After over a decade in storage, massive 120-foot-long concrete wall beams are being transported by barge from Watts Bar Dam to the Chickamauga Lock Replacement Project site, marking a key milestone in improving navigation infrastructure on the Tennessee River. These beams, originally fabricated in 2013, are crucial to completing the upstream approach wall, which is now 68% finished. The transport involves careful coordination using hydraulic systems and rotating barges over several weeks, with beam installation underway. Once complete, the new lock will significantly increase efficiency for commercial navigation, processing nine jumbo barges per lockage compared to just one currently.
