Seawall reinforcement work completed in March 2023
March 6, 2023
Crews will repair a section of the Dockton seawall that was damaged in January 2023 during a king tide. The work is scheduled to start on Thursday, March 9 at 7:00 a.m. and end Saturday, March 11 at 4:00 p.m. Dockton Road will be reduced to one lane of alternating traffic at the repair site, around the clock. In addition, Highland Road SW will be fully closed between Tramp Harbor Road SW and Dockton Road SW to help provide a safe work area for our crews by preventing traffic from entering the work zone. Local access, emergency vehicles and buses will be allowed through. There is no posted detour. A suggested alternate route is Tramp Harbor Road SW to/from Dockton Road SW.

About the repairs
The bottom section of a part of the wooden wall just north of Highland Avenue SW will be patched with new wood. We also will reinforce this section with concrete blocks to help prevent further damage.
King County will continue to monitor the entire length of the Dockton seawall. We will return as needed to make any additional repairs.
A king tide causes water to flow over the roadway on SW Quartermaster Drive. The king tide shown above also damaged a section of the Dockton seawall just north of Highland Avenue SW in January 2023.
