Washington State Department of Transportation bridge crews will open the drawspan of the State Route 520 Evergreen Point floating bridge to allow a tug boat to pass Saturday.

The bridge drawspan will open Saturday, Dec. 27 at noon. Drivers can expect up to a 30-minute delay to allow the vessel through.

Drivers will be alerted to the delay by electronic signs on highways that lead to the bridge. Drivers can take I-90 across Lake Washington to avoid delays.
