Knoxville to Alton Road Trip: Hidden Gems and Guide

The roughly 520-mile drive from Knoxville, TN to Alton, IL traces the path of the Tennessee River's westward bend and the Mississippi River's meeting with the Missouri. This route, primarily along I-40 W, I-24 W, I-57 N, and I-55 N, crosses three states and spans about 8.5 hours of driving time. The section from Paducah to the Mississippi River delta was part of the historic Trail of Tears, a poignant layer of American history.
