Online open house starts May 16 for project to improve fish passages under I-90 in Bellevue

Learn more about $109.5 million project and how it will affect traffic

BELLEVUE – Construction begins this spring on a $109.5 million project to improve fish migration and restore natural stream conditions for Sunset Creek under Interstate 90 in Bellevue and people can learn more about the project in an online open house.

The Washington State Department of Transportation is hosting the online open house starting Tuesday, May 16, to provide more information about this critical fish habitat restoration project and what travelers can expect during construction.

Atkinson Construction, working for WSDOT, will build four new bridges under I-90, Southeast Eastgate Way and Southeast 36th Street in Bellevue. The work is scheduled to finish in fall 2026.

This work is necessary because the existing culverts under I-90 are too high above Sunset Creek for fish to pass through them. Once complete, this project will remove barriers to almost two miles of habitat for salmon, steelhead and other species.

WSDOT has concentrated its work to improve fish migration throughout western Washington following a 2013 federal court injunction. The I-90 Sunset Creek project is part of the 2030 Fish Passage Delivery Plan to open 90 percent of habitat blocked by state culverts.

Slow down – lives are on the line. 

In 2023, speeding continued to be a top reason for work zone crashes.

Even one life lost is too many.

Fatal work zone crashes doubled in 2023 - Washington had 10 fatal work zone crashes on state roads.

It's in EVERYONE’S best interest.

95% of people hurt in work zones are drivers, their passengers or passing pedestrians, not just our road crews.
