Bridge Deck Repairs Require Multi-Day Closures Starting in April on I-90 East of Issaquah

Round two of multi-day lane reductions on westbound Interstate 90 east of Issaquah starts Monday, April 10th, so the Washington State Department of Transportation (WSDOT) can repair several bridge decks between the Preston interchange at Southeast 82nd Street and Highlands Drive in Issaquah.

WSDOT currently has closures scheduled for four weeks this spring; four additional closures will be scheduled soon.

Four of these weeks continue the project WSDOT did on westbound I-90 late this past summer. In addition, later this spring, they’ll have two weeks with lane reductions on eastbound I-90 about a mile east of the Preston interchange to repair the bridge deck over the Raging River. WSDOT will also have two more weeks on westbound I-90.

When and where

WSDOT must reduce I-90 to a single lane for three to four days at each location. Each site will require two different lane reductions – one to do the left lanes, the other to do the right.

The first two-lane reductions are about 3½ miles west of the Preston interchange:

  • 10 a.m. Monday, April 10, to 6 p.m. Wednesday, April 12.
  • 10 a.m. Monday, April 17, to 6 p.m. Wednesday, April 19.

Another bridge will require two closures about a mile west of the Preston interchange:

  • 9 p.m. Sunday, May 14, to 4 a.m. Thursday, May 18.
  • 9 p.m. Sunday, May 21, to 4 a.m. Thursday, May 25.

These are 24/7 closures, not just overnight, so please take that into account as you travel.

Later, there will be two more westbound lane reductions about four miles west of Preston and two weeks with eastbound lane reductions at the Raging River.

Balancing necessary work and travel

This work will create challenges for people who use both directions of I-90 between Issaquah and Preston, but they need to do this work on the potholes not only on I-90 but around the region.

For this work, two of the bridges are part of a regionwide bridge deck preservation project. The other two are part of a project we started last year to replace damaged pavement on westbound I-90 and two bridges.

If you remember last year’s pavement repair work, there were significant backups to the Preston area and east, particularly during the morning commute. Not everyone has options, but if you do, consider the following:

  • Working at a remote location
  • Adjusting your travel schedule away from morning peak hours
  • Carpooling or using public transit
