The $10 in free SR 520 tolls was a limited time offer that is no longer available.

Customers who purchased and activated a Good To Go! Pass by April 2011 will see up to $10 in free tolls for the SR 520 Bridge credited on their monthly statement. This credit will be applied after they have accumulated SR 520 tolls on their account.

More on how the $10 is added to your account:

Your account will be credited back for all SR 520 Bridge toll transactions until the $10 credit has been used, or until the promotional period ends - March 31, 2012. This is similar to a refund rather than a deposit of $10 to your account.

Details:

• Passes must have been activated by April 15, 2011 to receive the offer.
• Toll credits are only valid for the SR 520 Bridge tolls and must be used by the end of the promotional period - March 31, 2012.
• The credit will post to your account at the end of each month for SR 520 tolls (after tolls have been accumulated) until the entire credit amount has been used. The credit will be shown on your monthly account statement.
• You can receive $10 in free tolls per Pass, up to six Passes, applied toward one account.
• Promotion applies only to new Good To Go! accounts.
• Offer is valid on registered Good To Go! Pass accounts only (commercial accounts, Pay By Plate and unregistered accounts are ineligible).
• You must have registered your Pass(es) and activated your account with the minimum $30 opening balance in order to receive the $10 toll credit.
• Toll credit has no cash value and cannot be refunded.
