REPORT SUMMARY
UNDERWATER INSPECTION
The substructure units inspected at Bridge No. 86502, Piers 1 and 2, were generally found to be in good condition with no defects of structural significance. Coating failure was typical on piles from 1 foot above the waterline to the channel bottom. The channel bottom around each had a 1 foot deep scour pocket around each of the piles.
(A) The piles exhibited 80 percent coating failure from 1 foot above the waterline to the channel bottom.
(B) A 3 foot diameter scour pocket was noted around each pile approximately 1 foot deep.
(C) Timber debris up to 8 inches in diameter was noted along the length of Pier 2.

The routine underwater inspection of Bridge 86502 (Eastwood Ave SE over the South Fork Crow River) was completed on June 22, DAY, 2016. 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. The inspection utilized commercial dive equipment and techniques (SSA and/or SCUBA) 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 two piers with four CIP piles each. According to the bridge inventory or design drawings, Piers 1 and 2 were founded on CIP 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.
