A tow boat pulls out a barge after a gantry crane picked up a 1.3 million pound concrete shell Aug. 3, 2018 downstream of Kentucky Lock in Grand Rivers, Ky. The U.S. Army Corps of Engineers Nashville District and contractor, Johnson Brothers, were preparing to place it on the riverbed where it will be part of a coffer dam and eventually a permanent part of the new lock wall for the Kentucky Lock Addition Project. An issue with the strand jack delayed the placement of the concrete shell until Aug. 6. It is the first of 10 shells being placed over the next year. The lock is located at Kentucky Dam, which is a Tennessee Valley Authority project at Tennessee River mile 22.4.
