As of June 2020
Phase: Design 

The City is currently designing improvements for the 145th Street Corridor between Aurora Avenue N (including a transition to Linden Avenue/Interurban Trail) and I-5. The design will widen 145th Street to accommodate design elements that will improve traffic operations, safety and mobility throughout the corridor.

The project is planned for delivery in three phases:

  • Phase 1: I-5 to Corliss Avenue
  • Phase 2: Corliss Avenue to Wallingford Avenue
  • Phase 3: Wallingford Avenue to Linden Avenue

The first priority of the project is design, right-of-way acquisition and construction of Phase 1 by 2024. Phases 2 and 3 are funded for design, but will require additional funding for right-of-way acquisition and construction, and will proceed as funding becomes available.

Design Elements

The corridor will reflect the Preferred Design Concept approved by Shoreline Council on April 11, 2016. Design is focused on improving intersection safety and operations to reduce delays in traffic and create better access for pedestrians moving along the corridor and accessing the future light rail station at 145th Street and I-5. Design elements will include:

  • Improvements to signalized intersections, adding left turn lanes and adjusting signal timing.
  • A new signal at Ashworth Avenue.
  • Improved sidewalks and crosswalks, pedestrian countdown signals, and ADA accessible curb ramps.
  • A strengthened off-corridor bicycle network.

Project Funding

The design and environmental phase of the project is estimated to cost $5.560 million, and is primarily funded by federal and state grants. Overall costs to complete all three project phases from design through construction are currently estimated at $64.3 million.

Given the estimate for improvements and the competitive nature of grant funding, once design is completed for this section of the 145th Street corridor from Aurora Avenue N to I-5, the City will construct the improvements in three or more separate phases, similar to how the Aurora Corridor was implemented. Currently, the City has secured funding for a segment from I-5 to Corliss Avenue to be completed by 2024. The City will continue to seek funding for the construction of additional phases but expect this to be several years out.

Phases - 145th Corridor


The City of Shoreline conducted the 145th Street Multimodal Corridor Study in 2015-2016 to evaluate current conditions for all users of the corridor and consider transportation demands that will be the result of a future light rail station at approximately 145th Street and I-5. By working closely with the community and key stakeholders, the City tailored the improvements to maximize benefit while keeping community impacts to a minimum.

As a result of this study, Shoreline has received federal funding to complete design on two sections of the corridor: this project from Aurora Avenue (SR-99) to I-5 and the I-5 Interchange area. Both of these projects are now in the design phase. A third section of the corridor from I-5 east to Bothell/Lake City Way is a part of Sound Transit 3 that was approved in November 2016. Sound Transit will be addressing improvements on this eastern portion of 145th Street to incorporate Bus Rapid Transit (BRT) service, working with the City to engage the community and gather feedback from the public.
