Seattle pulled it off. After years of construction, detours, and debate, the city is getting another major piece of its waterfront back.

Pier 58 officially reopens Friday, July 25, as part of the 20-acre Waterfront Park transformation. What was once a crumbling concrete deck is now a bright, marine-themed play zone with a 25-foot jellyfish-inspired climbing tower, an 18-foot slide, a tree grove, and an elevated lawn with views of Elliott Bay.

The playground was shaped by community input, including ideas from Seattle’s youth. It adds nearly 50,000 square feet of public space to the downtown waterfront. Friends of Waterfront Park will manage and program the new space in partnership with the city.

“It’s not only a place for children to play but a big step forward in creating a downtown that works for residents of all ages,” say downtown parents Emily and Michael George, who helped shape the playground design.

Located between Pike and Union Streets next to the Seattle Aquarium, Pier 58 was designed for kids, caregivers, and accessibility. There’s plenty of seating, clear sightlines, and nearby public restrooms, which opened earlier this spring. Architectural lighting built into the railings, play structures, and seating areas keeps the space lit at night.

The project arrives as downtown traffic returns, with an estimated 15 million people projected to visit the redeveloped waterfront each year once complete. Pier 58 follows the debut of Overlook Walk, which opened last fall and drew more than 50,000 visitors in its first week.

Together, these projects are milestones in Seattle’s $800 million waterfront rebuild — a transformation more than 15 years in the making. It began with the viaduct teardown, followed by seawall reconstruction, new bike paths, a pedestrian promenade, and now, expanded public parks.

“Our goal was to create a waterfront for all — accessible, safe, greener and welcoming,” says Angela Brady, director of the Office of the Waterfront, Civic Projects and Sound Transit. “That vision has become a reality, and we’re excited to invite everyone to experience this space together.”

The city will mark the opening with a free, family event from 4-8 p.m. on Friday, July 25, featuring local mascots Marine-themed costumes are encouraged.
