Reminder: Blue Angels I-90 & I-5 Closures

It’s SeaFair weekend, and that means that the Blue Angels are here!  Gotta love them…but, the traffic jams they cause can be pretty bad. Here’s some info to help you avoid the annual summer slow down.

I-90 will be closed to all vehicles, cyclists and pedestrians (both the mainlines and express lanes eastbound and westbound) between I-5 in Seattle to Island Crest Way on Mercer Island during the following times:

  • Saturday, August 1st:  11:50 AM – 2:40 PM
  • Sunday, August 2nd:  11:50 AM – 2:40 PM

* 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.

Several I-90 and I-5 ramps will close 30 minutes to one hour before Seafair Air Show times:

  • Northbound I-5 to eastbound I-90 (up to 30 minutes prior)
  • Southbound I-5 to eastbound I-90 (up to 30 minutes prior)
  • Northbound Rainier Avenue South to eastbound I-90 (up to 30 minutes prior)
  • Southbound Rainier Avenue South to eastbound I-90 (up to 30 minutes prior)
  • Eastbound I-90 to West Mercer Way (up to 30 minutes prior)
  • East Mercer Way to westbound I-90 (up one hour prior)
  • Island Crest Way to westbound I-90 (up to 30 minutes prior)
