The final concrete pour for the Hood Canal Bridge started at 5:22 a.m. and wrapped up about 11:20 a.m. June 27, 2008 at Concrete Technology Corporation (CTC) in Tacoma. The 430 cubic yards placed for the top slab on pontoon W brought the total concrete used in pontoon construction to more than 29,000 cubic yards. That’s enough to pave 12.3 miles of two-lane highway, roughly from Seattle to Renton, in one foot of concrete.Construction of pontoons U and W – which measure 360 feet long, 60 feet wide and 18 feet tall, and 325 feet long, 60 feet wide and 18 feet tall, respectively – marks the end of the fourth and final pontoon cycle. It is also another milestone reached on the way to the east-half bridge replacement process scheduled to occur during the six-week Hood Canal Bridge closure in May-June 2009.
