Harbor Ave SW and SW Spokane St Intersection Improvements

Updated: May 23, 2019

A Note from the Outreach Team

Construction is complete and the protected bike signal has been activated at the intersection of SW Spokane St and Harbor Ave SW in West Seattle. These changes are intended to improve safety for people walking, biking, and driving at this intersection.

We'd like to thank residents, businesses, property owners, commuters, shoppers, and other community members for your patience and cooperation while we completed this Neighborhood Street Fund (NSF) project. The completion of the Harbor Ave SW and SW Spokane St Intersection Improvements Project would not have been possible without the community's support. 

Project Background

In 2016, the Harbor Ave SW and SW Spokane Street Intersection project was one of 12 selected by the Levy to Move Seattle Oversight Committee to be funded through the SDOT’s Neighborhood Street Fund (NSF) program. The NSF program funds projects requested by the community.

Final Design Concept

In early 2017, we presented an early design concept to the public through field visits, emails, and briefings with community groups. The feedback we received helped inform final design.

Project Funding

Funding comes from the 2015 voter-approved, nine-year Levy to Move Seattle, which will improve safety for all travelers, maintain streets and bridges, and invest in reliable, affordable travel options for a growing city. The levy includes $24 million to continue the Neighborhood Street Fund program over the nine years.
