- Construction is complete for the I-405 Kirkland Nickel Stage 1 Project
Why is WSDOT
Improving I-405 in Kirkland?
The Kirkland Nickel Stage 1 Project is WSDOT's first step toward completing the comprehensive plan to decrease I-405 congestion and improve commutes through the corridor.
The End Result
WSDOT and its design-build contractor, Kiewit Construction, recently completed:
- One new lane in each direction of I-405 between NE 85th and NE 124 Streets;
- Three wetland mitigation sites;
- A wider I-405 bridge over NE 116th Street;
- Improvements to the I-405/NE 116th Street Interchange (pdf 314 kb);
- An improved, fish-passable culvert under I-405 at Forbes Creek; and
- Three new noise walls.
WSDOT will begin constructing the Kirkland Nickel Stage 2 project in 2009 as an element of the larger SR 520 to I-5 Widening Project. Stage 2 will address an additional lane northbound from 70th to 85th and southbound from SR522 to NE 124th and NE85th to SR520.
Congestion relief. Improves traffic flow in the area known as the "Kirkland Crawl" and improves merging from NE 85th Street to northbound I-405 and from NE 116th Street to southbound I-405.
Safety. Traffic flow improvements help reduce congestion-related collisions such as rear-ends and side-swipes.
Environment. Improves fish passage under I-405 at Forbes Creek, improves wetlands near I-405 at Forbes Lake, and constructs three new noise walls.
