PROJECT DESCRIPTION: The scope of this project will consist of the construction of river and middle approach walls downstream from the lock, decommissioning the existing lock, the wet commissioning of the lock chamber constructed in the lock chamber contract, and site restoration activities at the project site. Downstream lock approach walls will be constructed from pre-cast concrete beams that were fabricated in 2012 and are currently stored at another Tennessee Valley Authority (TVA) facility until ready to be installed at the project. The downstream approach wall will extend under and through the Norfolk Southern Railway Bridge. Two (2) new 30-foot diameter mooring cells will be built downstream of the new lock. Once the existing lock is closed, a portion of the lock chamber and the associated wall culverts will be plugged with concrete. A concrete thrust block will be installed to resist concrete expansion in the dam, and the remaining area will be filled with stone. Miscellaneous equipment and buildings will be removed. No cofferdams will be required for decommissioning the existing lock, but installation of needle dams (similar to a cofferdam, but more temporary) may be required for dewatering of the chamber.
