Gatlinburg to Memphis Road Trip: A Complete Guide

The drive from Gatlinburg, TN to Memphis, TN spans roughly 400 miles along Interstate 40, threading through the Great Smoky Mountains, the rolling hills of Middle Tennessee, and the flatlands of the Mississippi Delta. This route, completed in 1969, was the first interstate to connect the Atlantic to the Pacific. It's worth driving because it offers a condensed cross-section of American culture, from Appalachian craft to blues music.
