Seattle Celebrates Completion of Pier 58 and Announces Grand Opening Celebration for Waterfront Park.

Seattle's 20-acre Waterfront Park is complete with the opening of Pier 58. Mayor Bruce Harrell announced a grand opening celebration on September 6, 2025, featuring family-friendly activities and cultural programming. The park's transformation was a decades-long effort involving civic leaders, workers, and visionaries across the city. Pier 58 features a sea life-themed play area and expansive views of Elliott Bay. The completion of Waterfront Park is a once-in-a-generation civic achievement, similar to the Space Needle.
