CHATTANOOGA, Tenn. (April 18, 2025) – The U.S. Army Corps of Engineers Nashville District, in partnership with Shimmick Construction and Tennessee Valley Authority, recently began erecting massive miter gates for the Chickamauga Lock Replacement Project. This milestone brings the project closer to its goal of enabling both recreational vessels and commercial barges to pass through the new lock chamber, a critical step in modernizing regional infrastructure.
