I-405 - NE 132nd St. Interchange Improvements

Project news

  • Preliminary engineering for this project began in July 2017.

The Washington State Department of Transportation will construct a new on-ramp to northbound I-405 and a new off-ramp from southbound I-405 at Northeast 132nd Street in Kirkland. This type of interchange is known as a half-diamond.

Needs & benefits

Why is WSDOT constructing this new interchange?
Constructing the new interchange at Northeast 132nd Street will:

  • Improve access to the Totem Lake regional growth center and surrounding neighborhoods in Kirkland
  • Provide a new option to access I-405, creating an alternative to using local streets
  • Reduce pressure on heavily congested Northeast 124th Street and Northeast 160th Street interchanges
  • Build local street improvements, including two roundabouts at two intersections
  • Improve pedestrian and bicycle connections in the area
  • Make environmental enhancements, including fish passage and stormwater improvements

The End Result
This new interchange will allow travelers to access I-405 to and from the north at Northeast 132nd Street; provide local street improvements, including bicycle and pedestrian facilities; and install environmental enhancements, including stormwater improvements.
