Seattle's Central Waterfront is going to be a busy place over the next several years, with multiple construction projects underway. To make it easy for you to stay up to date on what's going on and what's ahead, we've compiled project information all in one place. This site provides general information about current and future public projects. For additional project details, visit the project websites, which can be found in the “Contact Us” page.

Spring 2022

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 Seattle Terminal and Cameras.
  • The first section of the new terminal building opened to the public in September 2019, with a limited capacity of 65 seats. Passengers should plan to arrive about 15 minutes before departure to avoid standing in line for long periods of time.
  • The final two-thirds of the terminal building is expected to open in summer 2022 and the remainder of the project in spring 2023. These dates take into account the recent concrete delivery strike in the Puget Sound area, and assume that we will be able to receive necessary concrete as planned. Our contractor has resequenced work these past several months to work around the strike. WSDOT maintains a weekly project impacts page related to the strike on this web page.
