Due to the impacts of construction on lockage efficiency at Kentucky Lock as well as the current and upcoming closures at Barkley Lock, a night shift is being added to the second helper boat currently required to assist upbound lockages. This additional shift is meant to reduce the queue for upbound vessels. The first night shift is planned for the night of July 23, 2020, which will result in 36 hours of continuous service by the second helper boat. The next night shift is planned July 27, 2020. From that point forward, the night shift for the second helper boat will be two nights on and the two nights off. It is expected that this night shift will continue until its services are deemed not to be required or until the ongoing guard cell construction is complete, expected to be by early September 2020. Kentucky Lock is located at Tennessee River mile 22.4 in Grand Rivers, Kentucky. Call Kentucky Lock at 270-363-4222 for more information.
