Hyak/Stampede Pass

Crews will close the on- and off-ramps at the Stampede Pass interchange at exit 62 on Wednesday, Aug. 12 and Thursday, Aug. 13 as crews repair the ramps. To access Stampede Pass Road, drivers can travel east to exit 63, then turn around and travel west on I-90. The westbound ramps will not be affected. The detour for ramp access is approximately two miles round trip and there will be no delays for thru-drivers on the highway. During the week of Aug. 17, crews will remove and replace the concrete panels on I-90 directly under the Stampede Pass interchange. This section is very narrow and will require either a full or partial closure of this section of highway for the safety of our crews. Drivers are advised to follow message boards with reduced speeds of 25 mph and signs that will detour traffic using the on- and off-ramps at the Stampede Pass interchange. Crews will be working around the clock in order to complete this work. Drivers may experience backups up to five miles Monday, Aug. 17 through Thursday, Aug. 20. 

North Bend to Snoqualmie Summit / Westbound:

  • Single and double lane closures, nighttime only, Monday through Friday. 
  • Cyclists are being detoured to the John Wayne Pioneer Trail from the west summit, exit 52 to 468th Avenue, exit 32.
