Status

March 2015

  • Construction to retrofit the Vashon ferry terminal is scheduled to begin in June 2015.
  • Thank you to everyone who joined us at community meetings on March 10 and 12. View the meeting materials  to learn more about what to expect during construction, including modifications to the ferry schedule and operations.
  • Meeting materials: Slideshow presentation (pdf 1.7MB), Southworth meeting handouts (pdf 2.8MB), Vashon meeting handouts (pdf 2.8MB).

WSF will upgrade the entire Vashon ferry dock. This framework of timber that serves to support the holding lanes, and pedestrian and vehicle lanes to/from the ramps to the ferry.

Why is WSDOT replacing these structures?
The Vashon ferry terminal provides a critical link between Vashon Island, the Seattle mainland and the communities west of Puget Sound. The existing Vashon ferry dock was constructed in 1957 and is vulnerable to earthquakes.  

The project will bring the entire dock up to current seismic code and allow access to and from the island in the event of an earthquake.

The End Result
This project will retrofit the existing ferry dock by placing seismic braces at 10 critical locations along the dock and replacing about 200 feet of timber trestle with concrete supported by steel piling.

In the event of an earthquake, the main transportation corridor for Vashon Island residents will be better protected. 

Project Benefits

  • Improve Reliability: In the event of an earthquake, both terminals on Vashon Island are at risk. It’s critical that the island’s main terminal be upgraded immediately.
  • Improve Safety: The project brings the dock up to seismic, mechanical and electrical codes.

What is the project timeline?

  • April 2015: Advertise project.
  • June 2015: Begin construction.
  • April 2016: Complete construction.

Financial Information

The total project cost is $15 million. Funding is provided through a mix of federal grants and state funding.
