I-90/WB E Sunset Way to E Fork Issaquah Crk - PCCP Replace & Deck Overlay

Project overview

On westbound I-90 just east of Issaquah, in late summer 2022 we added drainage and replaced about 1,550 feet of concrete panels with asphalt. Through summer 2023 we also will replace select concrete panels to smooth a 1-mile section of rough freeway about 1.5 miles west of SE High Point Way. In addition, repairs will take place at two bridges along the East Fork Issaquah Creek between Preston and Highlands Drive Northeast. This project is combined with another rehabilitation project on I-5 to reduce costs.

Summer 2022-fall 2023
Project status
$11.2 million

What to expect

People traveling on westbound I-90 between Preston and Issaquah between 7 p.m. and 6 a.m. weeknights should plan for overnight lane reductions. During these, our contractor crews will replace broken concrete panels. 

Four major weeklong lane reductions remain for westbound I-90 to rehabilitate concrete at two locations on westbound I-90 between Preston and Issaquah. This work will require:

  • Two weeks to replace concrete just before the I-90 bridge west of High Point Way.
  • Two weeks to repave the bridge about a mile east of the SE 82nd Street on-ramp near Preston.

In addition, crews will replace individual concrete panels during overnight lane reductions.

We will announce dates for this additional work when they are available.

We will replace or repair concrete on a mile-long section of westbound I-90 near Issaquah. We will also repair two bridges.
