Keep a close eye on your fuel gauge, as the $84 estimated cost can fluctuate based on local prices along these specific segments.

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
1 hour earlier
The destination clock does not match departure time, so double-check hotel check-in windows and late arrival plans.
Temperature spread
3 degrees cooler at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.

Salem, the capital of Oregon, is located in the Willamette Valley between Portland and Eugene. It is also the county seat of Marion County.
Salem was established in the early 1800s as a farming community. The town grew during the years of the California gold rush. Salem became the capital of Oregon in 1851 after it was moved from Oregon City. The capital was then briefly moved to Corvallis in 1855, but in that same year was permanently moved back to Salem. The first two Oregon State Capitol buildings tragically burned down. The third and current building was completed in 1938, complete with its distinctive gold-plated pioneer statue, the "Gold Man," perched atop.
Besides being the seat of state government, Salem is also a major agricultural center in one of the most fertile regions in the world.
