CHATTANOOGA, Tenn. (Oct. 17, 2019) — Crews placed concrete today for the first monolith for the Chickamauga Lock Replacement Project on the Tennessee River.

An overland 1,300-foot belt system with a 24-inch belt transports concrete within two-and a-half minutes from the batch plant to the construction site. The towerbelt placing system incorporates two Terex tower cranes capable of lifting 16,400 pounds a distance of 229 feet to place concrete in the lock area.

It will take 4,500 tons of reinforcing steel and 250,000 yards of concrete to construct the new lock chamber. That is enough concrete to pave a two-lane highway from Chattanooga to Nashville. The concrete placed will make up the upstream part of the 110-foot by 600-foot lock chamber.
