Welcome to the Seattle waterfront construction information site!

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.

Current construction activity


Status updates

Summer 2021

Colman Dock Multimodal Terminal Project

  • New WSDOT website and Colman Dock terminal project pages
  • Visitors to the WSDOT website will notice a big difference. We launched a new website on Nov. 7 -- its first major overhaul in more than 15 years.
  • The URL has stayed the same, https://wsdot.wa.gov/, but the site is redesigned to focus on the needs of our 75,000 daily visitors. The new site is mobile and user-friendly with improvements for accessibility to serve everyone, on any device.
  • Bookmark the Colman Dock Project where you’ll find general information on the project, updates, maps, and more.
  • 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. This first section of the terminal has 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.
