Existing Conditions

The 100th Avenue NE corridor connects the north and south Juanita Business districts and leads to downtown Kirkland to the south, Bothell and SR 522 to the north and suffers from severe congestion and is deficient in sidewalk and bike facilities. The roadway transitions from a five-lane corridor with two lanes in each direction, sidewalks on both sides and a two-way left turn lane to a two lane roadway with no turn lane and no sidewalks on either side. The lack of a turn lane, a deficiency in the number of lanes, and deficient intersections at Simonds Road and NE 145th Street contribute to high congestion and an abnormally high incidence of accidents. The lack of non-motorized facilities contributes to dangerous situations for cyclists and pedestrians who choose to travel along the existing road shoulder. The existing roadway of 100th Avenue NE in the project area has short, discontinuous sidewalk and no bicycle facilities. Much of the corridor uses a striped shoulder for a pedestrian pathway, as a result, the corridor is unwelcoming to nonmotorized users. 100th Avenue NE also has significant congestion, which is anticipated to worsen over time, with anticipated intersection delays growing by an average of 72% by 2035.

Description of Improvements

The 100th Avenue NE Corridor Improvements Project will provide a solution to the need by establishing continuity with roadway improvements for the current 5-lane to 2-lane transition. The project will improve the existing roadway with a complete street design adding two additional travel lanes, a center left turn lane, continuous surface rehabilitation, wide sidewalks, a separated bicycle facility, and intersection improvements along 100th Avenue NE between NE 138th Place and NE 145th Street. Due to the overall project length, this project is broken into several sub-projects, with application's two roadway segments, two intersection improvements, and one culvert replacement being designed, bid and constructed concurrently. Future phases are planned south of these project limits to extend the upgraded sidewalk and bicycle facilities south to 100th Aveune NE and NE 132nd Street. The project elements included in this grant application will improve the existing roadway by widening the roadway from two to five lanes, installing new sidewalks, curb and gutter, bike lanes, illumination system, upgrading stormwater collection and treatment facilities, optimizing traffic signals and integrating with ITS, and providing urban design amenities. New or converted LED lighting is provided throughout. As a result, the project is intended to improve safety for all users for the corridor, reduce traffic congestion, and establish a community-supported identity for the corridor. Without the grant the City will build the culvert and intersection improvements to prepare for future road and nonmotorized improvements, but the significant discontinuity for nonmotorized users will persist and the queuing issues in the two lane section along with the related high rear-end accident rate will continue.
