The Washington State Transportation Commission has approved across-the-board ferry-fare increases that will raise the cost of passenger and vehicle fares.

A 2 percent increase on passenger fares and 3 percent increase on vehicle fares will take effect on Oct. 1.

The October increase amounts to an additional 15 cents for walk-on fares, 15 cents for small vehicles, and 65 cents for vehicles between 22 and 30 feet in length on the Bainbridge Island-Seattle route.

Another increase is slated for May 1, 2014. Passenger fares will rise by 2 percent, and vehicle fares will also go up, with a 2.5 percent increase.

The commission approved the fare changes after a final hearing July 30. Officials said the increases were needed so the state could meet the ferry-fare-revenue target set by the Legislature in the recently enacted 2013-2015 transportation budget.
