Smaller rock pockets are <br />located at the upstream and downstream noses of the piers. The most significant voids are located on the Span 2 side of Pier 2 near <br />the right side of the original structure. Based on a field comparison of Photos 10 through 16 from the 02/2019 report, this condition <br />has not changed. <br />The concrete from the widened portions of the abutments overlapped the abutments of the original abutments. <br />Minor to moderate abrasion is present throughout the abutment faces and wingwalls. Coarse aggregate is visible throughout the <br />abutments. The majority of the aggregate appeared to be sound but rock pockets have formed and encompass sections that are <br />typically up to 6 inch in diameter and are predominantly located at the corners of the bridge. <br />Based on a field comparison of Photos 17 through 26 from the 02/2019 report, this condition has not changed. <br />Element 256 accounts for the paved concrete at the corners of the abutments that was present on the embankments and at the base <br />of the widened portions of the abutments. <br />The concrete at the base of the original portions of the abutments did not warrant element 256. <br />Erosion was present above and behind the slope protection at the right side of Abutment 4. <br />At the top of the embankment, an erosion gulley approximately 5 feet in width x 2 feet in depth was present. Concrete sack protection <br />has been placed at the top of the concrete slope protection, but the concrete sacks appeared to be ineffective. <br />Near the base of the embankment, a void was present behind the slope protection. The size of the void could not be determined. <br />Due to the void a section of concrete approximately 6 feet x 5 feet has settled approximately 2 to 3 inches and shifted approximately <br />1 inch. <br />Based on a field comparison of Photos 26, 28 and 29 from the 02/2019 report, this condition has not changed.
