Trip Plan

If you find yourself tiring, use your single stop as an opportunity to stretch and reset before tackling the final transition onto US-50. Planning your fuel stop strategically will help you keep your costs close to the $43 estimate.

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

32 degrees warmer at arrival

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