Seattle's Waterfront Park opening celebration September 6, 2025 check out the Before and After photos

Seattle's new Waterfront Park will officially open on September 6, 2025, with a celebration organized by the City and Friends of Waterfront Park. This 20-acre park transforms the area from Pioneer Square to Belltown, replacing the former Alaskan Way Viaduct with green spaces, public amenities, and art installations. The project reflects over 15 years of community engagement, design, and construction, following the decision to build the SR-99 deep-bored tunnel. Managed as a public-private partnership, the park aims to enhance the urban landscape and foster community connections. A detailed schedule of events will be published in early August on the park's website.

City officials express excitement about the park's potential to serve as a gathering space for generations. The park's development represents a significant investment in Seattle's waterfront revitalization. This celebration marks a pivotal moment for the region, emphasizing collaboration and community spirit.
