Interstate 155 Missouri / Tennessee
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
The Carutherville Bridge across the Mississippi River opened to traffic in 1971.3 The section of Interstate 155 between Exit 4 (Simpson Road) and Exit 16 (U.S. 51 and SR 3) was completed in November 1979.4
MoDOT upgraded U.S. 412 to a four-lane expressway west from I-55/155 at Hayti to Kennett. A ribbon cutting ceremony for the final segment was held on June 29, 2007. The final phase cost $65 million and was completed in early July 2007.5
