Ferries - Seattle Multimodal Terminal at Colman Dock Project

Project news

  • Big changes for walk-on customers: We moved all services to the first part of the new terminal building located next to the old terminal building. The old building is now closed and is being demolished. There are no changes to ferry access for drive-on customers. 
  • Stay informed about the latest changes and sign up for rider alerts.
  • Viaduct demolition is nearly complete! There are still lane closures and slowdowns near Colman Dock. You can avoid significant travel delays to and from the ferry terminal by riding a bike, walking or taking public transit.

Overview
Washington State Ferries is replacing the aging and seismically vulnerable parts of Colman Dock in Seattle in order to maintain its critical role as a regional multimodal transportation hub.

The End Result

Key project elements include:

*While avoidance and minimization of new overwater coverage was a key goal of the project, the new facility will increase the overwater footprint by approximately 5,200 square feet. Mitigation for this increase in overwater coverage was achieved by removing overwater coverage from a neighboring pier owned by WSDOT.

Project Benefits
The project will:

  • Ensure that the Colman Dock facility can continue to provide safe and reliable ferry service between Seattle and communities in Kitsap County and the Olympic Peninsula
  • Improve safety by meeting current seismic standards
  • Reduce conflicts between vehicles, bicycles and pedestrians and improve operational efficiencies
  • Improve circulation and accessibility for people walking, biking and driving. 
  • Remove 7,400 tons of creosote-treated timber piles from Elliott Bay
  • Open up an area of shoreline and near-shore habitat
  • Provide stormwater treatment for all new and replaced areas of the trestle
  • Provide opportunities for remediation of contaminated sediments

Timeline

  • 2012-2015 – Environmental process/preliminary design
  • 2015-2017 – Final design and permitting
  • Summer 2017-2023 – Construction
    • Summer 2019 – New passenger-only ferry terminal opens on south side of dock

Construction will continue until 2023 and the terminal will remain open throughout construction.

While the terminal and all ferry operations will be available and maintained throughout construction, customers can expect changes to how vehicles, passengers and bicycles load and unload.

WSF will continue to coordinate closely with other Seattle waterfront projects, including  Waterfront Seattle, and Alaskan Way Viaduct Replacement Program throughout construction.


Disadvantaged business enterprise (DBE) program
WSF has chosen the General Contractor/Construction Manager delivery method for the project. Hoffman-Pacific, a Joint Venture, was selected as the GC/CM in fall 2015 and has committed to maximizing opportunities for DBE firms. WSDOT has established a DBE goal of 12% of the project’s Maximum Allowable Construction Cost (MACC).

Funding

  • $455 million in federal, state and local funding has been appropriated for this project.
  • King County provided funding for replacement of the passenger-only ferry facility.

With $455 million in secured funding, WSF will replace the seismically-vulnerable elements of the facility to preserve Colman Dock’s core functions. This budget also funds the entry building and pedestrian plaza, bicycle facility and a new vehicle transfer span.
