Closures of the I-90 floating bridge on Lake Washington will continue Friday and this weekend for the U.S Navy Blue Angels Seafair air shows over the lake.

The closures will affect all lanes of I-90 between I-5 and Island Crest Way on Mercer Island.

No stopping or parking is allowed on the floating bridge. By closing I-90, the Washington state Department of Transportation is complying with Federal Aviation Administration rules to create a safer environment for motorists and Blue Angels pilots by reducing distractions to both.

General closures

• Friday, July 31: Crews will close the bridge from 12:45 p.m. to 2:40 p.m. during the Blue Angels’ practice sessions. The center roadway will be closed from 10:45 a.m. to 3:30 p.m.

• Saturday, Aug. 1 and Sunday, Aug. 2: Crews will close the bridge from 12:45 p.m. to 2:40 p.m. for the full shows. The center roadway will be closed from 10:45 a.m. to 3:30 p.m.

The bridge will be closed to pedestrians and cyclists up to 30 minutes prior to posted closure times
