It's beginning to look a lot like construction on I-405 in Totem Lake

By Victoria Miller

With the holiday season in full swing, it's possible that you are out on the roads doing some shopping for yourself or your loved ones. If you're traveling on Interstate 405 in Kirkland, you could be doing that shopping at the Village at Totem Lake. Do you ever wish there was another exit in that area? Well you're in luck because a new interchange is coming by way of the I-405/NE 132nd Street Interchange Project.

Why a new interchange?

We will construct a new on-ramp to northbound I-405 and a new off-ramp from southbound I-405 at Northeast 132nd Street, creating a half-diamond interchange that will complement the other half-diamond interchange at Northeast 116th Street farther south on I-405 in Kirkland. This new interchange will ease congestion on the local streets, improve non-motorized facilities, and provide an additional access point to and from I-405.

The project design also includes roundabouts at the future ramps, which will replace the traffic signals you see there today. We will create connections on Northeast 132nd Street to better manage traffic flow, and we will make sidewalk and bicycle lane improvements along both sides of Northeast 132nd Street and its connecting streets in the project area.

Once the project is complete, which is anticipated to be in 2024, travelers will have the option to access I-405 to and from the north at Northeast 132nd Street rather than traveling to the heavily congested Northeast 124th Street or Northeast 160th Street interchanges.

The I-405/Northeast 132nd Street Interchange Project is funded by the 2015 Connecting Washington funding package. The project is part of the I-405 Master Plan, which includes more than 150 projects designed to improve travel between Lynnwood and the Renton/Tukwila area.

What should I expect in the near term?

As of mid-November 2021, crews have begun pre-construction work including initial field investigations, surveying the work site, clearing brush, and conducting geotechnical borings. This work will continue in the first few months of 2022.

How can I find out more information?

Our team will be hosting its first quarterly public meeting at 12:30 p.m. on Wednesday, Dec. 15 via Zoom Webinar.
