A Port of Tacoma contractor drove the last of 795 concrete piling Monday into the Blair Waterway to support a new wharf. The $46 million wharf is part of a facility planned for the 83-acre former Kaiser Aluminum property on the east side of the Blair. This phase of construction was the first of more than $800 million in redevelopment planned along the Blair-Hylebos Peninsula between now and 2012. Future plans include a relocated and expanded terminal for Totem Ocean Trailer Express and a new marine terminal for NYK Line. The plans also include substantial road and railway improvements to serve these terminals as well as a privately-owned terminal planned by SSA Marine and the Puyallup Tribe of Indians.
