Trip Plan

Since the drive takes less than 3.5 hours, you can depart at your convenience without needing to worry about a rigid multi-day itinerary. Keep in mind that the majority of your time is spent on I-24, so try to time your departure to avoid peak traffic hours near major city centers.

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.
Time zone
1 hour earlier
The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.
Temperature spread
4 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
