Interstate 155: Dyersburg, Tennessee to Hayti, Missouri

Take a drive through the Mississippi River Delta and into the Missouri Bootheel as we follow Interstate 155 from Dyersburg, Tennessee, to Hayti, Missouri. Though only 27 miles long, this short corridor carries an outsized importance, serving as the only interstate crossing of the Mississippi between Memphis and Cairo. The road links western Tennessee’s farmland to southeastern Missouri’s highways, creating a bridge—both literal and cultural—across the Mid-South.

Our journey begins in Dyersburg, where I-155 branches west from U.S. 51. Here, the setting is unmistakably small-city Tennessee, with retail corridors and local industry framing the interstate’s early miles. Quickly, however, the landscape opens into the flat expanse of the Mississippi Delta. Rows of cotton and soybeans stretch toward the horizon, punctuated by grain silos and the occasional tree line along drainage ditches. This fertile terrain has long defined life in Dyer County, and it forms the quiet prelude before we approach the river itself.

Leaving Dyersburg behind, the interstate passes the interchange with Tennessee State Route 181, a spur that connects travelers into the wetlands and wildlife areas along the Obion and Forked Deer Rivers. Here the highway begins to bend northwest, drawing us toward the water’s edge. Before long, the open fields give way to the levees and bottomlands that herald the great river crossing. Soon the steel outline of the Caruthersville Bridge rises ahead—a through-truss span completed in 1976. Crossing the Mississippi at this point is a reminder of both the engineering feats that made modern interstates possible and the river’s role as a barrier and gateway in equal measure.

As we roll across the bridge, the scenery is dominated by the broad sweep of the river itself. Barges may be spotted navigating the channel below, carrying grain, coal, or fuel along routes that mirror the highway’s purpose as a connector of commerce. On the far side, we enter Caruthersville, Missouri, a Bootheel town known for its riverfront and history as a Mississippi steamboat port. Interstate 155 immediately meets Missouri Route 84, giving quick access into town for those who wish to explore its historic downtown or the nearby casino and river park.

Continuing northwest, I-155 makes its final run through the Bootheel’s open farmland. The highway feels straight and unhurried, a reminder that this region is defined less by hills or curves and more by its boundless agricultural landscape. Farmhouses, irrigation rigs, and distant tree lines mark the roadside. Within minutes, we approach Hayti, where the interstate ends at a junction with I-55. From here, U.S. 412 continues west toward Kennett and beyond into northeast Arkansas, while I-55 offers swift connections north to St. Louis or south to Memphis.

Though brief, the drive along Interstate 155 offers a snapshot of the Mid-South’s geography and infrastructure. It ties together the fields of Tennessee, the waters of the Mississippi, and the farmland of Missouri—all within half an hour’s drive. More than just a connector, it stands as a reminder of the Mississippi’s enduring presence, and the role highways play in bridging not only rivers, but regions and communities.
