We are collaborating with SPU to reconnect services at Stewart and remove temporary water main materials. You can expect restricted access on 3rd Ave between Virginia and Stewart St during nighttime hours, between 7 PM and 7 AM. This work will also involve water main shutoffs.  

We will also be reconnecting water services at Stewart St. To do this work, we will need to shut off water in the area (see the affected buildings in the map below) starting Wednesday, Nov 5, at 11 PM until Thursday, Nov 6, at 7 AM.

We will not work the weekend of November 8-9. Beginning Monday (Nov 10) we will:

  • Continue removing the temporary water main
  • Demolish concrete panels on the west side of 3rd Ave (the sidewalk and the curb) between Stewart and Virginia St
  • Repour concrete panels and add temporary striping for traffic

You can expect restricted access on 3rd Ave between Virginia and Stewart St from 9 AM on Friday (Nov 14) until 5 AM on Sunday (Nov 16). You can see the detour routes in the map below. This work is weather dependent, as the concrete needs time to dry.

For transit riders: 

  • King County Metro buses will divert off of 3rd at Lenora and Pike and head west and east to 2nd and 4th Ave, respectively. 

For Drivers: 

  • Drivers can continue on 3rd as well, but will need to divert onto Virginia or Stewart, before heading east to 4th Ave or west to 2nd Ave.

We will not host our usual weekly Q&A Session on November 11, as this is Veteran's Day, a City holiday.

Lastly, as part of the Holiday Construction Moratorium, we will pause our construction work from Thanksgiving (Nov 27) through January 1, 2026.

We thank you for your patience, and you can also contact our project outreach lead and subscribe to our email updates to learn more. 

Thank you for your ongoing patience as we work together to build a better 3rd Ave!

Overview

3rd Ave is Seattle’s busiest bus corridor and one of the busiest transit corridors in the state. Prior to the pandemic, it was traveled by more than 2,500 buses carrying 100,000 riders each day. This important bus corridor connects thousands of people walking, biking, and taking transit to jobs, housing, events, businesses and shopping centers, restaurants, cultural centers, service providers, and other transit connections to local and regional destinations. Over the next 2 years, we will be:

Building street, sidewalk, and bus stop upgrades in Pioneer Square

This includes upgrades to the southbound bus stop at 3rd Ave S and S Main St, and safety improvements for people walking, biking, and rolling at the intersection of 3rd Ave and Yesler Way. Click on the links to visit these project webpages to learn more.  

Paving 3rd Ave between Virginia St and Pine St, and between Yesler Way and S Main St.

Starting as soon as Summer 2025, we’ll begin repaving 3rd Ave between Virginia St and Pine St. While we rebuild the street, Seattle Public Utilities (SPU) will also replace an aging cast iron lead joint watermain between Virginia St and Pine St originally built in 1910.   

We began repaving 3rd Ave S between Yesler Way and S Main St in December 2024. Another crucial part of this work will involve SPU making repairs to their storm sewer system at the intersections of S Washington St and 3rd Ave S, and at S Main St and 2nd Ave Extension S.    

Repaving these sections of 3rd Ave will help buses travel more efficiently on smoother, stronger pavement. We are conducting ongoing outreach to impacted properties in advance of the paving and waterline work to help them prepare for construction.   

Working with King County Metro to upgrade real-time information kiosks at bus stops

Many of the existing real-time information kiosks don’t work anymore, and King County Metro will be replacing these kiosks. To get ready, SDOT will remove the existing kiosks and their foundations and build new foundations so Metro can install the new kiosks. The new kiosks will have real-time bus arrival information and ORCA cards readers to help people board the bus more quickly. King County Metro expects to start installing the new kiosks soon, and we will let the public know when once a timeframe is chosen.

These improvements are just one part of the City of Seattle’s bigger plan to make downtown safer, easier to get around, and more welcoming. Extending dedicated bus only hours on 3rd Ave also supports the Mayor's Executive Order on climate justice in transportation by investing in bus lanes. See our 3rd Ave Improvements factsheet for more information.

Funding

These 3rd Ave improvements are funded with various funding sources, including the voter-approved Move Seattle Levy and Seattle Transit Measure. Funding is also provided by Sound Transit grants, King County Metro grants, and the Landscape Conservation and Local Infrastructure Program.
