3 UNDERWATER INSPECTION REPORT SUMMARY The substructure unit inspected at Bridge 2796, Pier 12, was in satisfactory condition below water with no structural significant defects observed. The channel consisted of tightly packed riprap and large concrete debris at the downstream nose. Gaps were observed in the steel sheeting at the east and west upstream quarter points along with a void between the horizontal C- channels and vertical sheathing. The steel sheeting was in fair condition with surface corrosion throughout and torch cut holes at random locations. The steel sheeting was slightly separated from the concrete. INSPECTION FINDINGS (A) The channel bottom material, within 10 feet of the substructure unit, typically consisted of tightly packed riprap from 1 foot to 3 feet in size. Along the downstream end, the channel sloped up at a steep angle and was located approximately 3 feet below the waterline, the downstream channel bottom material consisted of cobbles of less than 6 inches in size, riprap from 1 foot to 4 feet in size, and large concrete debris. (B) Gaps in the lines of construction (not at interlocks), were observed in the steel sheeting at the east and west upstream 1/4 points with maximum widths located at the channel bottom. The west gap measured 15 inches in width and had a maximum penetration of 6 inches. The east side gap measured 36 inches in width and had no penetration. (C) A void between the horizontal C-channels and the vertical sheeting was observed at the east side upstream 1/4 point of the pier at 3.0 feet below the waterline with a height of 2.5 feet and 3.5 feet of maximum penetration. (D) The steel sheeting was in fair condition with a uniform 1/8 inch layer of surface corrosion extending from the top of the sheeting to the channel bottom. Torch cut holes, 3 inches in diameter observed at random locations. (E) The steel sheet piling was slightly separated from the concrete around the base of the pier for a length of approximately 20 feet along the east and west sides. (F) The topside concrete surface within the sheeting was sound, however, gaps/cracks up to 1 foot maximum width were observed on both east and west sides of Pier 12. RECOMMENDATIONS (A) Reinspect the submerged substructure unit at the normal maximum recommended (NBIS) interval of sixty (60) months.

4 UNDERWATER INSPECTION 1. BRIDGE DATA Bridge #: Feature Intersected: Facility Carried: District: County: 2796 MISS R; BNSF STS CEDAR (10TH) Metro Hennepin Bridge Description: The superstructure consists of an open-spandrel reinforced concrete arch supporting a reinforced concrete deck. The superstructure is supported on two reinforced concrete abutments and 19 reinforced piers numbered from the west end of the bridge. Only Pier 12 is located within the channel. The pier is supported on a rectangular footing supported by steel piles. 2.

6 UNDERWATER INSPECTION INSPECTION PROCEDURES The routine underwater inspection of Bridge 2796 (10th Avenue over the Mississippi River) was completed on July 7, 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 three reinforced concrete piers. According to the bridge inventory or design drawings, Pier 12 was supported by rectangular footing founded on 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 routing 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 19
