Third Avenue Transit Corridor Improvements

October 1, 2015 \

Thanks to all who shared your thoughts — in person or via our online survey — on how best to improve Third Avenue for bus riders, pedestrians and visitors. We'll use the feedback we received to refine the project design and prioritize elements for the first phase of construction.

You can still learn about the design efforts underway on Third Avenue:

We'll continue to keep you informed and provide more opportunities to weigh in. Click here to sign up for email updates or to send us your feedback.

Third Avenue is downtown Seattle's most heavily used transit corridor. More than 2,500 buses travel the corridor every weekday and about 47,500 people board at bus stops on the corridor each day. Thousands of visitors, workers, shoppers and area residents also use Third Avenue daily.

To help create a positive and inviting environment for transit users and pedestrians, the Seattle Department of Transportation (SDOT) and King County Metro Transit are working together to make the corridor an inviting, accommodating, safe and attractive place where people want to be.

The Third Avenue Transit Corridor Improvements Project will complement and be coordinated with the many other improvement projects underway in the downtown area.

3rd Avenue Pike to Pine sidewalk & transit improvements nearing completion

Sidewalk and transit improvements begun in the spring along both sides of 3rd Avenue between Pike and Pine streets, as well as on Pine Street between 3rd and 4th avenues, are almost complete.

  • The temporary construction barriers on the sidewalk of the 1500 block of 3rd Ave (Pike-Pine) have been removed, restoring full access to the sidewalk.
  • The new "flexible loading zone" on the southbound (west) side of the street has been completed a week ahead of schedule and is in use.  The loading zone accommodates business deliveries and temporary parking during off-peak hours, while expanding bus transit load capacity during peak hours.
  • Pine Street between 3rd and 4th avenues has been restriped, creating 10 new back-in, on-street parking spaces, a commercial load zone, and 24-hour police parking.
  • During construction, the City also trimmed the street trees and improved the tree wells, upgraded the street lights with new LED lamps, and cleaned the pedestrian areas for a safer and more enjoyable pedestrian experience.

The project has been designed to improve the operational efficiency and commuter experience at these very heavily used bus stops, while improving also safety. 

This work was coordinated closely with the City's "9 ½ Block Strategy," a safety initiative which SDOT supported through modifications to the physical environment. 

SDOT and Metro are planning on keeping transit service at the temporary zones on Third between Pike and Union until the September service change on September 26th.

We Want to Hear from You!

SDOT and Metro want to know what you think will better connect and improve Third Avenue for transit users, pedestrians, business and visitors alike as we design future improvements along the corridor.

Project Background

The Third Avenue Transit Corridor Improvements Project is part of a larger plan to create a vibrant, safe and thriving Third Avenue. It will improve transit function and create a more welcoming urban environment along the corridor between Denny Way and Jackson Street.

This work is supported by federal and local funds and is jointly sponsored by the City of Seattle and King County.

Together, the Seattle Department of Transportation and King County Metro Transit are working to make the Third Avenue Corridor a more inviting, accommodating, and attractive place for transit users, pedestrians and visitors.

The project is moving towards 30% design in fall 2015. Based on initial feedback received last year, we have learned that the following elements are most important to people using the corridor:

  • Upgraded transit amenities
  • Improved lighting
  • Enhanced landscaping (more trees, planters)
  • Artistic elements such as murals and intersection features


The project has $8.1M to spend; including money for design and initial construction—which means everything cannot be built at once. To remedy this, the project is considering a phased approach to making improvements in the corridor.

Our funding comes with restrictions on how it can be used. About half of the project funds must be used on bus stop improvements and half on sidewalk and urban design treatments that support transit function.
