Ferry Dock Road
If you walked onto the ferry in Mukilteo, and are hopping into a car in Clinton, you'll meet your ride on Ferry Dock Road, just up from the pier, on the left. The road wasn't actually designed for that purpose, but they're fixing it. Construction starts in the middle of February.
Want more information? Here's a good place to look: WSDOT Clinton Project. Better yet, attend the pre-construction public meeting, which will be held Wednesday February 6th, from 5 to 7 PM, at the Clinton Community Hall.
