Seattle has limited toll infrastructure compared to other major cities. The main toll facility is the State Route 99 tunnel, which charges between $1.25 and $2.75 per trip depending on the time of day and traffic conditions. Peak hours typically cost more than off-peak travel.
Seattle Toll Costs
| Facility | Off-Peak | Peak | Usage |
|---|---|---|---|
| SR-99 Tunnel | $1.25 | $2.75 | Daily commute option |
Payment methods: The tunnel uses Good to Go!, Washington's statewide toll payment system. You can pay with a prepaid account, credit card at toll booths, or a Good to Go! pass.
Monthly Impact on Your Budget
Most Seattle commuters don't face regular tolls. If you use the SR-99 tunnel twice daily for 22 work days, you'd spend roughly $55 to $121 per month on tolls alone. That's minor compared to overall commute costs like fuel and vehicle maintenance, which typically run $150 to $300 monthly for average commuters.
Ways to Save on Commute Costs
Instead of focusing on tolls, consider these bigger cost-saving strategies:
- Carpool or vanpool: Split fuel and maintenance expenses with others
- Use public transit: King County Metro buses are often cheaper than driving
- Work from home part-time: Reduce commute days and vehicle wear
- Track all driving costs: Many commuters underestimate their true vehicle expenses by more than $4,500 annually when they don't account for fuel, insurance, depreciation, and repairs
