This journey takes approximately 8 hours and 4 minutes of pure driving time, making it a significant undertaking that is best split over 2 days. You should budget about $79 for fuel to complete the trip.

Trip Plan
To keep your 8-hour, 4-minute drive manageable, aim to depart early in the morning to beat local congestion. Since the route is split over 2 days, look for a midpoint accommodation that allows you to pace your 2 planned stops effectively. Keep an eye on your fuel gauge, as relying on local roads rather than interstates can sometimes make finding high-volume service stations less predictable; keep that $79 fuel budget handy for fill-ups. Given the reliance on secondary roads, allow for extra travel time beyond the estimated 8 hours to account for lower speed limits and potential local traffic. Prioritize steady pacing to ensure you arrive in New South Memphis refreshed rather than drained.

Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
For long drives, weather on day two can matter just as much as conditions at departure, so check the whole travel window rather than only the first day.
Time zone
1 hour earlier
The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.
