Project news

• Preliminary engineering for this project began in July 2017.
   

Overview
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.
