Ballast Island sign installation on Colman Dock
May 8, 2026
Colman Dock has a new interpretive installation telling the story of Ballast Island, a place of importance to local Coast Salish tribes and Seattle’s history. We designed the sign in collaboration with Washington State Department of Transportation and Washington State Ferries. The sign structure holds five vertical feet of actual ballast unearthed during the construction of Colman Dock.
