Project Info

I-405 - NE 132nd St. Interchange Improvements

Project news

  • Preliminary engineering for this project began in July 2017.


WSDOT will construct a new half-diamond interchange to and from the north at NE 132nd Street in Kirkland. This project will improve access and reduce traffic congestion at this and other interchanges in the Kirkland area.

Why is WSDOT constructing this new interchange?
The I-405 interchanges at NE 124th and NE 160th streets in Kirkland are heavily congested.  Constructing the new interchange at NE 132nd Street will help ease bottlenecks at the NE 124th and NE 160th street interchanges.

The End Result
This new interchange will allow travelers to access I-405 to and from the north at NE 132nd Street rather than traveling only to the heavily congested NE 124th Street interchange.

Project Benefits

  • Safety. This project alleviates traffic congestion at the NE 124th Street interchange, reducing congestion-related collisions.
  • Congestion relief. Provides new access to I-405, allowing motorists to enter and exit the freeway in a less congested location.
  • Environment. WSDOT's I-405 Corridor Program team is designing the project to avoid and minimize impacts to the environment
