Trip Plan
To make the most of your 4-hour and 44-minute drive, try to depart early in the day to avoid potential congestion on local streets.

Keeping your $48 fuel budget in mind, be sure to fill up before hitting the more rural stretches where gas stations might be less frequent. Stay alert during the transition between town roads, as the frequent turns demand consistent attention throughout the entire trip.

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.
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
7 degrees warmer at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
