The new 110' x 600' Chickamauga Lock is being designed and
constructed by the Nashville District, U.S. Army Corps of Engineers.
Chickamauga Lock, which is located 7 miles upstream of
Chattanooga, Tennessee, is owned by the Tennessee Valley Authority and operated by the U.S. Army Corps of Engineers.
Project Abstract:
A concrete
aggregate problem will cause the current lock to be closed without
aggressive maintenance.
Construction was initiated in summer 2007, and a Road and Bridge Relocation
contract ($16M) was completed in FY07.
$27
million was available in FY07 for cofferdam construction and lock design.
$35 million is in the FY08 budget to
continue construction and design.
Construction of the
new lock will follow the 34-month cofferdam contract.
