The big Seafair weekend is around the corner, and this year’s air show features the Patriots Jet Team flying over Lake Washington in a spectacular display of aeronautics.
The Federal Aviation Administration requires the Washington State Department of Transportation to close Interstate 90 while the Patriots Jet Team performs, for the safety of both drivers and pilots.
Which roads and ramps will be closed?
Interstate 90 will be closed to all vehicles, pedestrians and cyclists, eastbound and westbound, mainline and express lanes, between Interstate 5 in Seattle to Island Crest Way on Mercer Island on these dates:
- Friday, Aug. 2: 1:15 p.m. - 2:40 p.m., (Practice)
- Saturday, Aug. 3: 1:15 p.m. - 2:40 p.m., (Full show)
- Sunday, Aug. 4: 1:15 p.m. - 2:40 p.m., (Full show)
The bridge highrises will still be accessible to pedestrians and cyclists. However, no one on foot or bike can travel beyond the highrises up to 30 minutes prior to posted closure times.
I-90 east of Mercer Island will NOT be closed during the performance, although drivers should note that heavy congestion during these closures often restricts access to the exits.
The I-90 express lanes will close at 12:30 p.m. Friday, Saturday, and Sunday. The lanes will reopen to eastbound traffic by 3 p.m. each day.
