What's Happening Now?

We’re designing improvements to the bus stop on 3rd Ave S between S Washington St and S Main St to create a safer, more accessible, and more comfortable experience for people waiting for the bus. The project will help improve bus travel times and reliability by creating a better functioning bus stop and repairing and reconfiguring the street.

We expect to complete project design by late 2023 and begin construction in 2024. We'll have more information later this Spring about project design and opportunities for feedback. 

Project Overview

We’re designing and implementing this project in partnership with King County Metro. This project was first identified as part of the Third Avenue Transit Corridor Improvement Project, which began in 2015. The Third Avenue Transit Corridor stretches from Denny Way to S Jackson St, connecting Belltown, the Central Business District, and Pioneer Square. 

Each day the Third Avenue Transit Corridor is used by 65,000 people walking and rolling and provides transit connections for people riding the bus throughout the entire city and region. Prior to the pandemic, more than 2,500 buses used Third Avenue, moving more than 100,000 people each day. About 850 buses serving approximately 20 different bus routes use the bus stop at 3rd Ave S and S Main St each day. It is currently used by approximately 2,500 bus riders each weekday, making it King County Metro's 11th busiest stop.  

The existing bus stop at 3rd Ave S and S Main St currently lacks the accessibility and design features for such a busy bus stop. There are narrow sidewalks (9-11 feet) with no separation from the adjacent parking lot. There is only one bus shelter with limited lighting, no seating, and no electrical power. Improvements at the bus stop will include widening of sidewalks, repainting crosswalks, adding pedestrian lighting, planting new trees, and other bus stop amenities including: 

  • Bus shelters
  • Seating 
  • Real-time bus arrival information 
  • ORCA card reader

To help buses travel more smoothly, we’ll repair the road with new concrete paving and re-configure the street to be southbound only. The existing on-street parking on the east side of the street will remain but the direction will be reversed for the new southbound-only street design. 

Storm sewer improvements at 3rd Ave S and S Main St from Seattle Public Utilities Spot Sewer Repair Program are also being completed with this project.
