Issues: 3-span prestressed concrete girder bridge; noted that the joint openings at each end bent are significantly wider at the bridge deck surface, and get narrower with depth; one possibility that was mentioned was settlement of the slope protection causing rotation of the end bents Action Item: Review the contract plans to determine the detailed formed joint opening size; check the adequacy of the opening size for the bridge length Issues: Noted erosion under one end bent cap corner; also noted that the distance from the end of the end bent cap to the first HP pile was approximately 6 feet (which matches the details in the contract plans); this distance is typically around 1.5 feet Issues: The 3-bar metal rail had been impacted; noted that the concrete break-out that occurred around the rail post was very similar to that predicted in ACI-318 Appendix D
