 and
SR 57 opened on November 22, 2013. On October 18, 2007, the
Mississippi Department of Transportation (MDOT) announced that a bond was successfully issued through the state's Highway Enhancements Through Local Partnerships (HELP) Program for $83 million (equivalent to $ in ) to cover planning and
right-of-way acquisition costs for Mississippi's portion of the route. Mississippi began its part of I-269 construction on June 23, 2011, with the section from the state line to I-55 totaling construction costs of $640 million (equivalent to $ in ) as of 2014. On October 23, 2015, the first signed segment of I-269 opened between the eastern terminus of SR 385 in Collierville and MS 302. On December 5, 2017, the second segment opened between MS 302 and
MS 305, including the I-22 interchange. In 2018, TDOT redesignated a portion of SR 385 between Collierville and I-40 in Arlington as I-269. The segment of I-269 from the I-55/I-69 interchange in
Hernando to MS 305 in
Lewisburg, Mississippi, was completed on October 26, 2018, completing the connection between I-40 in Tennessee and I-55 in Mississippi. The construction costs of the Tennessee portion of SR 385 from the 1980s until completion in 2013 was over $500 million (equivalent to $ in ). Both states' combined investments were over $1.2 billion (equivalent to $ in ) for the I-269 project, including construction and rights-of-way expense listed above. On October 13, 2021, a new interchange at McIngvale Road opened to traffic following a ribbon-cutting ceremony. The $8.7-million project also included realigning a section of McIngvale Road between Byhalia Road and Green T Road and widening it to five lanes. ==Exit list==
