Multiple closures required for Seafair Air Show practice, shows

NEW — 6 a.m. July 30, 2015
As the U.S. Navy Blue Angels zoom above Lake Washington this week, drivers on Interstate 90 should prepare for traffic to slow to a crawl several times between Thursday and Sunday, and consider alternate routes.
The Washington State Department of Transportation is required by the Federal Aviation Administration 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.
The closures will extend from Interstate 5 in Seattle to Island Crest Way on Mercer Island. 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 Interstate 405, state Route 520 or state Route 522. Read more

One westbound lane will close for seven days
Drivers of westbound Interstate 90 should ready themselves for significant delays due to a $1.6 million construction project that begins July 18.
Westbound I-90 will be reduced to one lane near Bellevue Way for seven days as the Washington State Department of Transportation replaces the expansion joints on the East Channel bridge, which connects Mercer Island to Bellevue over a small channel of Lake Washington.

Prepare for traffic backups June 18-25 as workers repair two 92-foot-long expansion joints that are deteriorating on Interstate 90 near Mercer Island.
