Atlanta to Marietta OH Road Trip Guide

The route from Atlanta, GA to Marietta, OH covers approximately 535 miles via I-75 North and I-77 North, typically taking 8 to 9 hours of driving time without stops. This corridor follows the path of the historic Dixie Highway through the Appalachian foothills, crossing the Tennessee River at Chattanooga and the Ohio River at Marietta.
