Constructing the Duwamish substation for Seattle City Light, South Park, Seattle, Washington, 1955, installing a large transformer. (May be technically on county land along the river outside city limits, I'm not sure, there's a bit of a patchwork of jurisdictions there.) This is near where Hamm Creek enters the Duwamish from its right bank.
