The seasonal rates will increase for drivers on the Seattle to Bainbridge Island and Seattle to Bremerton routes from $13.15 to $16.40.
It will also cost more to travel to the San Juan Islands. A round-trip ticket from Anacortes to Friday Harbor will cost $57.35. That’s up from $42.55.
The surcharge helps to pay for increased operation from more traffic from May through September.
Passenger fares are not affected.
