I-405/NE 132nd Street
Interchange Project

Online open house

The Washington State Department of Transportation is planning new connections to I-405 at NE 132nd Street in Kirkland.

Project 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 NE 132nd Street in Kirkland. This type of interchange is known as a half diamond. After this project is complete, travelers will have the option to access I-405 at NE 132nd Street, rather than traveling to the heavily congested NE 124th Street or NE 160th Street interchanges. Project development started in July 2017, and the improvements are expected to open to traffic in 2023.
