Demolition of old Colman Dock terminal underway

New structure will be built to withstand major earthquake

Historic changes are underway on the Seattle waterfront.

This month the 53-year-old Colman Dock ferry terminal is being torn down to make way for the new terminal. Washington State Ferries is working to replace the seismically vulnerable structure.

In mid-September, Washington State Ferries moved all ticketing and operations for walk-on passengers into the first section of the new terminal building to the south. When complete, the two sections will be connected to form the new terminal. The project is anticipated to be complete in 2023.

One of the final pieces of the Alaskan Way Viaduct at Marion Street came down in early September, including the old Marion Street pedestrian bridge to the ferry terminal.

A temporary pedestrian bridge has been built between Colman Dock and the existing pedestrian bridge on a new route along Columbia Street and Western Avenue. This temporary bridge will be in place until the City of Seattle builds a permanent pedestrian bridge on Marion Street, scheduled to open in 2023.

In addition to building a safer and structurally sound terminal, the Colman Dock project will provide environmental benefits by removing 7,400 tons of creosote-treated timber piles from Elliott Bay, adding stormwater treatment, opening up habitat on the shoreline, and remediating contaminated sediments.  

PSRC has provided $32 million in regionally managed federal funding to Washington State Ferries for the Colman Dock project.
