From shipyard to port. Massive tugs gently coax a gentle giant of a caisson from the Port of Tacoma to its final resting place just south of the existing bridge. Above the water line can be seen corrugated steel panels, which are the caisson's "steel skin," providing a watertight environment for placing concrete in the dry. Favorable tides, knowledgeable mariners and a tremendous amount of planning contributed to a smooth and successful voyage. Summer 2003
