Multiple ramp closures also required for Seafair Air Show practices, shows

SEATTLE – The U.S. Navy Blue Angels will be one of the few things traveling fast across Lake Washington when they take to the sky Thursday, Aug. 3, through Sunday, Aug. 6.

The Federal Aviation Administration requires the Washington State Department of Transportation to close the Interstate 90 floating bridge five times to drivers, cyclists and pedestrians while the Blue Angels practice for and perform at the Seafair Air Show. The closures are to keep the public and pilots safe and to minimize distractions.

Westbound I-90 will close at Island Crest Way on Mercer Island. Access to eastbound I-90 will close at I-5 in Seattle. In addition, several I-90 and I-5 ramps will also close between 30 minutes to an hour before each practice and show time. Drivers who need to cross Lake Washington should plan to do so at least one hour before the closures or use an alternate route, such as Interstate 405, State Route 520 or SR 522.

Pedestrian access to I-90

SR 520 open during I-90 closures
During the I-90 closures, 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.
