Starting this morning and through Sunday, motorists will likely encounter traffic delays associated with this weekend's big annual Seafair events - the Blue Angels air show and the hydroplane races on Lake Washington.
Drivers should note that extra travel time across Lake Washington may be needed as the Blue Angels' practice fly-overs require closures of the I-90/Lake Washington Floating Bridge for periods of time each day.
In addition, the fun-filled weekend will wrap up when 35,000 enthusiastic fans cheer on the Sounders against the Los Angeles Galaxy at 6 p.m. on Sunday evening.
The Seattle Department of Transportation (SDOT) urges drivers to help in the citywide effort to reduce pollution by leaving the car at home and trying one of the many alternate modes of transportation available - Metro Transit, the West Seattle Water Taxi, the Sounder commuter train, Link light rail, car pool, bicycle or walk, if feasible.
