What’s happening now?

Work is happening in multiple zones on the corridor! Please see below for information about upcoming intersection closures, paving, and road demolition. Please sign up for our email updates to receive new information each week about where we are working and what to expect.

Second Closure of 35th Ave SW and SW Avalon Way Intersection

To continue rebuilding the concrete roadway, we will be closing the intersection of 35th Ave SW and SW Avalon Way for a second time. The 35th Ave SW and Avalon Way SW intersection must be rebuilt to extend the useful life of the road, make utility upgrades, and make improvements for people walking, bicycling, driving, and riding the bus. Closing the intersection will allow us to rebuild the concrete roadway as quickly and safely as possible. This intersection closure is weather dependent and subject to change.

The intersection will be closed as early as Friday, October 4 at 9 AM to Monday, October 7 at 6 AM, as long as weather allows. If there is rain in the forecast the weekend of October 4, we will postpone the intersection work to the following weekend, Friday, October 11 through Monday, October 14.

  • We will coordinate with King County Metro on bus stops and routes. Check Metro Rider Alerts for the most up-to-date information. 
  • No parking signs on 37th Ave SW and 38th Ave SW to accommodate metro buses and detour traffic.
  • Please follow posted detour routes

We are phasing intersection work in up to 3 weekends to minimize night work noise for nearby neighbors and minimize traffic impacts. Intersection 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.

Zones C and D: (SW Avalon Way from Fauntleroy Way SW to just east of 35th Ave SW)

As soon as the week of September 30 crews are preparing to pave the south side of SW Avalon Way in part of Zone D (on SW Avalon Way, West of 35th Ave SW). Please note:
  • Crews will continue pouring concrete on SW Avalon Way east of 35th Ave SW
  • Crews will begin breaking up the existing pavement west of 35th Ave SW as soon as Friday, September 27
  • There will be temporary, intermittent driveway impacts west of 35th Ave SW as crews complete this work. We will give you advanced notice as soon as we have solidified dates about when this work will happen

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 have completed the east side of 35th Ave SW and are now working in the center lane. Once work in the center lane is completed, crews will conduct base paving on the west side of 35th Ave SW. Crews will:

  • Form the new road base 
  • Pour new concrete 
  • Allow the concrete to dry 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.
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) were 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. Crews anticipate returning to complete the remaining work on the southern half of SW Genesee St between SW Avalon Way and 30th Ave SW as early as the week of September 30, weather depending. 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, 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.
