What’s happening now?

West Seattle - thank you so much for your patience and understanding as we complete these necessary roadway improvements.

To follow the latest construction updates - sign up for our email updates or see our email archive for future intersection closure updates.

Construction Updated 

We are painting final stripes on 35th Ave SW and SW Avalon Way as soon as the week of April 6. We anticipate installing flex posts for the protected bike lanes at this time. You will see no parking signs go up on the road 3 days before work is planned to begin. This work will take 2 weeks to complete and is highly weather dependent.We will not be able to complete this work during wet weather.  

SW Snoqualmie St is now open. We anticipate completing grinding and final paving of SW Avalon Way between 35th Ave SW and Fauntleroy Way SW the week of April 6. When we grind and pave, SW Avalon Way from 35th Ave SW to Fauntleroy Way SW will be closed to traffic from 7 PM to 7 AM. Work is weather dependent and subject to change. Please see highlighted portions for updates on our paving schedule.

During nighttime grinding and paving the week of April 6, please expect:

  • Grinding on Monday night, April 6:
    • We will grind the road down to prepare the road for an overlay pave. This work will take place overnight, starting at 7 PM. Driveways will be temporarily impacted as equipment moves along the pavement
  • Paving on Wednesday, April 8 or Friday, April 10 at night:
    • Paving will take place after grinding and at night. This work is currently planned to at 7 PM, and is highly weather dependent. We will send updates to confirm when this work is taking place.
  • Nighttime work hours from 7 PM - 7 AM. Crews have a temporary noise variance to do night work.
  • Grinding and paving work will cause vibrations and the smell of tar.
  • Grinding and paving will take approximately one shift each to complete.
  • Anticipate driveway access on SW Avalon Way between 35th Ave SW and Fauntleroy Way SW to be impacted for a minimum of 2 night. We will let property owners know which night to expect this work, when confirmed, and emergency access will always be maintained.
  • Fresh pavement is hot, oily, and extremely sticky. Please keep off new pavement if you are walking, especially with dogs, as the oil and pavement can harm their feet and be difficult to remove from fur.
  • We will open driveways as they are safe for people walking and driving  

As a reminder, for the safety of our crews and your fellow residents, please follow posted detour routes and do not disturb traffic control. We anticipate laying down final striping in April, weather depending.

35th Ave SW and SW Alaska St: The week of April 6 we will be wrapping up work along sidewalk and will be working on ADA curb ramps at the east side of 35th Ave SW at SW Alaska St.

SW Avalon Way from 35th Ave SW to Fauntleroy Way SW: The week of April 6 we anticipate grinding and paving SW Avalon Way between 35th Ave SW and Fauntleroy Way SW. please see above for more information.

As we work on SW Alaska St, please follow King County Metro's Rider Alerts to stay up to date on bus stop changes.

Project Overview

Project map


Our plan is to rebuild the following streets starting spring 2019:

  • SW Avalon Way: SW Spokane St – Fauntleroy Way SW
  • 35th Ave SW: SW Avalon Way – SW Alaska St
  • SW Alaska St: 36th Ave SW – 35th Ave SW

Street redesign and rechannelization

We'll also redesign SW Avalon Way to add protected bike lanes and keep the inbound morning bus lane, and to remove some parking and the center turn lane.

Infrastructure upgrades

For all 3 paved streets, we’ll make pedestrian improvements and other infrastructure upgrades on all streets including accessible curb ramps and sidewalks, and upgraded street crossings.

In addition to repaving and rechannelizing roads, and improvements to curb ramps, sidewalks and street crossings, this project will include:

  • Closing 30th Ave SW at SW Avalon Way to people driving to reduce cut-through driving behavior
  • Adding new RapidRide transit island at SW Yancy St
  • Reducing speed limits on SW Avalon Way and 35th Ave SW
  • Installing skid-resistant surface treatment on SW Charlestown St and SW Genesee St
  • Adjusting curb line and adding a new planting strip at 3246 SW Avalon Way
  • Closing the slip lane from SW Avalon Way to Fauntleroy Way SW
  • Installing a new water main

Where we are in the process: Construction

We have entered the construction phase of the project. During this time our outreach team will continue to meet with local organizations and businesses about upcoming work and notify the community with email updates for what work to expect. We will also flyer businesses and residences along the project corridor with more information when needed as construction continues. During construction, please expect (En Español)

Curious how the project changed going into final design? We have detailed information about the new street design in a map, which includes parking removal and new lane layout, as well as a paving map, and text about what we're doing and how the decision was made (see Final Design Update below). 

Construction overview

  • Traffic control with lane closures and possible detours
  • Some night and weekend work to minimize traffic impacts
  • Traffic congestion, longer travel times, and spillover traffic to adjacent streets
  • Construction started April 15 and is anticipated to wrap up mid-2020
  • Multiple closures of major intersections
  • Temporary bus reroutes and bus stop closures
  • Multiple, short-term driveway, bike lane, and sidewalk closures
  • Temporary water shut-offs
  • Noise, dust, and vibrations
  • Large trucks, heavy machinery, and work crews

Program Description

Each year, we pave arterial streets in poor condition to make them safer, smoother, and to extend their useful life. Keeping our transportation system in a state of good repair helps lower the cost of future maintenance.

We prioritize paving based on pavement condition, traffic volume, geographic equity, cost, and opportunities for grants or coordination with other projects in the area. These are opportunities to redesign the streets for safety and build pieces of our citywide networks from the Bike Master PlanPedestrian Master PlanTransit Master Plan, and Freight Master Plan.
