Colman Dock is Washington State Ferries’ largest and busiest ferry terminal. Key elements of the project included replacement of the timber trestle with a new concrete and steel trestle, reconfiguring the dock layout, replacing the vehicle transfer span, and the overhead loading structures of the northernmost Slip 3, and mitigation for an additional 5,200 SF of overwater coverage. The updated layout was designed to address safety concerns and operational inefficiencies to preserve Colman Dock as a safe and reliable transportation hub. The new structure is designed for 1,000 year seismic event.
