Drivers who use State Route 520 to cross Lake Washington on Saturday morning should try to cross early or allow extra time.  The floating bridge drawspan will open at 11 a.m. to allow tugboat pushing a barge through to the other side.

Drivers will be alerted to the drawspan openings by electronic signs on highways leading to the bridge. Drivers should be prepared for a delay of at least 30 minutes or consider using Interstate 90 to cross Lake Washington.
