Foundation of Seattle’s waterfront
The Seawall Project is constructing a replacement seawall along Seattle's waterfront to protect critical infrastructure and utilities while enhancing the habitat through this area. The new seawall meets current seismic standards and will last more than 75 years, serving as the foundation for projects transforming Seattle's future waterfront.
Construction begins between Pine and Pike streets
Construction work between Pine and Pike streets is underway. This work is scheduled to be complete in mid-2017. The Seattle Aquarium and other waterfront businesses will remain open and access will be maintained at all times. Click here more information about what you can expect in the coming months.
Work between Madison and Marion streets continues and is scheduled to be complete by fall 2016. Businesses in this area will be open and accessible and can be accessed via the multi-use path on the west side of the viaduct and by short bridges across the construction zone. Please follow the direction of flaggers and signage to access your destination.

September 29, 2016 – Construction Update:
While face panels continue to be installed in some areas, we have moved ahead placing quarry spalls before installing marine mattresses. Quarry spalls are small rocks that are poured into the excavated area before marine mattresses are laid down. Click here for this week's construction update.
