REPORT SUMMARY

UNDERWATER INSPECTION

The substructure unit inspected at Bridge No. 6646, Pier 1, was in good to satisfactory condition. An accumulation of timber debris, consisting of logs and branches up to 18 inches in diameter, was encountered at the upstream end and along the west face of Pier 1. The embankments on both sides of the channel had some heavy erosion. The channel bottom consisted of firm material which appeared stable with no evidence of scour or appreciable changes since the previous inspection.

(A) An accumulation of timber debris, consisting of 18 inch diameter and smaller logs and branches, was observed at the upstream nose and along both sides of Pier 1. The debris extended from the channel bottom to the waterline, 6 feet off the nose, and up to 15 feet off the faces. (B) The steel icebreaker angle mounted to the upstream nose had minor corrosion throughout with more moderate corrosion near the waterline including 1/2 inch diameter rust nodules with pitting up to 1/4 inch deep.(C) Areas of section loss and impending section loss were observed at the northeast and southeast corners of Pier 1 centered on the shaft step located at 8 inches below the waterline. The section loss had up to 8 inches of maximum penetration and exposed reinforcing steel with up to 5 percent loss of section due to corrosion.(D) A spall measuring 14 inches wide by 6 inches high by 2.5 inches deep was observed 5 feet below the shaft step at the southeast corner of Pier 1. No steel reinforcement was exposed.(E) Both embankments had erosion in the vicinity of the structure.

INSPECTION DATA2.

The Bridge is a multiple span structure consisting of two modified curved-chord Pratt truss main spans with a steel grid deck, and three steel girder approach spans with a reinforced concrete deck. The superstructure is supported by two reinforced concrete abutments and four reinforced concrete piers. Pier 1, located within the waterway, is founded on untreated timber piles.

The routine underwater inspection of Bridge 6646 (CSAH No. 36 over the Red River of the North) was completed on October 18, 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 one reinforced concrete pier. According to the bridge inventory or design drawings, the pier columns rest on a rectangular concrete footing which is founded on untreated timber 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 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.

General Notes: PONTIS inspection comments -BUILT IN 1949 REMODELED IN 1965 & 1993.

313. BEARING DEVICES SOMEWHAT RUSTY. (92) NEW DEVICES ON THE WEST SPAN.(93)OVERCOATED IN 93.RUSTING AGAIN (99)(00)(01)(02)(03)(04)(06)BEARINGS ON WEST ABUTMENT TIPPED QUITE A BIT. (06)Seems that abutment has rotated some causing rockers to tip.(07)District Bridge Engineer, Nathan ,and I met at the bridge on 10/08 to look at West bearings. Clay Co. wants MN/Dot to jack up and straighten. Waiting for theirresponse.

28. WHOLE TRUSS ALONG WITH THE FLOOR BEAMS AND STRINGERS NEED TO BE PAINTED. ESPECIALLY THEFLOOR BEAMS AND STRINGERS. (92) AWHITE OVERCOAT SYSTEM WAS APPLIED TO THIS BRIDGE WHEN IT WAS REMODELED THIS YEAR. A LITTLE RUSTVISIBLE THROUGH IT BUT GENERALLY ITLOOKS REAL GOOD. (93) MANY AREAS ARE PEALING. OVERCOAT SYSTEM IS STICKING TO THE PAINT BUT WHERETHE PAINT WAS PEALING, THE WHOLEWORKS IS STARTING TO COME OFF. (94)(95)(96)SOME LARGE AREAS OF PAINT SYSTEM FAILING. (97)(98)(99)PAINTDISTRESS AREAS ARE RUSTINGAND STAINING THE OVERCOATED PORTIONS. (00)(01)(02)(03)(04)(06)(07)(08)

EXCAVATED A LOT OF FILL FROM EAST BANK TO HOPEFULLY KEEP IT FROM SLIDING ANY MORE. STARTED INWINTER OF 92-93 AND WAS COMPLETED SPRING 1993. DID INSTALL A NEW PIER ON THE EAST AND ADD 3 SPANSTOTHE EAST TO ALLEVIATE SOME WEIGHT ON THE BANK TO HOPEFULLY KEEP IT FROM SLIDDING ANY FURTHERTOWARD THE RIVER. (92)WAS COMPLETED IN THE SPRING OF 1993. SHOWS NO SIGN OF SLIDING AT THIS POINT.(97)(98)(99)(00)(01)(02)(03)(04)(06)(07)(08)

26. Concrete deck on approach spans has small hairline cracks. (01)(02)(03)(04)(06)(07)(08)

126. 2ND OVERHEAD CROSS MEMBER FROM EAST END OF TRUSS WAS HIT BY OVERHEIGHT EQUIPMENT ANDBENT. JACK HIRED A COMPANY FROM BISMARCKND TO HEAT STRAIGHTEN IT. TURNED OUT PRETTY GOOD BUT COULD USE PAINT. (03)(04)(06)(07)Lateral bracingwhich was straighten is cracked. (08)

Comment field is full. See item comments for 09 inspection and beyond.[2015] Gravel piled up on the west end of span 1should be removed so floorbeam 0 and stringers can be inspected.
