There is a lot to talk about when it comes to the 145th Street Corridor (SR 523), with significant information from the past, at present, and into the future.

PAST

Two studies have been completed:

145th Street Station Subarea Plan

In May 2013, Shoreline kicked off subarea planning for neighborhoods surrounding the future light rail station near 145th Street. Over the next few years, the City and community developed plans to address land use, transportation, park, and other needs to accommodate projected growth in these areas. The station vicinity area rezoning was adopted by Shoreline Council in the 145th Street Station Subarea Plan on September 26, 2016.

The 145th Street Multimodal Corridor Study

This study looked at the function of the entire 145th Street corridor from NW 3rd Avenue to Bothell/Lake City Way (SR 522). After a year-long process including public outreach, a preferred concept for the corridor was approved by Shoreline Council. Details of the study and the final report can be found under the 145th Street Multimodal Corridor Study.

PRESENT & FUTURE

Two Shoreline projects are currently under design as a result of the corridor study:

SR 523 (N/NE 145th Street) & I-5 Interchange Project

The Interchange Project which is currently under design will reconfigure the bridge deck to improve traffic flow, and will also build appropriate pedestrian and bicycle facilities with connection to the future light rail station. 

SR 523 (N/NE 145th Street), Aurora Avenue N to I-5

This part of the 145th Corridor is currently under design and will add safety and operational improvements including left turn lanes, street lighting, relocated utilities, a shared-use path in some sections and sidewalk improvements with off-corridor bicycle facilities in others. This area will be further segmented into separate projects for construction. The segment from I-5 to Corliss Avenue will be the first segment to be built.

Sound Transit Projects are also coming to the 145th Corridor:

Lynnwood Link Extension Light Rail

Light rail will be coming to Shoreline in 2024 with stations at 145th Street and 185th Street. The Sound Transit Lynnwood Link Extension will continue light rail from Northgate to Lynnwood City Center. Shoreline residents will be able to connect north to downtown Lynnwood (with an additional station in Mountlake Terrace) and south to the University of Washington, downtown Seattle, Sea-Tac airport, and more.

Bus Rapid Transit

(Visit the BRT webpage for upcoming Sound Transit open houses)
Bus Rapid Transit (BRT) east of I-5 on the 145th Corridor was voted for as part of the Sound Transit Plan 3 (ST3).  The route will service the Shoreline South/145th light rail station and run east along 145th Street, connecting to SR 522 (Bothell/Lake City Way) heading north/northeast through Lake Forest Park, Kenmore, Bothell, and Woodinville, providing more frequent and reliant bus service to this corridor.
