Trip Plan
For this 665.9-mile route, splitting the drive over two days is highly recommended. Departing early on your first day will allow you to cover a substantial distance and reach a midway point comfortably. With an estimated 11h 50m of driving, aim for around 5-6 hours of travel each day. Keep an eye on fuel stops, especially during the longest stretches, and utilize the 3 planned stops to stretch your legs and refuel.

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
4 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
Road read
11h 50m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.

It helps. This route has a higher-than-average number of complex decision points, which get harder in the dark. If the last hour of the trip is on surface roads or mountain grades, aim to arrive at Amarillo, TX before sunset when you can. Check the Trip Plan for departure windows that land you in daylight.
Only with planning. This is a long drive for kids — consider splitting it into two days rather than pushing through. Plan at least 3 meaningful breaks. Dedicated rest areas are limited, so plan gas or food stops as your bathroom breaks.
