Interstate 69 (I-69) is a proposed US Interstate Highway that will pass through the western part of the US state of Tennessee, serving the cities of Union City, Dyersburg, and Memphis. State officials have considered building parts of I-69 as a toll road. Currently, a 21-mile (34 km) section of already-existing freeway in Memphis has been approved for the I-69 designation. A section near Union City is under construction.
