Trip Plan
Given the local nature of these roads, try to avoid peak traffic hours to keep your 1 hour and 42-minute travel time consistent. Since you are sticking to surface streets, ensure your vehicle is fueled up before you leave, as the $12 estimated cost is based on standard consumption. With no planned stops, you have the flexibility to pull over whenever you need a break, but remember that navigating local intersections requires more mental energy than cruising on a highway. Keep a close eye on your navigation app, as the turn-heavy nature of the route means you will be making frequent adjustments to your path. Use this flexibility to your advantage by building in extra time for a casual rest whenever a convenient spot appears.

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
24 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
1h 53m on the road
