What’s happening now?

Due to an anticipated very rainy weekend, we will not be closing the intersection of SW Alaska St and 35th Ave SW the weekend of December 27 - 30. Our next intersection closure is tentatively scheduled for Friday, January 3, starting at 9 AM. We will confirm this intersection closure date and future intersection closures through our email updates.

Construction information by zone

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.

Upcoming 35th Ave SW and SW Alaska St Weekend Intersection Closures:

To rebuild the concrete roadway, we will be closing the intersection of 35th Ave SW and SW Alaska St. We have completed the first of up to 3 intersection closures. We are doing work over the weekend to minimize noise and traffic impacts as much as possible. Work is weather dependent and subject to change.

As soon as Monday, December 30, we will begin excavation and concrete repaving on SW Alaska St. Please expect loud noise, dust, and vibrations while we complete this work. Driveways and alley access will be temporarily closed as we rebuild SW Alaska St. Advance notice will be provided to residents and business owners. 36th Ave SW will be open during the weekend closures of the intersection of 35th Ave SW and SW Alaska St.

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.
