Closing the Seattle Seawall superstructure at Waterfront Park

Looking north from vicinity of Pier 55

Construction activity continues at the Elliot Bay Seawall Project . The wall structure is nearing completion along Waterfront Park, while Improved Soil Mass jet-grouting continues at the south end of the current excavation zone.

This quick post provides a glimpse of current status and shows the final steps required for completing the assembly of the wall superstructure. With the Z-panel modules in place there’s still the need to tie everything together and close the wall. This is done with more steel and concrete.



Waterfront Seattle’s March 19th weekly progress update highlights this step. Our prior few posts show the wall installation sequence. Once complete, underground utilities are reinstalled and the excavation is backfilled. Then time to pave the new Alaskan Way.
