Initial Soo Replacement Lock Contracts Complete

U.S. Army Corps of Engineers announced the completion of two contracts that initiated construction of the proposed new Poe-sized lock at the Soo Locks, located on the St. Marys River in Sault Ste.

The contractor used the $3,184,534 contract to complete construction of a coffer dam at each end of the Sabin Lock to allow for dewatering as the U.S. Army Corps of Engineers prepares for future construction. The coffer dams were constructed, in simple terms, by driving steel sheet piling, in a circular pattern, into bedrock then filling the cells with stone material.

Pittsburgh District

For the first time in the history of the inland navigation system, a dam floated. The Braddock Dam Segment One floated into place and set down on Dec. 7, mating underwater with 47 drilled shafts that make up the dam segment's foundation. Vertical and horizontal alignment of the segment came within one inch of the design. Segment One, the larger of two segments, is a reinforced concrete marine structure 330 ft. long and weighing 16,600 tons. On Dec. 5 towboats moved it from the project outfitting pier a mile-and-a-half upstream, then it was sunk in place. Underbase grouting filled the gap between the river bottom and underside of the dam segment.
