GRAND RIVERS, Ky. – On Oct. 12, 2024, the U.S. Army Corps of Engineers Nashville District, in partnership with contractor Thalle Construction, marked a major milestone in the Kentucky Lock Addition Project with the first monolith top-out of the project’s Downstream Lock Monolith contract. This accomplishment reflects significant progress in constructing the new lock, which aims to enhance navigation efficiency on the Tennessee River.
The milestone was achieved with the final concrete lift placed on monolith L31, located at the downstream end of the lock. From 1:30 a.m. to 7:55 a.m., Thalle Construction crews completed the placement of the last five-foot layer of concrete, known as a lift. A total of 17 lifts were placed to complete this monolith.
“This is a tremendous step forward for the Kentucky Lock Addition Project,” said Army Capt. Rachel Nelson, Kentucky Lock Addition project manager-forward. “The successful top-out of monolith L31 represents the dedication and hard work of our entire team. It’s the first of many milestones that will bring this project closer to completion.”…
