35th Ave SW and SW Avalon Way Intersection Update

Thank you for your patience during our intersection closure at 35th Ave SW Avalon Way! Work during the closure was successful and we were able to open the intersection early! At this time, we do not expect to have a third intersection closure and are working on remaining intersection work during typical hours.

We will update you on our final striping schedule once we have more information.

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

Crews have paved the south side of SW Avalon Way in part of Zone D (on SW Avalon Way, West of 35th Ave SW) and will continue work in Zones C and D. Please note:
  • Crews will continue pouring concrete on SW Avalon Way east of 35th Ave SW
  • 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

We are continuing work in Zone E and will continue for a couple more weeks. 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.

Stay informed

We will continue to share regular updates via email in addition to distributing flyers in advance of work near affected properties. Sign up to receive project emails using the form to the right or the bottom of this page.

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.
