3 UNDERWATER INSPECTION REPORT SUMMARY The substructure units inspected at Bridge No , Piers 1 and 2, were found to be in good condition with no defects of structural significance observed. The channel bottom appeared stable with no changes since the previous inspection. INSPECTION FINDINGS (A) The channel bottom material consisted of gravel and 1 foot diameter and smaller cobbles, with no appreciable probe rod penetration. (B) The concrete was in smooth and sound condition. RECOMMENDATIONS (A) Reinspect the submerged substructure units at the normal maximum recommended (NBIS) interval of sixty (60) months.

4 UNDERWATER INSPECTION 1. BRIDGE DATA Bridge #: Feature Intersected: Facility Carried: District: County: CANNON RIVER CSAH 11 District Rice Bridge Description: The bridge consists of three spans of multiple steel stringer bridge supporting a reinforced concrete deck. The superstructure is supported by two reinforced concrete abutments and two reinforced concrete piers. The pier and abutment footings are founded on steel H-piles. The piers are labeled Piers 1 and 2 starting from the west end of the bridge. 2.

6 UNDERWATER INSPECTION INSPECTION PROCEDURES The routine underwater inspection of Bridge (CSAH NO. 11 over the Cannon River) was completed on May 26, The underwater inspection was conducted from shore. The inspection was conducted by a team consisting of a PE-Diver with a valid MnDOT Team Leader certification, a backup diver and a dive tender. Due to waterway conditions at the time of inspection, the inspection could be accomplished by wading in accordance with OSHA regulations. Profiles were taken along the upstream and downstream faces of the bridge and around the periphery of substructure units to determine the presence, location and area of scour. The bridge elements inspected consisted of Piers 1 and 2. According to the bridge inventory or design drawings, Piers 1 and 2 were founded on rectangular spread footings with steel H-piles. Inspection procedures followed FHWA guidance and the MnDOT Bridge and Structure Inspection Program Manual with channel bottom probing to search for foundations. The routine underwater inspection frequency is recommended to remain at a maximum of 60 months based on those findings and risk factors. Also, inspection procedures should continue to follow the above approach and standard guidance with 100% Level I and 10% Level II intensity efforts. Page 6 of 18
