Costs of commuting over Snoqualmie Pass:

Keep in mind that RideshareOnline.com (outdated 2013 data) estimates commuting from the Cle Elum/Roslyn/Suncadia area to the Bellevue/Redmond/Seattle area can cost almost $15,000 per year and that doesn’t include vehicle repairs and vehicle failures such as flat tires, broken windshields, blown radiators, towing, rental car, time off work while waiting for vehicle repairs, spending nights in motels when Snoqualmie Pass closures due to avalanches, construction and/or accidents, etc.

AAA (outdated 2017 data) estimates the same Cle Elum/Roslyn area to the Bellevue/Redmond area round trip drive to cost closer to $24,000 per year!

AAA data from 2022 estimates the Seattle to Suncadia/Roslyn/Cle Elum round trip drive to cost upwards of $28,000 per year or about $2333 per month!

Here is another source to calculate the price of a mile/cost per mile to commute: https://www.commuterconnections.org/commute-cost-calculator/

Cost of “hours” or “the price of a mile” – estimated

  • Roslyn/Cle Elum to Bellevue/Redmond is roughly 80 miles one way depending on your exact start and stop location.
    • Add 10+/- miles for Seattle
    • Google maps tells you that Seattle to Suncadia commute is 80 miles but that is from exit to exit.
  • 80 miles twice a day = 160 miles
    • 160 miles 5 days a week = 800 miles per week
    • 800 miles per week X 50 weeks per year = 40,000 miles
  • To travel 80 miles at 70 miles per hour takes a little over 1 hour and 8 minutes.
    • No matter what route you take you will not average 70 miles per hour without breaking laws.
    • Round that 1:08 to 1:30 and it’s fair to say that it takes about 1.5 hours each way.
  • 1.5 hours each way is 3 hours per day and @ 5 days a week that equals 15 hours per week driving/commuting/sitting in your vehicle
  • Assuming 2 weeks a year for vacation you will roughly drive 50 weeks per year
  • 15 hours per week, times 50 weeks per year equals: 750 hours per year driving/commuting/sitting in your vehicle
  • Now take into consideration that those 750 hours of driving/commuting/sitting in your vehicle per year is if you are super lucky and don’t have any vehicle or traffic or weather or construction issues
