The inspection of the remainder of the element and all other elements is the responsibility of the routine inspection. This structure was inspected from the west bank using wade, float, and probe inspection techniques.

SUBSTRUCTURE All submerged elements were covered with a thin layer of growth which could easily be removed by the inspector's gloved hands. This condition allowed for a 100% Level I inspection and a minimum of 10% Level II inspection of the submerged portions of the elements. For reference purposes, the height from waterline to the top of rail was 13.0 feet at Bent 3, Column 5 at 1140 hours on the day of this inspection.
