Final paving of Zones A, B, and parts of C and D

Starting as early as September 13, crews will begin grinding the top several inches of asphalt along SW Avalon Way (Zones A, B, and parts of C and D). Crews plan to complete final paving on SW Avalon Way (Zones A, B, and parts of C and D) as early as September 18 and 19. Final paving is expected to be completed at night to minimize impacts for residents and commuters. As a reminder, road work is weather dependent and subject to change.

What to expect for grinding and paving:

  • Grinding to take about 1 day to complete and is expected to be completed during the workday, between 7 AM and 7 PM Friday, September 13
  • Grinding work is noisy and dusty. After grinding each side of the road, crews will use sweepers to clean up the work area.
  • Driveways will be temporarily closed as the grinding machine passes along the road
  • Access for emergency vehicles will be provided
  • Paving is anticipated to take place at night September 18 and 19 to minimize daytime traffic impacts
  • Driveways will be closed from 7 PM to 7 AM while we pave, asphalt is hot and stick and needs time to cure and cool
  • Fresh pavement is hot, oily, and extremely sticky. Please keep off new pavement if you are walking, especially with dogs, as the pavement can harm their feet and difficult to remove from fur.
  • We realize the inconvenience this work creates and appreciate your patience. Please contact the outreach team immediately if you have any accessibility needs or questions.

Zones C and D: Concrete work on SW Avalon Way just east and west of 35th Ave SW

Crews are beginning the concrete base paving work on SW Avalon Way. This concrete work will increase the lifetime of the road near the busy 35th Ave SW and SW Avalon Way intersection. Crews have begun on SW Avalon Way just east of the 35th Ave SW intersection. Crews must excavate the old pavement, form the new road base, pour concrete, then allow the concrete to cure for up to 3 days. Access to driveways will be closed while the concrete roadway is curing (outside of driveway) but newly poured driveways can anticipate a shorter cure time. As early as the week of September 16, there may be multiple 3-day closures of your driveways as crews form, pour and cure multiple lanes of Avalon Way. Work is weather dependent and subject to change.

Zone E: 35th Ave SW from SW Avalon Way to SW Alaska St

Base paving in Zone E has begun and will last for several months. Crews will continue to wrap up the east side of 35th Ave SW before switching to rebuilding the center lane and then west side of 35th Ave SW. Crews must form the new road base, pour concrete, then allow the concrete to cure for at least 3 days. Access to driveways will be closed while the concrete roadway is curing (outside of driveway) but newly poured driveways can anticipate a shorter cure time. Work is weather dependent and subject to change.

Upcoming Weekend Closures of 35th Ave SW and SW Avalon Way Intersection

We are phasing our work in up to 3 weekends to minimize night work noise for nearby neighbors and minimize our traffic impacts. This intersection must be rebuilt to extend the useful life of the road, make utility upgrades, and make transit improvement for people walking, biking, driving, and riding the bus. We have completed our first weekend closure and are beginning to plan our second. These closures will allow us to re-build the concrete roadway in the intersection. Crews need to close the intersection for the safety of people traveling and to allow for workers, large equipment, and trucks to maneuver throughout the work zone efficiently and safely.

Weekend closure #2: We have not confirmed a date for this next closure but will update this website once it is selected.

What to expect for all weekend closures:

• Closures to begin at 9 AM on Friday mornings.
• Closures to reopen by 6 AM on Monday mornings.
• Up to 2-3 weekend closures of 35th Ave SW and SW Avalon Way. Closures are not expected to be consecutive as this work is weather dependent and subject to change.
• Coordination with King County Metro on bus stops and routes.
• Detour routes and increased traffic on neighboring roads during closure times, please see our detour map.
• Breaking concrete and jackhammering causing noise, dust, and vibrations during daytime hours. However, some work may continue into the night to support opening the intersection Monday morning.

High Friction Surface Treatments: SW Genesee St between SW Avalon Way and 30th Ave SW and on SW Charlestown St between 46th Ave SW and 47th Ave SW

High Friction Surface Treatments (HFST) was completed on SW Charlestown St between 46th Ave SW and 47th Ave SW. However, there were issues with the equipment while crews worked on SW Genesee St.. We will reach out once we have a return date for the remaining work on the southern half of SW Genesee St between SW Avalon Way and 30th Ave SW. High Friction Surface Treatments are skid resistant layers laid down on areas where more traction is needed for the safety of people driving.

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.

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, the Seattle Department of Transportation (SDOT) 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 Plan, Pedestrian Master Plan, Transit Master Plan, and Freight Master Plan.
