Reminder: I-90 Bridge Closures During Seafair Weekend, Aug. 2-4

The high-flying jets of Seafair will turn heads again this year, which means traffic on the Interstate 90 floating bridge will need to take alternate routes during FAA-required closures of the bridge.

The Washington State Department of Transportation (WSDOT) will close the I-90 bridge three times to drivers, walkers and cyclists this weekend while the Patriots Jet Team practices for and performs at the Seafair Airshow.

WSDOT will close I-90 from Interstate 5 in Seattle to Island Crest Way on Mercer Island during the Patriots’ practice flights and performances Friday, Aug. 2, through Sunday, Aug 4. Traffic will need to take alternate routes. Drivers should expect heavy traffic and delays in the greater Seattle and Bellevue areas.

Certain I-90 and I-5 ramps will also close 30 minutes to one hour before flight times. 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 I-405 or State Route 522.
