Fatigue management tips: stop every 2 hours, use rest areas, and switch drivers if possible. The Cascade Lakes Highway (OR-46) offers a scenic detour for Fresh Air.

I-5 is the primary artery, a well-maintained interstate with multiple lanes through urban areas. Expect toll-free travel except for optional express lanes in Portland (variable pricing). Gas stations cluster every 10–20 miles along I-5, with cheaper fuel in Oregon due to no self-serve (attendant required).

• Gas prices: WA averages $4.50/gal, OR $4.20/gal (2025 estimates)
• EV charging: Tesla Superchargers in Tacoma, Portland, Eugene, and Medford
• Rest stops: every 30–40 miles on I-5, including WA Welcome Center near Ridgefield

Portland's morning rush hour (7–9 AM) and evening (4–6 PM) can add 30 minutes. South of Eugene, I-5 narrows to two lanes each way through the Willamette Valley, with slower truck traffic on grades.

The drive begins in the Puget Sound lowlands, passing through dense evergreen forests near the Washington-Oregon border. The Columbia River Gorge, visible from I-5 crossing the Interstate Bridge, offers views of Beacon Rock—an 848-foot volcanic plug.

• Mount St. Helens: visible from I-5 on clear days; detour via WA-504 to Johnston Ridge Observatory
• Willamette Valley: rolling farmland, vineyards, and hazelnut orchards
• Rogue River-Siskiyou National Forest: old-growth douglas fir and serpentine soils

Local commerce thrives in small towns like Woodburn (outlet shopping) and Grants Pass (Rogue River jet boat tours). Jacksonville's historic Main Street features boutiques and the Britt Festival pavilion.
