Theflood undermined the entire footing of the culvert shownand the south end of the culvert dropped about 4 the high water subsided timbers were placed overthe culvert to carry the railroad traffic, and as soon asthe flood abated the normal stream was pumped out dryin order to make an inspection of the damage and ascer-tain how repairs could be made in an economical and sat-isfactory manner. In order to keep the stream below the foundation level,. BH1I)(;K in ILACE. WITH NORMAI^ .STREAM FLOWINGTHROUGH AFTER REPAIRS WERE COMPLETED a 3-in. centrifugal pump was used on the south side anda 4-in. centrifugal pump was placed on the north sideof the bridge. As shown in one of the accompanyingillustrations it was found that the entire footing wasundermined and that the culvert was practically rest-ing on the tips of the wing walls. As there were nofractures in the concrete, it was determined to try andjack the culvert up to its original position and then re-place the foundation. Earth was excavated from thesides of the culvert in order to free the batter and jackswere then placed under the entire footing course. Ap-proximately 900 tons capacity in jacks was used and theculvert was successfully raised to its original positionwithout a single fracture developing in the concrete. With the culvert in place a new footing course wasrun in and the jacks were removed. The repairs as out-lined cost $650, and a replacement of th
