Trip Plan
For this 618-mile trip, splitting it into two days is the most sensible approach, aiming for an overnight stop around the halfway point. Leaving early in the morning on your first day will allow you to cover significant ground. The 10-hour, 59-minute estimated drive time suggests you'll need to manage your stops efficiently. Keep an eye on your fuel gauge, especially during the 212.4-mile stretch on I 45, as services can be spaced out.

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
5 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
10h 59m on the road
This is long enough that the arrival forecast matters almost as much as departure conditions. Recheck both ends before you roll.
