Construction photos

A wooden platform is shown underneath the First Avenue South Bridge. A crane sits on top of the wooden platform. Crews built a “trestle,” or temporary work platform, to extend work into the Duwamish River and hold equipment, such as a crane. View more photos of the outfall structure .
A steel box is shown underground with crew members inside, digging and installing a pipe. An excavator works from above ground to remove soil. Crews excavated soil to begin installing 60-inch pipe that will connect the treatment station to the new outfall structure. View more photos of the conveyance pipeline .
