When I-90 Will Close For SeaFair Blue Angels Air Shows

Expect intermittent closures of I-90 over Lake Washington for SeaFair beginning Thursday.

MERCER ISLAND, WA - The skies above Lake Washington are rumbling with the sound of blasting F/A-18 Hornet engines, and that can only mean one thing: it's SeaFair time.
