What's Happening Now?
Project Update (June 2022): Crews have one day of work between the South and Delridge substations, which will require a clearance on the energized lines and additional coordination with other parties. The remaining Delridge to Duwamish substation work is 60% complete. This portion will be completed by the end of the year.
