Key Considerations

• Elevation: I-80 crosses 7,000+ ft passes in WY (Evanston, Green River); winter chains may be required.
• Weather: WY/ID/OR mountain passes close in blizzards (Nov–Apr). Check 511 / state DOT sites.
• Fuel/food stops: Plan every 300–400 mi; services sparse in WY high desert.
• Time zones: Cross 3 zones (ET → CT → MT → PT). Gain 3 hours driving west.
• Alternate southern route (I-40/I-15): Longer (~2,550 mi) but lower elevation, less winter risk.

Tools

• Google Maps / Waze (real-time traffic).
• Furkot, Roadtrippers (multi-day planning).
