With a highway share of 0%, you should prepare for a more involved, hands-on journey that requires your full attention on the road.

Expect a mix of faster highway mileage and slower local approaches near the beginning or end.
There are about 24 navigation steps in the underlying route data, so the final approach matters more than the middle miles.

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
20 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
