Marine MAKING DEEPER WATER FOR THE REPLACEMENT LOCK > Projects > Making Deeper Water for the Replacement Lock INSIDE THE PROJECT One of the early phases of the proposed Replacement Lock in Sault Ste. Marie, MI required deepening the Federal Channel in the downstream approach to the new lock. The deepening required drilling and blasting 77,000 cubic yards of in-situ material consisting mostly of virgin Jacobsville sandstone. Once blasted the material was excavated and loaded into barges. A tug and barges transported the material upstream to the disposal area where it was unloaded and hauled to the Government-furnished disposal area and placed. Using explosives in the proximity of the Federal Channel and Soo Locks required working closely with the US Coast Guard, ATF, and Corps of Engineers. The blasting activities so close to the existing lock structures required extensive monitoring throughout the project. WHY IT MATTERS The downstream deepening of the approach for the Replacement Lock is now complete. When Lawmakers decide to fund the new lock this dredging work will be 100% complete.
