See Photo 2 dated 06/25/2018. It is assumed the water in the aqueduct is not responsible <br />for this condition and so this condition does not warrant a defect at this time. Compared to previous photos, there has been no <br />significant change. In addition, on the Span 1 side the top of the footing is exposed its entire width. The condition of the Span 1 side <br />of the footing was not confirmed during this investigation due to the restricted access from the homeless encampment. <br />There were no significant defects noted. <br />The quantity includes the monolithic RC wingwalls at each abutment. <br />Abutment 1 and 3 were not inspected during this investigation due to the presence of a homeless encampment below these spans. <br />This quantity includes those piles exposed under Pier 2 and the piles not visible for inspection. <br />There were no significant defects noted. <br />Span 2 is cantilevered with a suspended span. There is a visible sag in Span 2, estimated to be 2 inches in displacement, noticed by <br />sighting down the bridge rail. No defect is warranted at this time. <br />There is a vertical crack up to 0.05 inches wide and is approximately 4 feet long on the interior face of Girder 1 near Pier 2 on the <br />Span 2 side. There is a failed patch over this condition which makes it difficult to accurately quantify the width. (See Photo 3 dated <br />06/06/2022). <br />There is a hairline diagonal crack in the exterior face of Girder 4 in Span 3 near Pier 3. This crack is up to 5 feet long and has light <br />efflorescence. (See Photo 2 dated 06/25/2018). This condition was not confirmed during this investigation due to the restricted access <br />from the homeless encampment below Span 2 at Pier 3 and near Abutment 4. <br />The elastomeric bearings at Pier 2 are beginning to bulge and crack. (See Photo 4 06/06/2022). This condition has been previously <br />reported and no significant changes were noted.
