This document is a collection of technical drawings, pile driving records, and project documentation for the Yaquina Bay Bridge Dolphin Replacement project, undertaken by the Oregon State Highway Division in Lincoln County. The project involves replacing dolphins (structural support elements) for the existing bridge, with detailed engineering drawings for Pier 2 and Pier 3 of the bridge. The work was performed under Contract No. 8449, with pile driving activities conducted in late 1996, specifically from December to January, using an ice vibratory hammer and jet-assisted driving technique.

The project documentation includes comprehensive records of pile driving operations, with detailed logs tracking each pile's delivery length, driven length, penetration depth, and completion date. The driving was performed on Piers 2 and 3 of the Yaquina Bay Bridge, with 33 piles driven on Pier 3 and multiple piles on Pier 2. Technical challenges were noted, including some piles being classified as "bad piles" and requiring replacement. The project involved using HP 12x53 steel piles, with zinc anode plates added to some piles for corrosion protection. Additional work included installing navigation lights, ladders, and other structural elements on the bridge's dolphins. The total cost for Pier 3 pile driving was documented as $28,273.00.
