| 摘要： | Work continues on the addition of a second chamber at Kentucky Lock, with completion of the downstream cofferdam contract sometime in February projected to temporarily ease navigation delays that have been common over the last several months. The earliest possible completion date for the entire project, at the Kentucky Lake reservoir of the Tennessee River, is in 2025, said Don Getty, project manager for the Nashville Engineer District. "That's assuming everything goes well," Getty said. The Kentucky Lock project includes adding a new lock twice as long as the existing 600-foot-long lock at the dam to reduce the significant bottleneck caused by high Tennessee River traffic levels and the current lock's size. The Corps of Engineers has an 80 percent confidence level in completion no later than 2028. Both figures take into account expected periods of high water. Construction on the project began in 1998, and the total cost is expected to be $1.2 billion when completed, requiring an investment of $562 million above which have been received so far and have not yet been awarded as part of contracts and contingencies projected through the projected construction timetable. Work at the Kentucky Lock in 2020 and into 2021 has focused primarily on two ongoing contracts: for the downstream cofferdam and for the lock chamber excavation. |
