Leading east from SR 181 at Exit 2, Interstate 155 and U.S. 412 travel across the Obion River toward Lenox, Tennessee. 09/09/20
Interstate 155 is a rural freeway connecting I-155 and U.S. 412 at Hayti, Missouri with the Future I-69 corridor and U.S. 51 at Dyersburg, Tennessee. U.S. 412 overlays the entire route, which represents one of three Mississippi River crossings for the state of Tennessee.
The east end of I-155 provides a seamless connection with the U.S. 51 freeway leading northeast to Troy. U.S. 51 extends north from Troy to Union City as an at-grade four-lane highway. Construction on the 45-mile long section of future Interstate 69 from Dyersburg to the Kentucky state line got underway in the 1990s around Union City. However work was halted in 2012 due to a lack of federal funding. The state resumed work on the first of five segments in 2016. Costing $46.3 million, the 2.87 mile section will link SR 5 and U.S. 51 when it opens in October 2019.1
With passage of the Tennessee IMPROVE Act in 2017, work on the remainder of the $205.9 million Obion County sections north to Fulton, Kentucky and south to Troy advances. Completion of the new freeway is expected by 2020.1,2 I-69 will overlay the existing U.S. 51 freeway southwest from Troy to I-155 at Dyersburg. Minimal upgrades are needed to upgrade the route to Interstate standards.1
