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.
