Road Quality and Infrastructure Safety

Interstate 5 through the Cascade Siskiyou Pass between Redding and Ashland is well-maintained but can be congested during summer weekends. I-84 east of The Dalles features long straight stretches with occasional rough patches due to freeze-thaw cycles. I-15 south of Dillon is in excellent condition, though watch for wandering livestock near ranch exits. Winter driving is hazardous: snow and ice are common from November through March on the passes (Siskiyou Summit at 4,310 ft and Monida Pass at 6,870 ft). Summer brings afternoon thunderstorms with gusty winds across the high desert.

• Speed limits: 65–70 mph on interstates, lower in construction zones
• Emergency services: Cell coverage is spotty in rural stretches; carry a paper map
• Rest areas: Well-maintained state rest areas every 60–80 miles on interstates
