The new 110' x 600' Chickamauga Lock is being designed and constructed by the Nashville District, U.S. Army Corps of Engineers. Chickamauga Lock, which is located 7 miles upstream of Chattanooga, Tennessee, is owned by the Tennessee Valley Authority and operated by the U.S. Army Corps of Engineers.

Project Abstract:

• A concrete aggregate problem will cause the current lock to be closed without aggressive maintenance.

• Construction was initiated in summer 2007, and a Road and Bridge Relocation contract ($16M) was completed in FY07.

• $27 million was available in FY07 for cofferdam construction and lock design.  

• $35 million is in the FY08 budget to continue construction and design.

• Construction of the new lock will follow the 34-month cofferdam contract.
