Trip Plan
For this 651.9-mile drive, consider leaving early in the morning to maximize daylight hours, especially if you plan to complete it in one go. However, splitting the trip over two days is recommended to avoid excessive fatigue. Aim for around 6 hours of driving each day, which would put your overnight stop roughly halfway. Keep an eye on your fuel gauge, as the estimated cost is $102, and plan your refueling stops accordingly, especially during the longer stretches. The longest stretch without a significant change in road type is 99.2 miles on Central East Freeway.
Morning Departure
Start early — leave by 6-7 AM to arrive at a reasonable hour.
Evening Departure

Departure

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
11 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
12h 9m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.
