Minimum Driving Distances on Washington state highways

• Distances are via the shortest, but not necessarily the fastest, route along state highways.
  
  
• Mileages that are bolded use ferry routes (zero miles) for minimum road mileage.
  
  
• Inter-mileages may be longer due to mountain pass closures (State Route 20 – Rainy/Washington Passes, and State Routes 410 and 123 – Chinook/Cayuse Passes).
