Fuel and Route Economics

Fuel prices vary significantly along the route. Expect higher prices in remote areas of Oregon, especially in the Cascade Mountains. Plan to fill up in major towns like Redding, CA and Eugene, OR where prices are more competitive.

• Average gas price per gallon: CA $4.50, OR $4.00 (as of 2025)
• Total fuel cost estimate: $100-$130 for a mid-size sedan
• Recommended gas stations: Shell, Chevron, and regional brands

Road Conditions and Quality

Interstate 5 is well-maintained with regular rest areas. However, OR-126 and US-20 are two-lane highways with occasional rough patches, especially after winter. Check ODOT road reports for construction delays.

• I-5: Smooth, heavy truck traffic
• OR-126: Curvy, scenic, watch for logging trucks
• US-20: Mountain passes, ice possible Nov-Apr

Rest Zones and Fatigue Management

Oregon requires drivers to stop every 2 hours. Plan rest stops at the many rest areas along I-5: near Yreka, Weed, and Canyonville. Further east, rest stops are scarce; use the McKenzie River area for a break.

1. Rest Area 1: Weed, CA (Mile 745 I-5) - picnic tables, restrooms
2. Rest Area 2: Canyonville, OR (Mile 98 I-5) - vending machines
3. Rest Stop 3: McKenzie Bridge, OR (OR-126) - no services, scenic river
