Kentucky → Georgia · Interstate 65 / Interstate 64
Coming back from Louisville, Kentucky, to Atlanta, Georgia, the return leg also clocks roughly 609 km (378 miles) typically along Interstate 65 / Interstate 64, but the traffic picture shifts considerably compared with the outbound segment. Louisville, the largest city in Kentucky and home of the Kentucky Derby horse race, fades behind the wheel while the vehicle pushes back toward Atlanta, the capital of Georgia and largest economic and aviation hub in the Southeast, often after a full day of meetings, site visits, or prospecting calls. Plan 5h 48m plus a generous buffer against evening congestion, particularly on Fridays, holiday eves, or after major sporting events. Driver fatigue is the dominant concern returning home; mandatory rest breaks every two hours are non-negotiable. Fuel spend on the return stays near $50.97 for 55.4 liters (14.6 gallons). The corresponding reimbursement on the way back reaches $261.87 at $0.43/km. Combine both legs on a single Clara receipt to document the full round-trip cleanly, with separate timestamps for transparent audit defense.
