Lexington to Macon Road Trip: Ultimate Guide

Route 75 South from Lexington, Kentucky to Macon, Georgia covers roughly 470 miles and typically takes 7.5 hours of driving. This journey crosses the Tennessee border at mile marker 160 on I-75, where the Cumberland Plateau gives way to the rolling hills of the Tennessee Valley.
