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):

We solicit bids for an on-call contract for offshore repairs that require a floating derrick barge every two years. Once awarded to a contractor, the work is completed on an as-needed basis. We also solicit bids for an on-call contract for painting work. Other contract work is designed and bid out to private contractors.

Traction tires are a special type of tire

manufactured with at least 1/8 of an inch tread. Traction tires are usually marked with a mountain/snowflake symbol, the letters M+S or “All Season.”

Carry chains, practice before leaving

Requiring chains keeps traffic moving during storms rather than closing a pass or roadway.
