ABOUT THE PROJECT

Pioneer Square East West Pedestrian Improvements

Working with community partner Alliance for Pioneer Square, we have designed and will construct improvements on portions of King, Main and Washington Streets, Yesler Way and 2nd Avenue S to prioritize pedestrians, improve sidewalks and increase greenery. The project will also reduce the number of vehicle travel lanes and limit traffic flow directions on portions of these streets in order to move vehicles away from structurally vulnerable areaways and optimize traffic operations and circulation in the Pioneer Square area. This project aims to improve accessibility for people of all ages and abilities and provide safe, convenient and graceful pedestrian connections.  We anticipate that construction of this project will begin in early 2024 and continue for approximately a year. Construction will begin on S Washington Street and S Main Street, between 1st Ave S and Alaskan Way S. 

On September 17, 2020, we issued a Determination of Nonsignificance (DNS) for these improvements, supported by an Environmental Checklist, in accordance with the State Environmental Policy Act (SEPA).

Washington Street Boat Landing Pergola

The Washington Street Boat Landing and Beach will restore access to the waterfront for Pioneer Square and the South Downtown community. The landmark pergola structure has been a piece of Seattle's waterfront since the early 20th century, and with its recent restoration, it once again serves as a symbolic gateway to the city from the Puget Sound. The pergola has been fully restored, but it will remain closed to the public until the park promenade has been constructed.

Pioneer Square Habitat Beach

Between Colman Dock and Pier 48, a new habitat beach supports the waterfront ecosystem, including enhancing the salmon corridor by adding rocks and nearshore vegetation. Improvements to the marine habitat began in October 2018 thanks to an agreement between Washington State Ferries and the City of Seattle to make these improvements on State-owned property. The plantings on the shoreline restore the function of a natural shoreline and improve ecosystem productivity. Check out this coloring page that explains the different layers that make up the beach.  

The Pioneer Square Habitat Beach opened to the public on July 1, 2023. The beach is open every day from 7AM to 10 PM. Because the beach is a key component to Seattle’s nearshore marine habitat, some rules to keep in mind before heading down include no swimming or entering and exiting the water by personal watercraft, and packing out what you pack in. Additional rules and regulations can be found on the Friends of Waterfront Seattle website and are posted on-site.
