Congressman Chuck Fleischmann (Right), Tennessee District 3, huddles with U.S. Army Corps of Engineers officials Aug. 3, 2016 near the downstream miter gates inside the Chickamauga Lock chamber located on the Tennessee River in Chattanooga, Tenn. The lock is currently empty while maintainers inspect and repair the lock. The ongoing repairs make it possible to prolong the life of the lock that has been suffering from concrete expansion, which threatens its structural integrity and limits the lifespan of the lock.
