The abutments were dry and <br />the soffit and superstructure were observed from the canal banks. A complete routine inspection was performed on all of the visible <br />elements by walking on and about the structure. <br />The submerged portions of Pier 2 are inspected by the Caltrans Underwater Inspection Team. The most recent underwater investigation <br />was performed on 02/14/2018. All identified defects from that inspection have been incorporated into the condition states of the respective <br />elements and have been described in the element or defect notes. Refer to the 02/14/2018 underwater inspection report for further detail. <br />NUMBERING CONVENTION <br />The numbering system used on the as-built plans for this structure is reversed from the convention employed by Structure Maintenance <br />& Investigations. This report and all subsequent reports will follow the SM&I numbering convention with Abutment 1 designated as the <br />south abutment. <br />MISCELLANEOUS <br />New routine photos were taken and a new routine map view photo was added during this investigation.
