There was up to 8 feet of flowing water in the river during this <br />investigation. Piers 2 and 3 were submerged and Pier 4 was at the water line. Spans 2 and 3 were inspected with the aid of binoculars <br />from near Piers 2 and 4. A complete routine inspection was performed on all of the visible elements by walking on and about the <br />structure. <br />Due to the substantial depth at Piers 2, 3 and 4, their condition below the water level can be established only through a diving inspection. <br />An underwater inspection was performed on 08/05/2019 by the Underwater Investigations Team. All identified defects from that <br />inspection have been incorporated into the condition states of the respective elements and have been described in the element or defect <br />notes. Refer to the 08/05/2019 underwater inspection report for further detail. <br />MISCELLANEOUS <br />A new routine map view photo was added during this investigation. See Photo 1. <br />SUBSTRUCTURE <br />There are logs and debris lodge against the upstream side (right) of Piers 2 and 3. See Photo 2. <br />There are trees growing below the structure in Span 4 near Pier 4 and below the cap at Pier 5 on the left. See Photos 3 and 4. <br />SAFE LOAD CAPACITY <br />The load rating for this structure is being reviewed by SMI Ratings Branch under work request number 11691. An updated Load Rating <br />Summary will be archived when this review is complete. The current rating is based on BDS computer output dated 11/29/1979. While <br />this report does not include a check of that analysis, it does verify that the structural conditions assumed in that rating have not changed <br />significantly. <br />INSPECTION COMMENTARY <br />1 - FreshWater TypeB - Routine UWDive Type <br />Next UWI 08/05/2024UWI Frequency months 60UWI Required Y Last UWI 08/05/2019 <br />- NOT APPLICABLE FOR THIS BRIDGE. <br />CONDITION INFORMATION <br />SPECIAL INSPECTION INFORMATION
