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
2 hours later
The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.
Temperature spread
32 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
30h 17m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.
