3rd Ave Improvements

October 17, 2025

What's Happening Now?  

This weekend (Oct 17-20) we will continue installing the new, permanent water main on 3rd Ave between Virginia and Stewart. We do NOT expect to work while the No Kings March is happening, but will resume construction after the event concludes. See the schedule and map below:

Friday (Oct 17) 7pm to Saturday (Oct 18) 7am

We will close fully close 3rd Ave between Stewart St and Virginia St. (in the map above, this is the blue and orange hash-marked area)

Saturday (Oct 18) 7am-9am

We will close fully close the intersection at 3rd Ave & Virginia St for two hours. After 9am, we will reopen the road for full access. During those two hours, local access will be allowed from approaching streets (on the map, the orange diagonal grid box is the Virginia St intersection, and the streets leading to it are orange and blue hashmarks)

Saturday (Oct 18) 7pm to Sunday (Oct 19) 7pm

We will (again) close fully close the intersection at 3rd Ave & Virginia St for two hours. However, local access will be allowed from approaching streets 

Sunday (Oct 19) 7pm to Monday (Oct 20) 5am (if necessary)

We will reopen the intersection at 3rd Ave & Virginia St, but will keep 3rd Ave closed between Stewart and Virginia St. (i.e., the blue and orange hash-marked area)

Next Week (Oct 20 – 26) 

Once we complete our water main pipe replacement, we plan on cleaning and flushing out the newly installed pipe starting next week. We will also rebuild concrete vaults under the street surface and sawcut panels on the sidewalk limits. You can expect restricted nighttime access to the east side of 3rd Ave between Stewart and Virginia St from 7 PM until 7 AM. 

We will not host our weekly Q&A Session next Tuesday (October 21), but will resume our regularly scheduled meetings on October 28. See you there!

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.
