Summer 2021

Colman Dock Multimodal Terminal Project

  • Washington State Ferries is replacing the aging and seismically vulnerable parts of Colman Dock in Seattle to maintain its critical role as a regional transportation hub. Project construction began in 2017 and will continue through early 2023. The terminal will remain open throughout construction.
  • The passenger-only ferry facility is open for Kitsap Transit and the King County Water Taxi. This dock is at Pier 50, adjacent to the south end of Colman Dock, which is Pier 52.
  • For the latest information on access to and from Colman Dock, including accessible paths, driving, biking, and walking, please visit Getting to Colman.
  • The first section of the new terminal building opened to the public in September 2019. This first section of the terminal has limited capacity and 65 seats. Passengers should plan to arrive about 15 minutes before departure to avoid standing in line for long periods of time.
