Trip Plan
This 510.8-mile drive is best broken into two days, taking around 9h 41m total. Aim to leave early on your first day to maximize daylight and cover at least half the distance. With a fuel cost estimated at $116, plan your fuel stops accordingly, especially since the longest stretch on a single freeway is over 250 miles. You'll have two recommended stops, so use these to stretch your legs and refuel. Since most of the drive is on major freeways, you can maintain a good pace, but be aware of potential traffic, particularly in urban areas.
Morning Departure
Start early — leave by 6-7 AM to arrive at a reasonable hour.
Evening 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
9h 41m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.
