The abutments were outside of the concrete lining and <br />the superstructure and soffit of Spans 1 and 3 were inspected from the canal banks with the aid of binoculars. The soffit of Span 2 was <br />visually observed from the deck with the use of truck mirrors. <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 02/13/2018. 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 02/13/2018 underwater inspection report <br />for further detail. <br />MISCELLANEOUS <br />New routine photos were taken and a new routine map view photo was added during this investigation. See Photos 1 to 4. <br />DECK AND ROADWAY <br />The AC approach pavement at both abutments is deteriorating. There are pattern cracks up to 1 inch wide and spaced as close as 4 <br />inches on center at both approaches. At Abutment 1, there is a section up to 12 feet wide x 18 inches long where portions of the AC are <br />missing in the northbound lane along the bridge interface. (See Photo 5). At Abutment 4, there is a pothole up to 20 inches wide x 6 <br />inches long in the southbound lane near the fog line.
