Kirkland closures
The I-405/Northeast 85th Street interchange in Kirkland will be closed from 11 p.m. Friday, May 8 to 4 a.m. Monday, May 11. Signed detours will be in place. Crews will shift traffic to a new roundabout on the freshly excavated Northeast 85th Street level.
The closure will include:

Northbound and southbound I-405 on-/off-ramps (Exit 18)
-
Both directions of Northeast 85th Street from 114th Avenue Northeast to 120th Avenue Northeast
Over the weekend, the 114th Avenue Northeast intersection will also be reconfigured into a roundabout using a temporary setup with signs and barrels. Construction of the 114th Avenue Northeast roundabout will continue over additional weekend closures this summer.
Beginning Monday morning, May 11, travelers will use two new roundabouts on Northeast 85th Street. Pedestrians will begin to use level two of the interchange, where Northeast 85th traffic was previously traveling while crews dug level one.
Travelers are also advised of additional closures on northbound SR 99 across the First Avenue Bridge, northbound I-5 across the Ship Canal Bridge and eastbound SR 520 in Seattle occurring at the same time.
“Know before you go," and plan for delays. Travelers are likely to encounter congestion in areas they typically do not associate with freeway construction, including local roads and parallel routes.
