    Will the State Route 520 floating bridge be affected?

    The SR 520 floating bridge will remain open to traffic and tolls will be collected according to the rate schedule. Infrequent users of the SR 520 bridge may want to consider setting up a short-term Good To Go! account for Seafair weekend. Drivers crossing SR 520 should expect heavy traffic, significant delays and plan for additional time to cross the lake.
