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.

Viaduct demolition

  • Viaduct demolition is underway

  • One lane of Alaskan Way will be open in each direction adjacent to active construction. Elsewhere, two lanes will be open in each direction.
  • There will be no fixed bicycle/pedestrian detours during construction, as the work zone will be frequently moving up and down the structure.
