Project overview
WSDOT and design-build contractor Graham Contracting, Ltd. 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. After this project is complete, travelers will have the option to access I-405 at Northeast 132nd Street, rather than traveling to the heavily congested Northeast 124th Street or Northeast 160th Street interchanges. The project design includes roundabouts at the intersections of the new ramps to better manage traffic flow. The design also includes sidewalk and bicycle lane enhancements along both sides of Northeast 132nd Street and along connecting streets in the project vicinity. The project also improves drainage, water quality and fish barrier correction to create over a half mile of new upstream fish habitat.
What to expect
Intermittent traffic delays at Northeast 132nd Street and 116th Way Northeast begin April 8
Crews on the I-405/Northeast 132nd Street Interchange Project have a busy month ahead of them as they continue making progress on various major project milestones.
See below for details about upcoming milestones crews are working diligently to complete.
Crews will install support structures near the intersection of Northeast 132nd Street and 116th Way Northeast from Monday, April 8 through Friday, April 19. To complete this work, crews will need to intermittently hold or stop vehicular and pedestrian traffic at the intersection to safely accommodate work activities.
Expect short periods of travel delays in the area, and plan ahead for occasional increased travel times. There will be flaggers onsite to assist with navigation as needed.
Northeast 132nd Street closed between 116th Way Northeast and Totem Lake Boulevard Northeast on April 12-15 and April 26-29
Crews will close Northeast 132nd Street between 116th Way Northeast and Totem Lake Boulevard Northeast on the weekends of April 12-15 and April 26-29 to complete paving and final striping work. A detour map for these closures can be found here.
Below is summary of traffic changes for drivers in the area:
- Northeast 132nd Street between 116th Way Northeast and Totem Lake Boulevard Northeast will be closed from:
- 8 p.m. Friday, April 12 through 5 a.m. Monday, April 15
- 8 p.m. Friday, April 26 through 5 a.m. Monday, April 29
- Travelers on eastbound Northeast 132nd Street use southbound 111th Avenue Northeast, eastbound Northeast 128th Street, and northbound Totem Lake Boulevard Northeast.
- Travelers on westbound Northeast 132nd Street use southbound Totem Lake Boulevard Northeast, westbound Northeast 128th Street, and northbound 111th Avenue Northeast.
- Local and business access will be maintained within the closure area with the assistance of flaggers.
- Pedestrian access will be maintained.
During the closures, expect travel delays and plan for increased travel times, especially during the most congested times of the day.
Paving work on local streets begins March 25
Crews will complete paving work throughout the project area from Monday, March 25, through Friday, March 29. Work areas include city roads throughout the project area and will vary as the work progresses. Below is a summary of what to expect:
- Monday, March 25, through Tuesday, March 26: Crews will complete daytime paving work on 116th Place Northeast and 116th Avenue Northeast.
- Wednesday, March 27, through Friday, March 29: Crews will complete nighttime paving work on additional city roads throughout the site. This work will take place at night to limit impacts to the traveling public and allow crews to safely complete paving operations outside of peak travel periods.
During all work activities, vehicular and pedestrian traffic will be maintained. Crews will use temporary single-lane closures with flaggers to allow traffic to travel safely in the area. Please plan ahead for increased travel times and expect periods of increased work noise. This work is weather-dependent and subject to change.
Completing the paving work is one of the final steps toward allowing crews to complete the I-405/Northeast 132nd Street Interchange Project by Spring 2024.
The project includes roundabouts at the intersections of the new ramps and Northeast 132nd Street.
