    Step 1: Select a tolling scenario
    Scenario 1: Start tolling the new 520 bridge in 2016
    Scenario 2: Start tolling the 520 bridge in 2010
    Scenario 3: Start tolling the new 520 and
                                  90 bridge in 2016
    Scenario 4: Start tolling the 520 bridge in 2010,
                                  and 90 bridge in 2016

    Step 2: View details about this scenario
    • Only 520 is tolled
    • Tolling begins in 2016 when the 520 corridor is complete
    • Includes bridge and segment tolls (PDF)
    • Highest toll rate for comparison and analysis purposes ($0.90 - $3.80 each way)

    Time of day Toll you’d pay (each direction) 2007$*
    Morning (5–9 AM) $3.05
    Mid-day (9 AM–3 PM) $2.10
    Afternoon (3–7 PM) $3.80
    Evenings (7–10 PM) $1.95
    Nights (10 PM–5 AM) $0.90
    Weekends Varies from $0.75 to $1.50
    Segment Varies from $0.40 to $0.80
    Estimated funding ~$835 million

    Step 3: View results from this scenario
    • Estimated bridge funding ($835 million) does not meet legislative target of $1.5 – $2.0 billion
    • 2.7% of travelers choose HOV and transit
    • 1.1% of travelers choose a different time of day to travel
    • 5.8% of travelers choose a different route
    • 15.5% of travelers choose a different destination and do not cross Lake Washington

    Step 4: Let us know what you think

    Your opinion will help shape how tolling is implemented in the 520 corridor. Please send us your comments and share your ideas about questions such as:

    • What toll rate is reasonable to you?
    • How will your travel patterns change when 520 is tolled?
    • When should tolling begin on 520 – in 2010 or 2016?
    • Should I-90 also be tolled if it improves congestion in the entire cross-lake corridor?
    • What other tolling scenarios should be considered?
    • How will tolls affect low-income users?

Look at travel map for estimated travel speeds in the afternoon commute (3-7 PM)

The results above are initial results from travel and financial models, and are based on cash flow needed for the new 520 bridge, interest rates, and when tolling begins in each scenario. Toll rates and traffic information are useful for comparing the scenarios, not for precisely estimating traffic patterns or toll rates. You can print the scenarios for your reference. (PDF) For a more complete look at the scenarios and the results, see the committee's presentation (PDF) or a summary sheet (PDF) of initial results. You can also view additional maps to see how the scenarios affect estimated traffic volumes in 2010 (PDF) and 2016 (PDF).
