SW Seattle Paving: 35th/Avalon Paving

Paving, protected bike lanes, transit lane, spot parking removal, center turn lane removal

People at a Rapid Ride bus stop

Updated: March 22, 2019

What’s happening now?

We are moving into the pre-construction phase of the project. Thank you to those that have attended any of our 4 open houses. Your feedback is valued, and it will be shared with the project team. Our most recent open house on March 14th had 47 attendees and we discussed topics of construction impacts, bus stop relocations, and project design clarification. 

Construction will begin as soon as mid-April and is slated to end in 2020. Our contractor has notified us that work will begin at 35th Ave SW Ave. We will share more information about our sequencing of work on SW Avalon Way and traffic configurations as we learn more from our contractor. 

You can learn more about the design elements and construction from our open house boards (board 1, board 2). 

During construction, please expect:

  • Construction to start as soon as mid-April and end mid-2020
  • Daytime, nighttime, and weekend work
  • Multiple closures of major intersections
  • Temporary bus reroutes and bus stop closures
  • Multiple, short-term driveway and sidewalk closures
  • Side street closures and temporary parking loss due to construction
  • Temporary water shut-offs

We encourage you to sign up for our email updates and start following SDOT on social media to stay up-to-date on construction activities. 

You can also learn more and see the changes in our plan sets below. 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).

Additional information about past decisions from the planning and design phases starting in 2017 in the project library at the bottom of the page.

Project Overview

Project map


Our plan is to pave 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.

Where we are in the process: Pre-construction process.

We have entered the pre-construction phase of the project. During this time our outreach team will continue to meet with local organizations and businesses about upcoming work. We will also flyer businesses and residences along the project corridor with more information on construction and sequencing of the project. Additionally, we will be sending listserv updates as construction approaches.

Final Design Update

January 2019

The planning and design phases for this project are now closed. We have our final design for these streets and the plan sets in place to pave and upgrade the infrastructure.

Since we last shared a design milestone update, we've made important design changes that will be included in the project we start building this year, including:

Closing 30th Ave SW at SW Avalon Way to people driving to reduce cut-through driving behavior

At our 60% design open house in August 2018, residents of 30th Ave SW told us about concerns with high-speed cut-through traffic. We will use plastic posts to close 30th Ave SW at SW Avalon Way to address these problems while still allowing emergency access and first responders to get to homes there quickly. In addition, we've done work for many years to make this complex intersection safer for people walking and biking. Removing one "leg" of this 5-way intersection will simplify it and make it easier and more predictable for everyone, especially people walking and biking along SW Avalon Way.

Adding new RapidRide transit island at SW Yancy St

The Seattle Bike Advisory Board requested full separation between people biking and transit instead of the proposed "mixing zone" on SW Avalon Way at SW Yancy St. Our final design includes a new transit island where people taking transit will board the bus on a concrete island extending from the sidewalk. People biking will ride in a separate bike lane behind the transit island. Learn about transit islands and see designs at this online resource. The transit island will feature such RapidRide amenities as a shelter, ORCA card reader, and real-time bus arrival information. Shifting northbound bus stop for routes 50, 55, and 21 at Luna Park

The northbound Metro bus stop at Luna Park by SW Charlestown St will be relocated about 150 feet north so it's opposite Luna Park Café at SW Orleans St. This will eliminate the bus-bike mixing zone proposed earlier in the design process, and add 2 new parking spaces, which were both things the community had requested. People biking northbound here will be routed onto the sidewalk, which will become a wider path, before the bus stop.

Reducing speed limits on SW Avalon Way and 35th Ave SW

Data shows that people driving on these busy streets are going faster than we want to see if we're going to meet our Vision Zero goals of no traffic fatalities or serious injuries by 2030. To make West Seattle streets safer for everyone, we ‘ll reduce the posted speed limit on SW Avalon Way from 30 MPH to 25 MPH, and on 35th Ave SW from 35 MPH to 30 MPH. The new speed limit will be in effect once new speed limit signs are installed. Experiences show that reducing speed limits by 5 MPH can lead to significant decrease in the percentage of people driving at higher speeds.

Installing skid-resistant surface treatment on SW Charlestown St and SW Genesee St

To address concerning crash patterns, we'll add a skid-resistant surface treatment to SW Charlestown St between 46th Ave SW and 47th Ave SW, and to SW Genesee St between SW Avalon Way and 26th Ave SW. Both streets are steep and people driving can lose control of their vehicles in cold or wet weather and when speeding.

Adjusting curb line and adding a new planting strip at 3246 SW Avalon Way

As part of the paving project, we'll move the curb line at 3246 SW Avalon Way south so it lines up with the curb lines of neighboring parcels. This means we can add new trees and a planting strip too.

Closing the slip lane from SW Avalon Way to Fauntleroy Way SW

To reduce crossing distances and institute a safety best practice, we'll close the "slip lane" at SW Avalon Way and Fauntleroy Way SW. 

Installing a new water main

As part of street reconstruction, a new water main will be installed near project area. This will require temporary water shutdowns for some customers. Seattle Public Utilities will work with property managers and businesses to determine the best times for shutdowns and provide advanced notice to impacted customers.

Construction preview

  • Expected to begin spring 2019
  • Expected to wrap up in 2020
  • Traffic control with lane closures and possible detours
  • Traffic congestion, longer travel times, and spillover traffic to adjacent streets
  • Sidewalk, bike lane, and side street closures with signed detours
  • 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 Plan, Pedestrian Master Plan, Transit Master Plan, and Freight Master Plan.
