The set of renderings above illustrates 100th Avenue Northeast's eventual lane-allocation with two vehicular lanes in each direction, a turn lane in the middle, sidewalk-level bicycle lanes and sidewalk along the edges.
Progress continues on an ambitious project that will transform the 100th Avenue Northeast corridor into a safer, more efficient street for all traveling modes, including walking, driving, riding transit and bicycles.
In this first phase, the City is building separated sidewalks and elevated bicycle lanes along both sides of the corridor, between Northeast 139th and 145th streets. The first phase will also improve traffic flow by creating two more vehicular lanes and optimizing 100th Avenue Northeast’s intersections with Northeast 139th, 145th streets and Simonds Road.
In 2020, the City of Kirkland completed one of the first phase's most ambitious tasks: installation of a new 10-foot-wide, eight-foot-tall culvert that will accommodate those extra two lanes of traffic and, at the same time, is providing access to a mile of upstream habitat for trout and salmon.
Many of the improvements derive from the 100th Avenue Northeast Study(PDF, 331KB) The City's Public Works staff hired the consulting firm of Concord Engineering to work with the community on 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.
