Harbor Ave SW and SW Spokane St Intersection Improvements

Updated: October 4, 2018

What’s happening now?

Thank you for your patience during our construction. We’re almost done, please hang in there.

We would’ve liked to be completed by now, but unforeseen events, such as the Local 302 strike and manufacturer’s delay, have pushed the construction schedule out. Now that the strike is over, our crews are doing what they can to finish construction as soon as possible.

In the coming weeks, crews will begin striping the intersection of Harbor Ave SW and SW Spokane St. Due to a manufacturing delay, crews are unable to activate the bike signal until October. Initially crews hoped to activate the signal and complete road striping at the same time. However, striping cannot be completed in the rainy months, so it may occur before the bike signal can be activated. In October, crews will also install fencing along the bike path and complete plantings in accordance with the City’s planting window.

Work completed to date

  • Paving and installation of new sidewalks and ramps
  • Replaced road panels
  • Cleared vegetation
  • Installed drainage pipes in the road
  • Installed electrical components for bike-only signal

What’s coming next

  • In September crews will stripe the road
  • In October, crews will activate the bike-only signal and reinstall fencing along the bike path
  • Replanting the site will begin as soon as October, per the City’s planting schedule

Traffic impacts

  • Westbound SW Spokane St will be occasionally reduced to one lane of traffic at Harbor Ave SW, except during peak hours (3 PM to 7 PM, Monday through Friday), when it will remain fully open
  • During work hours a uniformed police officer will direct right turns onto northbound Harbor Ave SW from SW Spokane St when lanes are reduced or closed
  • Sidewalks will be maintained for people walking and biking

What you need to know during construction

  • Typical construction hours are Monday-Friday, 7 AM-5 PM
  • Occasional night and weekend work
  • Temporary lane, crosswalk, and sidewalk closures
  • Detours for people walking and biking
  • A uniformed police officer will be on site whenever there is work underway at the intersection. A uniformed police officer or a flagger will aid people walking and biking whenever work within the trail alignment is underway or when other construction activities impact the pathway.
  • Possible parking and loading restrictions
  • Please expect typical construction impacts such as increased noise, dust, truck activity, and vibration
  • Impacts and schedule are subject to change

Again, thank you for your support as this project moves forward. We will post more details as soon as they are available. To receive information about the construction schedule and what to expect during construction, sign up for email updates.

Project Description

We will improve safety for people walking, biking and driving at the intersection of Harbor Ave SW and SW Spokane Street in West Seattle. 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.

Project Elements

  • Adding a curb bulb that increases standing space and visibility at the northeast corner of Harbor Ave SW and SW Spokane St intersection
  • Adding a bike-only signal at the northeast corner of Harbor Ave SW and SW Spokane St to give people biking protected crossing to the southwest corner of the intersection
  • Replacing existing segments of jersey barrier and vegetation along the Alki Trail approaching Harbor Ave SW
  • Restriping the crosswalk at the intersection
  • Adding a bike ramp on SW Avalon Way at SW Spokane St

Maintaining transit and freight access to Harbor Ave SW and Avalon Way SW is a key element of the project. Adding the protected bike signal phase will increase wait times at this intersection during some peak times of the day.

Project Benefits

  • Increase visibility of and safety for people walking and biking across Harbor Ave SW and SW Spokane St
  • Clarify a bike-only turning movement at SW Manning St and SW Avalon Way

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.

Public Outreach and Engagement

We are committed to keeping you informed throughout the life of the project. There will be several ways to engage with the project team through the design process this year. Sign up for email updates.
