The Puyallup River Bridge structure consists of a concrete girder portion and a segmental cast-in-place portion. The pre-stressed concrete girder bridge consists of six piers and five spans, while the cast-in-place segmental bridge consists of four piers and four spans. The longest spans are 445 feet on the cast-in-place segmental portion, while the shortest span is 109 feet on the pre-cast girder bridge. The deck is cast as an integral part of the cast-in-place box girder.
