Why Kirkland wants to redesign and rebuild 100th Avenue Northeast
(Sept. 17, 2015 PDF 650 KB)
Construction begins summer 2020 on one of the 100th Avenue Northeast Improvements project’s most ambitious tasks: reconstruction of the Cedar Creek culvert.
The existing three-decade-old box culvert blocks salmon and trout from swimming upstream and limits the roadway’s width to three lanes. The new 10-foot-wide, eight-foot-tall culvert will accommodate an extra two lanes of traffic and, at the same time, provide access to a mile of upstream habitat for trout and salmon. Reconstruction of the Cedar Creek culvert is the first in a series of Phase I improvements the City will be implementing along the corridor’s northern half-mile, between Northeast 139th and 145th streets.
Other Phase I improvements include separated sidewalks and elevated bike lanes along both sides of the corridor. The first phase will also optimize traffic flow and safety at 100th Avenue Northeast’s intersections with Northeast 139th, 145th streets and Simonds Road.
The 100th Avenue Northeast Study is available to review under important information on the sidebar of this webpage. The City's Public Works staff hired the consulting firm of Concord Engineering to perform a study of the 100th Avenue Northeast Corridor. The Study analyzed safety improvements for pedestrians, general travel lane configurations, and associated environmental issues between Northeast 132nd and Northeast 145th Streets. Other considerations will include traffic flow, and future anticipated growth. The final product from the Study will be used as the basis for future grant funding opportunities.
