Paducah, KY – The US Army Corps of Engineers has awarded an almost $41 million contract to begin work building the 100-foot-high concrete walls of the Kentucky Lock Addition Project, spanning the Tennessee River between Livingston and Marshall Counties. The contract is funded by federal stimulus money and goes to North Carolina-based Thalle Construction. It is the seventh awarded in the lock project. WPSD-TV reports work should begin at the start of next month. The new lock system will expand the existing one to increase capacity and speed up river commerce.
