Trip Plan
For this 561.4-mile drive, it's wise to get an early start to maximize daylight and distribute the driving over two days. With an estimated 8-hour and 22-minute duration, planning for one overnight stop will make the trip more enjoyable. Factor in the $86 fuel cost and locate gas stations strategically, especially since there are two planned stops. Consider starting your journey on a weekday to potentially encounter less traffic on the main roads. Taking advantage of the two recommended stops will help you manage fatigue on this long stretch across Texas.

Start early — leave by 6-7 AM to arrive at a reasonable hour.

Departure
Before you leave

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
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
10 degrees warmer at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
Road read
9h 58m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.
