Details Chickamauga Navigation Lock, seven miles upstream of Chattanooga, TN, at river mile 471, is owned by the Tennessee Valley Authority and operated by the U.S. Army Corps of Engineers. The existing 60’x360’ Chickamauga Lock suffers from Alkali Aggregate Reaction (AAR), commonly referred to as “concrete growth,” which is the physical expansion of the concrete due to a reaction between the alkali in the cement and the aggregate. The existing lock has a finite remaining life, due to the AAR, that threatens its structural stability and operability. The replacement 110’x600’ lock will be able to pass 9 barges per lockage versus the current 1 barge per lockage resulting in an 80% reduction in commercial transit times. Chickamauga Lock passes approximately 1 million tons and 3,000 recreational vessels annually, the most active recreational lock on the Tennessee River.
