Ferry terminal maintenance

Find the status of ferry terminal maintenance projects and learn about upcoming projects.

We contract out roughly $3 million in terminal maintenance construction each year. These contracts address short-term issues identified through facility inspections prior to larger replacement projects. We also conduct a large portion of maintenance work with in-house staff and by working with various WSDOT regions.

Proper terminal maintenance helps prevent ferry service disruptions. The contracted work covers the following (see diagrams for visuals of terminal structures and components):
