3rd Ave Improvements
March 2024
What's Happening Now?
We’re getting ready to make changes to 3rd Ave in downtown and Pioneer Square to make buses more reliable and efficient, and streets safer and more comfortable for people walking, biking, and rolling. We’re currently designing many of these changes and expect to start implementing them in this year (2024). Now that we've reached 2024 and are poised to begin construction soon, we want to hear from you - please take our pre-construction survey. If you have questions about the project or would like a briefing, please contact the project outreach lead.
King County Metro bus drivers navigate 3rd Ave’s bus only lanes through downtown Seattle
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.
Expanding the 6 AM – 7 PM bus only restrictions on 3rd Ave three blocks north to Blanchard St.
In 2018, we began prioritizing buses on 3rd Ave by restricting the street to buses only from 6 AM – 7 PM each day between Yesler Way and Stewart St. We’re extending these bus only restrictions three blocks north from Stewart St to Blanchard St, which will complete our planned improvements to the 3rd Ave Transit Corridor. Extending the bus only restrictions to Blanchard St will help many high ridership buses with frequent service (such as RapidRide C, D, E, and Route 40) travel more efficiently and have reliable travel times.
The map below shows where we are extending the bus only restrictions, and the travel restrictions for all other vehicles when the bus only restrictions are in place. We plan to extend the bus only restrictions as soon as summer 2024.
- The 3rd Ave transit corridor is restricted to public transportation buses 7 days a week from 6 AM – 7 PM. This does not include school buses, work shuttles, or charter buses.
- Vehicles with commercial load zone permits can used designated loading zones on 3rd Ave from 9 AM – 3 PM.
- Vehicles other than public transportation buses can travel on 3rd Ave for up to one block to make deliveries and enter or exit driveways or garages. After traveling one block, vehicles must turn right off of 3rd Ave.
- Left turns are prohibited for all vehicles except buses.
- People biking can use 3rd Ave, although they are encouraged to use dedicated bike lanes on 2nd Ave and 4th Ave.
- Emergency vehicles are allowed to travel on 3rd Ave when responding to an incident.
Paving 3rd Ave between Virginia St and Pine St, and between Yesler Way and S Main St.
Starting as soon as summer 2024, 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 will also repave most of 3rd Ave S between Yesler Way and S Main St when we upgrade the bus stop at 3rd Ave S and S Main St starting in summer 2024. SPU will also make 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 will conduct additional 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 as soon as late 2024.

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.
