This condition is visible on the exterior girders. <br />There is no defect element to capture this deterioration and so it is included here. <br />Due to high water levels this element was not inspected during this investigation. <br />Non-Routine Inspection Element Notes: <br />UWI (05/27/2020): See Table 3 of the report from AECOM. There are 15.4 lineal feet (5 meters) of girder spalls with associated <br />exposed reinforcing with section loss. A hands-on inspection of exposed reinforcing steel was not possible by the diver. <br />JOINT/APPROACH/RAIL ELEMENT INSPECTION RATINGS AND NOTES <br />JOINT - APPROACH - RAIL <br />(330-1000) Corrosion <br />Element DescriptionElem <br />No. <br />Env Total <br />Qty <br />Units <br />CS 1 CS 2 CS 3 CS 4 <br />Qty in each Condition StateDefect/ <br />Prot Defect <br />There is surface rust on the face of the bridge rails where the rail and the paint coating have been scraped along the full <br />length of the bridge and where the paint system has failed. (See Photo 7 dated 06/08/2022). This condition has been <br />previously reported and no significant changes were noted. <br />Photo 1 <br />Vehicle impact damage to the right approach rail at Abutment 1 <br />Photo 2 <br />Vehicle impact damage to the left approach rail at Abutment 4 <br />JOINT/APPROACH/RAIL PHOTOGRAPHS
