The abutments were <br />outside of the water. The inspection was limited to the deck and portions of the superstructure and substructure above the water line and <br />portions of the bridge visible from the canal banks. A return visit will be scheduled when the canal is dewatered. <br />The submerged portions of Piers 2 and 3 were inspected by the Caltrans Underwater Inspection Team. The most recent underwater <br />investigation was performed on 05/28/2020. All identified defects from that inspection have been incorporated into the condition states of <br />the respective elements and have been described in the element or defect notes. Refer to the 05/28/2020 underwater inspection report <br />for further detail. <br />DECK AND ROADWAY <br />There are some transverse cracks up to 0.125 inches wide and spaced as close as 4 inches on center in the AC approach roadway at <br />both abutments.
