The Washington State Department of Transportation (WSDOT) and Washington State Ferries (WSF) are proposing to upgrade Colman Dock. Colman Dock is located on Alaskan Way in downtown Seattle. The dock provides ferry services for the WSF fleet serving Seattle, Bremerton, and Bainbridge Island. The facility also provides passenger ferry services for King County’s ferry routes to Vashon and West Seattle.

  • Replacing aging timber piers
  • Re-orienting the existing overwater dock coverage areas
  • Constructing a new terminal
  • Creating a new entry building fronting Alaskan Way

WSF’s long-term plans include retail spaces between the entry building and terminal and a new passenger-only facility for King County’s passenger ferries. WT provided MEP Cost Review and Negotiation Services for this project.
