I-405/Northeast 132nd Street Interchange Project

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

Upcoming traffic shifts and road closures

Traffic lane reduction on Totem Lake Boulevard Northeast in early July

For approximately one week in early July, Totem Lake Boulevard Northeast will be reduced to one travel lane during the daytime for sanitary sewer installation work. We will share specific dates and times once plans have been finalized.

• Northbound and southbound traffic will alternate.
• Access to properties on the east side of Totem Lake Boulevard Northeast will be maintained.
• Flaggers will be posted at both ends of the lane reduction area to facilitate traffic flow.
• A uniformed traffic control officer will be present to facilitate traffic flow.

 

Traffic and pedestrian route shifts for a new construction phase starting this summer

As part of ongoing construction activities, crews will put a new roadway alignment in place along Northeast 132nd Street, 116th Avenue Northeast, and Totem Lake Boulevard Northeast. This shift will take place later this summer and will allow crews to establish new work zones and move into the next phase of construction.

Traffic lanes along Northeast 132nd Street will shift north within the project area, and the left turn restrictions from westbound Northeast 132nd Street onto southbound 116th Way Northeast will remain in place. Similarly, pedestrian routes will shift to the north side of Northeast 132nd Street.
 

Full closure of intersection at Northeast 132nd Street and Totem Lake Boulevard Northeast July 7-10

Northeast 132nd Street will be closed between 118th Avenue Northeast and 116th Way Northeast. Totem Lake Boulevard Northeast will be closed at Northeast 132nd Street. This closure will last from the evening of Friday, July 7 through the morning of Monday, July 10 and will allow crews to complete fish culvert installation work in the area.

• Westbound travelers on Northeast 132nd Street can use Northeast 128th Street via 120th Avenue Northeast.
• Eastbound travelers on Northeast 132nd Street can use Northeast 128th Street via 116th Way Northeast.
• Local access on Totem Lake Boulevard Northeast will be maintained.
• Access to the Kingsgate Park and Ride will be maintained.
• A signed detour will be in place during this temporary intersection closure.

 

Closure of Totem Lake Boulevard Northeast at Northeast 132nd Street in late July

Access to and from Totem Lake Boulevard Northeast at Northeast 132nd Street will be restricted from a Friday evening through the following Monday morning in July. This closure will allow crews to complete fish passage installation work in the area. We will share specific dates and times once plans have been finalized.

• Northbound travelers on Totem Lake Boulevard Northeast can use 116th Way Northeast or 120th Avenue Northeast via Northeast 128th Street.
• Southbound travelers on 116th Avenue Northeast can use 120th Avenue Northeast or 116th Way Northeast via Northeast 132nd Street.
• Local access on Totem Lake Boulevard Northeast will be maintained.
• Access to the Kingsgate Park and Ride will be maintained.
• A signed detour will be in place during this temporary roadway closure.

 
Travelers should expect to see traffic signage, orange traffic barrels, and construction crews and equipment in the area of I-405 and Northeast 132nd Street.

Construction activities will generally include installing signage, placement of erosion control (orange fencing, straw), temporary striping/lane shifts, signal adjustments, third-party utility relocation (Ziply Telecom), sidewalk and roadway demolition, retaining wall construction, and new sidewalk construction.

Construction will occur primarily on weekdays during daytime hours but may include nighttime and weekend work when necessary. Nighttime and weekend full closures could occur during construction with detours and potential delays.

During construction, traffic conditions are expected to remain similar to existing conditions during the most congested times of the day, although some short-term delays may occur. Residents and commuters may experience noise, vibration, dust, debris, crosswalk and sidewalk closures, lane and shoulder closures, restricted turn movements, and detours for pedestrians and bicyclists. Nearby driveways and other access points to neighborhoods and businesses will remain open throughout construction.

We will work to minimize the effects of construction for nearby neighbors and travelers and reduce inconveniences to motorists with up-to-date information about traffic and travel options.
