After a night working to address power issues, crews shut down the toll-collection system on the SR 520 Bridge about 6:30 a.m. today, Jan. 17.

Repair crews hope to get the system operating within a couple of hours.

Starting about 12:30 a.m., the toll system sent automated notifications about electrical issues to WSDOT’s vendor. Crews began to address and manage the problem, which continued periodically throughout the night until they shut down the system at around 6:30 a.m.

Drivers who crossed the bridge before 6:30 a.m. or so will be charged tolls. Drivers who crossed the bridge after crews shut down the system will not be charged. Drivers who have a Good To Go! account can check online to see if they were charged a toll. Please note that it sometimes takes a few hours for toll charges to appear in accounts.

Drivers who do not have an account will need to wait a week or two to see if the toll is included on their Pay By Mail bill.

Toll collections will resume on their regular schedule as soon as the system is repaired. Toll rates on the SR 520 Bridge are on a set schedule that varies by time of day.

The Washington State Department of Transportation said it is unknown how many transactions were lost during the outage. The agency will investigate the cause of the issue, as well as who might be responsible for lost toll revenue.
