The Interstate 90 Floating Bridge will close several days this week when the Blue Angels return for Seafair. The Federal Aviation Administration requires the state Department of Transportation to close I-90 while the Navy aerial team performs for the safety of motorists and pilots.

No traffic, bicycles or pedestrians will be allowed on I-90 between Interstate 5 in Seattle and Island Crest Way on Mercer Island during aerial practices and performances, with traffic stopped up to 30 minutes before each flight. Also, the bridge will be closed to pedestrians and cyclists up to 30 minutes before posted closure times.

Exits from westbound I-90 to Island Crest Way and East Mercer Way will remain open, but expect heavy traffic at those exits during the bridge closures.

The I-90 express lanes will close at 9 a.m. on Thursday and at10:45 a.m. Friday, Saturday and Sunday.

Highway 520's Evergreen Point Floating Bridge remains open this week, but not to boat traffic. However, drivers using the Evergreen Point Bridge should expect heavy traffic and delays, and plan for extra time to cross Lake Washington.

•Friday (Aug. 3), 12:45 to 2:40 p.m.;
