SR 9/South Lake Stevens Road – Intersection Improvements

Project overview

Beginning in February 2022, Interwest Construction Inc., contractor crews working for WSDOT, will construct a roundabout at the intersection of SR 9 and South Lake Stevens Road to improve safety and mobility. Crews will also improve fish habitat by replacing the existing culvert under South Lake Stevens Road east of SR 9. There will be a creation of a new street, 24th Street Southeast, to be built by Costco. This new street will connect the remaining portion of South Lake Stevens Road to the west side of SR 9, via the new roundabout. The project is expected to be complete by fall.

The westside leg of South Lake Stevens Road, where it meets SR 9, remains closed for the duration of this project. The detour is 91st Avenue Southeast and 32nd Street Southeast.

In addition, the eastside leg of South Lake Stevens Road, where it meets SR 9, is now closed until September 2022.The detour for travelers on this side of the road is 99th Avenue Southeast/20th Street Southeast

Crews will also replace the existing culvert on the east side of SR 9. This part of the project will begin after July 5 due to the Washington State Department of Fish and Wildlife fish window for in-water construction.
