REPORT SUMMARY
UNDERWATER INSPECTION
The substructure units inspected at Bridge No. L5733, the East and West Piers, were found to be in good condition with no defects of structural significance observed. The stone masonry was in good condition with only minor hairline cracks observed in the mortar joints at random locations. The top of the footing at the West Pier was partially exposed from the west face quarter point, around the upstream nose, and to the midpoint along the east face. No vertical footing exposure was noted. The channel bottom appeared stable with no significant scour observed and with minimal changes since the last inspection.
(A) The channel bottom material consisted of sand infilling at the downstream end of both piers allowing up to 1 foot of probe rod penetration.
(B) The channel bottom material consisted of riprap 1 to 2 feet in diameter at the upstream nose and 6 to 8 inch diameter riprap and sand along both sides of the West Pier.
(C) The channel bottom consisted of riprap 1 to 4 feet in diameter at the upstream nose and 6 to 8 inch diameter riprap and sand along both sides of the East Pier.
(D) The top of the footing was partially exposed on the West Pier, from the quarter point along the west face around the upstream nose, and to the midpoint along the east face. No vertical face exposure was present.
(E) The stone masonry was in good condition with minor hairline to 1/8 inch (maximum) wide cracks observed in the mortar joints at random locations on both piers.
(F) A light accumulation of steel debris was observed scattered on the channel bottom around both piers.
(G) A light accumulation of timber debris observed around the downstream quarter of the west face of the West Pier, with up to a 1 foot diameter.

The routine underwater inspection of Bridge L5733 (CP Rail over the Mississippi River) was completed on October 6, 2016. The underwater inspection was conducted from a 21 foot boat. 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 stone masonry block piers. Due to unavailable design plans, the foundations for the West and East Piers are unknown. 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.
