Travel times for riders on the Bainbridge Island ferry from Seattle will be changed for a two-week period in early January to accommodate continuing construction at Colman Dock.

Officials with Washington State Ferries have announced that all trips between Colman Dock and Bainbridge Island — as well as sailings to Bremerton — will follow a temporary sailing schedule that starts Saturday, Jan. 4.

The new schedule will run until Monday, Jan. 20.

During the temporary sailing schedule, WSF officials said all Bainbridge Island and Bremerton sailings will operate out of a single slip, and some crossings may take longer to prevent more than one ferry from arriving or departing the slip at the same time.

Most departure times will shift between five and 30 minutes, but sailings later in the evening may shift as much as one hour, according to WSF.

WSF said it is working with Kitsap Transit to maintain as many bus connections as possible that work with the temporary sailing schedule for ferry riders.

Operating from one slip will give WSF’s contractor on the Colman Dock project more room to finish critical work on the north side of the dock. This work includes removing the remainder of the old terminal, taking out the old wooden piles and driving in new steel piles that will support the deck for the new passenger terminal.

“We know that schedule changes have an effect on our customers’ daily lives and we do not make these decisions lightly,” said WSF Terminal Engineering Director David Sowers.

“As with any construction project, sometimes work takes a little longer. Operating from one slip for this period provides more space for the contractor to efficiently finish critical work on the north side of the dock,” he said.

WSF said ferry riders should check out the schedule changes before they go into effect, and plan ahead for different departure times, which may result in heavier traffic at ferry terminals.

Construction to replace the Colman Dock terminal began in August 2017 and will continue until 2023.
